The SMG with a known gold mineralization is exposed as a small, elongated granite body hosted within the biotite gneisses of the Pezinok Group that are missing in the main Bratislava granite massif, because of a deeper erosion level. The high-potassium content, peraluminous and magnesium character of studied SMG granites are analogous to the evolved felsic members of the main granitic body. However, new dating results, i.e., a zircon U–Th–Pb isotopic age of 363.5 ± 2.1 Ma and a monazite chemical Th–U–Pb age of 360.7 ± 2.8 Ma are different from the magmatic age of ca. 355–353 Ma determined for the main granite body of the Bratislava massif. It is suggested that melting of the SMG granite source occurred during the initial stage of the Variscan continental collision before ca. 360 Ma, while the main granitic body of the Bratislava Massif was formed in the course of the late-collision granite flare-up before ca. 355–353 Ma.</p></div>","PeriodicalId":18547,"journal":{"name":"Mineralogy and Petrology","volume":"120 2","pages":"395 - 413"},"PeriodicalIF":1.1,"publicationDate":"2026-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00710-026-00988-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148173257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In most examples, at any pressure relevant to crustal magmatism, orthopyroxene will be stable to <i>T</i> &gt; 935 °C, in typical calc-alkaline metaluminous or peraluminous granitic magmas. Once such magmas cool to between 800 and 750 °C, almost all the ferromagnesian component will have crystalised as pyroxene. On further cooling, orthopyroxene will react to biotite within a narrow temperature band (~ 30 °C). Textures in granitic rocks attest to this, although the significance of the textures produced by this reaction can be overlooked. Pristine orthopyroxene is rarely found in fully crystallised granitic rocks because such preservation would require solidification at <i>P</i> &lt; 1 kbar. During crystallisation at higher <i>P</i>, biotite-quartz aggregates replace orthopyroxene, resulting in a variety of diagnostic textures. Due to the normal, high-temperature, perisolidus, textural modifications in granitic rocks, the biotite-quartz pseudomorphs after early-formed orthopyroxene may be disregarded or simply described as ‘mafic clots’. As the presence of orthopyroxene has important implications for the temperatures and H₂O contents of granitic magmas, we present an atlas of textures to assist in recognising these pseudomorphs. An important implication of the presence of orthopyroxene near the liquidi of many granitic magmas is that they formed at <i>T</i> &gt; 800 °C, through fluid-absent or H₂O-undersaturated melting of biotite-bearing or biotite + hornblende-bearing assemblages. Complete supersolidus reaction of orthopyroxene to biotite would be prevented by significant melt loss from the system. Thus, the rarity of orthopyroxene in granitic rocks indicates that fractional crystallization of granitic magmas at <i>T</i> &gt; 750 °C is uncommon and that the loss of a silicic volcanic liquid fraction is also generally unlikely.</p></div>","PeriodicalId":18547,"journal":{"name":"Mineralogy and Petrology","volume":"120 2","pages":"381 - 393"},"PeriodicalIF":1.1,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00710-026-00990-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148173121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multistage tectonic evolution of the complex started with siliciclastic deposition presumably in an accretionary wedge that may have lasted from ca. 600 Ma to ca. 517 Ma. The age spectra are dominated by Neoproterozoic zircon grains indicating that the complex was most likely sourced from the Arabian–Nubian shield, with a contribution of older Proterozoic and Archean grains from the more westerly Saharan metacraton. The deposition was partly overlapping in time with Cambrian to Early Ordovician mafic magmatism that formed either as mafic underplate below the accretionary wedge or outboard, being later accreted as part of the lower plate. The wedge was then intruded by compositionally diverse granitoids from ca. 500 Ma until ca. 440 Ma. By comparing the Ediacaran and Early Paleozoic evolution of the Ötztal Complex with originally more westerly Cadomian-basement terranes (e.g., those now found in the Bohemian Massif), we concluded that the Cenerian orogeny was generally younger in the proto-Alps than elsewhere in the former Cadomian belt. This was possibly due to a significantly curved geometry of the northern Gondwana margin and/or due to an eastward ridge–trench–transform triple point migration. Arrival of a warmer part of the oceanic plate then may have caused mantle melting, mafic underplating, and voluminous granitic plutonism in the forearc, perhaps finally terminated by ridge–trench interaction and slab break-off.</p>\u0000 </div>","PeriodicalId":18547,"journal":{"name":"Mineralogy and Petrology","volume":"120 2","pages":"415 - 439"},"PeriodicalIF":1.1,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00710-026-00987-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148173420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mössbauer spectra were collected from room temperature (RT) to 750 °C, and the sample was then cooled to RT. The initial samples contained siderite as the only Fe-mineral, and its content in the analyzed samples was greater than 80%.

The analysis shows that iron carbonates transform directly into magnetite. Then hematite generation occurs as long as siderite is present in the sample because, during its decomposition, oxygen is produced, which enables the oxidation of Fe²⁺ ions in magnetite and the formation of hematite. Changes in hyperfine parameters, such as isomer shift, quadrupole splitting, and hyperfine magnetic field, as a function of temperature were obtained for iron carbonates and iron oxides (hematite, magnetite). These results have not yet been published and allow the identification of iron carbonates and iron oxides in other materials exposed to high temperatures.

The metaperidotite zone occurs as the ENE-WSW linear zone (width: ~4 km) at the center of the Ray-Iz peridotite massif. We sampled peculiar orthopyroxene-rich peridotites from the metaperidotite zone that contain radial aggregates of orthopyroxene. This investigation provided insights into the key petrologic nature of the Ray-Iz peridotite massif, particularly its P-T history. The orthopyroxene-rich peridotites and their surrounding metaperidotites contain various metamorphic minerals, such as tremolite, chlorite, serpentines (lizardite and chrysotile), and talc. Furthermore, olivine and orthopyroxene in these lithologies contain minute inclusions of opaque spinels (“ferritchromite” and Cr-rich magnetite) and other metamorphic minerals (tremolite, chlorite, serpentine minerals, etc.). The spinel occurs both as discrete grains and inclusions in the rocks containing abundant radial orthopyroxene aggregates and exhibits low Al and high Fe³⁺ concentrations, and the contents of Ca, Al, and Cr in orthopyroxene are extremely low. The presence of high-Fe³⁺ spinel inclusions in olivine and orthopyroxene, combined with the presence of radial aggregates of orthopyroxene and the extremