Metal substitution into iron (hydr)oxides has been reported to reduce Fe atom exchange rates between Fe(II)aq and metal-substituted iron (hydr)oxides and inhibit the recrystallization of iron (hydr)oxides. However, the environmental behaviors of the substituted metal during these processes remain unclear. In this study, Fe(II)aq-induced recrystallization of Cr-substituted goethite (Cr-goethite) was investigated, along with the sequential release behavior of substituted Cr(III). Results from a stable Fe isotopic tracer and Mossbauer characterization studies show that Fe atom exchange occurred between Fe(II)aq and structural Fe(III) (Fe(III)oxide) in Cr-goethites, during which the Cr-goethites were recrystallized. The Cr substitution inhibited the rates of Fe atom exchange and Cr-goethite recrystallization. During the recrystallization of Cr-goethites induced by Fe(II)aq, Cr(III) was released from Cr-goethite. In addition, Cr-goethites with a higher level of Cr-substituted content released more Cr(III). The highest Fe atom exchange rate and the highest amount of released Cr(III) were observed at a pH of 7.5. Under reaction conditions involving a lower pH of 5.5 or a higher pH of 8.5, there were substantially lower rates of Fe atom exchange and Cr(III) release. This trend of Cr(III) release was similar with changes in Fe atom exchange, suggesting that Cr(III) release is driven by Fe atom exchange. The release and reincorporation of Cr(III) occurred simultaneously during the Fe(II)aq-induced recrystallization of Cr-goethites, especially during the late stage of the observed reactions. Our findings emphasize an important role for Fe(II)aq-induced recrystallization of iron minerals in changing soil metal characteristics, which is critical for the evaluation of soil metal activities, especially those in Fe-rich soils.","PeriodicalId":229905,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Mineral Science","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122659739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fluid inclusion evidence is not available since the present fluid inclusions are very small in size for investigation under optical microscope. Boiling assemblages occur in two types of auriferous mineralization hosted by supradetachment, grey fine-grained arkosic sandstones and presented by (i) veinlets of quartz-adularia and (ii) veinlets of platy calcite. In quartz-adularia veinlets micron-sized electrum aggregates form globular shapes, which reach 800 µm across and are arranged along the veinlet length. In cross-sections electrum aggregates display abundant silicate-filled pores of a few microns in size. Globular geometry of the electrum aggregates and their arrangement along the veinlet length suggest collectively that these globules were flowing particles - flocs but not colloidal particles since the latter are much smaller. In these veinlets electrum is intergrown with micron-sized chalcopyrite, galena, hessite and greenockite. The auriferous calcite veinlets are formed later than the auriferous quartz-adularia ones, since the first clearly has intersected or brecciated the latter. Electrum in the calcite veinlets forms accumulations only in portions of sharp thickness expansions after throttle portions, which are barren. This suggests that electrum has been transported by a flowing fluid, in a particulate form and deposited due to pressure drop during hydrofracturing, as the electrum particles have been arrested in low velocity (expanded) portions of ore conduits. The auriferous assemblages in the Kupel occurrence indicate high effectiveness of boiling for deposition of Au, Ag, Cu, Pb, Cd and Te through collective loss of H2, CO2, H2S and H2Te what is in complete accord with recent studies on modern terrestrial geothermal fields. Methods used comprise observations under binocular, optical and scanning electron microscope, and electron microprobe analysis.","PeriodicalId":229905,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Mineral Science","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123812264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mineralization was synchronous to the intrusion of a Miocene granodiorite body in the footwall of the Western Cycladic Detachment System and related felsic dikes and sills within marbles and schists, which locally cross-cut the detachment. Carbonate-sericite altered microgranodioritic dikes and sills at Kamariza are crosscut by porphyry-style quartz-sericite-calcite stockworks hosting pyrrhotite, pyrite, arsenopyrite, chalcopyrite and sphalerite (e.g. the same metallic minerals present in the carbonate-replacement and vein ores). The dikes and sill display enrichment in Ni (up to 220 ppm), Cu (up to 175 ppm), As (up to 510 ppm), Mo (up to 6 ppm) and Pb (up to 830 ppm), as measured by ICP-MS. The Ni-Bi-Au association at the Clemence mine in Kamariza is a vein-type mineralization developed at the contact between marbles and schists. The mineralization also expands in the marbles unit, forming carbonate-replacement bodies. It consists of native gold and bismuthinite intergrown with gersdorffite, enclosed in galena. Bulk ore analyses reveal Au and Ag grades exceeding 100 ppm, Pb and Zn > 1 wt. %, Ni up to 9700 ppm, Co up to 118 ppm, Sn > 100 ppm and Bi > 2000 ppm. New mineralogical and mineral-chemical data from the Ni-Bi-Au association suggest gold deposition with oscillatory zoned gersdorffite following initial deposition of pyrite and arsenopyrite. Oscillatory zoning in gersdorffite is related to variable As, Ni and Fe contents, indicating fluctuation of arsenic fugacity in the hydrothermal fluid. Chalcopyrite, tennantite and enargite rimming gersdorffite suggest an evolution towards higher sulfur fugacity in the mineralization with time. Stannite enclosed in pyrite and native antimony enclosed in galena are decribed here for the first time in the Clemence ore assemblage. At the ‘km-3’ locality, the Ni sulfides and sulfarsenides, vaesite, millerite, ullmannite and polydymite, are enclosed in gersdorffite and/or galena. At this location mineralization occurs in the form of calcite and galena veins crosscutting and cementing brecciated marbles, within the detachment fault. Mineralization is enriched in Mo (up to 36 ppm), As and Ni (both >1 wt. %), Co (up to 1290 ppm), whereas other elements occur in lesser amounts: Te (up to 2 ppm), Sn (up to 8.5 ppm), Bi (up to 1.3 ppm). Gersdorffite at ‘km-3’ is homogenous and contain less Fe (up to 2 wt. %) than that from the Clemence mine (up to 9 wt. %), probably related to lower temperatures of their formation.

These minerals can be considered as pathfinders for gold as they may guide exploration to discover distinct types of gold-bearing ores. Primary gold mineralization in Greece can be subdivided in three groups regarding the mineral associations with gold: (A1) mineralization where native gold and Au-Ag tellurides accompany either Bi-sulfosalts, native Bi and reduced-type Bi-sulfotellurides (joseite-A, joseite-B, pilsenite) at Koronouda, Laodikino/Kilkis area, Stanos, Olympias-Stratoni and Fissoka at Chalkidiki area and Angistron Mt/W. Rhodope), or (A2) accompany Bi-sulfosalts with oxidized-type Bi-sulfotellurides (e.g. tetradymite and tellurobismuthite) typical for Aberdeen, Palea Kavala, Thasos island, as well as for the calc-alkaline and alkaline-hosted porphyry and epithermal deposits/prospects in western Thrace, Limnos island and Skouries; (B) deposits which lack tellurides but include Bi-sulfosalts and native gold (e.g. the carbonate replacement deposit of Lavrion, the porphyry-Cu-Mo-Au deposits of Maronia and Stypsi, Lesvos Island, and the intrusion-related Kimmeria Cu-Mo-Au deposit); and (C) deposits/prospects where native gold and Au-Ag-tellurides and other base metal tellurides are abundant and Bi-tellurides and Bi-sulfosalts are missing (the metamorphic rock-hosted quartz veins at Panormos/Tinos and Kallianou/Evia Islands, and the epithermal shallow submarine mineralization at Milos). Bismuth and tellurium are considered to be derived from magma and recognition of bismuth sulfosalts and bismuth tellurides, as well as of various types of base (and precious) metal tellurides in the mineralization, is a strong evidence of magmatic-hydrothermal contribution and of adjacent concealed intrusives (e.g. Perama Hill and Pefka deposits are cases where no granitoids are exposed). The absence of bismuth minerals and the presence of precious and base metal tellurides (as is the case for Milos, Tinos and Evia islands) may still suggest magmatic contributions but in more distal setting from a buried granitoids at depth. Selenium (and/or bismuth) bearing galena and Se-bearing bismuth chalcogenides present at Kimmeria intrusion-hosted veins, at Lavrion, as well as in several porphyry-epithermal deposits in northern Greece (e.g. Kassiteres-Sapes, Pagoni Rachi, Perama Hill, Pefka and Skouries) are indicative of high-temperature, initial stages of ore deposition from magmatic-hydrothermal fluids, and proximity to porphyry mineralized centers. When recognized in a mineralization as an accessory mineral, Se-bearing galena could guide exploration towards unexposed granitoids.

Large demands and a low domestic production characterize the availability of these mineral resources within the EU. Since 2008, several EU funded research projects have highlighted the domestic exploration and exploitation possibilities of some specific European regions. Throughout the SE Europe the Serbo-Macedonian metallogenic province (SMMP) in northern Greece is highlighted as one of the most promising exploration targets. The metamorphic terrain of the Vertiskos Unit forms the geological basement of the SMMP in northern Greece, and hosts several Oligocene-Miocene ore deposits and mineralization occurrences. Ancient and modern mining activities mostly targeted the southern part of the Greek SMMP (Chalkidiki Peninsula), while the northern part was subjected to a diachronic occasional pre-industrial exploitation. Thus, by taking into consideration the modern exploration and exploitation techniques, the northern part could be characterized as a greenfield area. The base (Cu, Pb, Zn, Fe, Mn) and precious (Au, Ag) metals endowment of the Vertiskos Unit is well-documented and among the most important mineralization of the region are the Pontokerasia Cu-Mo-Au-porphyry deposit, the Vathi Cu-Au-U±Mo porphyry deposit, and the Skouries Cu-Au porphyry deposit. However the critical and rare metals endowment of the region lacks any thorough examination. Several porphyry mineralizations hosted in high-K calc-alkaline magmatic rocks (e.g. Vathi, Gerakario, Skouries), and vein type mineralization hosted in shear-zones (e.g. Rizana, Stanos, Kolhiko, Laodikino, Stefania, Koronouda, Drakontio, Nea Madytos) are reported being enriched in Sb, Bi, Te, Co, Sn, W, Ga, Ge, In, Ta, REEs and PGEs.

We report here the first occurrence of zunyite along with alunite, quartz, APS minerals, diaspore, pyrophyllite and kaolinite in the metallogenic province of Western Thrace. \u0000 The Konos Hill prospect in Western Thrace comprises a telescoped porphyry Mo-Re-Cu-Au system, overprinted by high-sulfidation mineralization. In low topographic levels, porphyry-style mineralization is exposed and comprises pyrite-chalcopyrite-bornite-molybdenite-rheniite-bearing quartz-stockwork. Host rocks are subvolcanic bodies of granodioritic composition that have suffered pervasive sericitic alteration. High-sulfidation epithermal-style alteration occupies the higher topographic levels and has caused significant overprinting of the porphyry-style mineralization and alteration. It consists of silicified zones related to N-S and E-W trending faults, which grade outwards to advanced argillic alteration assemblages. These assemblages are characterized by abundant alunite and quartz, with minor presence of diaspore, APS minerals, kaolinite, pyrophyllite and zunyite. \u0000Zunyite forms euhedral crystals that reach in size up to 300μm. They sometimes include minor quartz and are associated with alunite, APS minerals and pyrophyllite. EPMA data revealed variations in the F and Cl content of zunyite, that range between 3.62-6.54 wt.% and 2.65-3.15 wt.% respectively. Alunite supergroup minerals display a wide compositional range and are represented by members of the alunite, beudanite and plumbogummite subgroups. Alunite and natroalunite constitute the most common advanced-argillic alteration minerals and are found in both quartz+zunyite and quartz+diaspore+pyrophyllite assemblages. Available mineral-chemical data favor the existence of compositions that cover a complete solid-solution series between Na- and K-rich varieties. Common mode occurrences comprise euhedral, tabular-shaped and rarely pseudocubic crystals. APS minerals are usually found as pseudocubic crystals forming the cores of tabular alunites. Analyzed compositions comprise woodhouseite (Sr-, Ce- and Sr-Ce- rich members were found). Diaspore forms aggregates of euhedral, coarse-grain crystals scattered in strongly silicified rock. Finally, pyrophyllite when present, forms acicular aggregates in the matrix along with diaspore and quartz. \u0000Available data suggest that the formation of the studied advanced argillic alteration assemblages is hypogene and due to ascending magmatic fluids released by the subvolcanic bodies.
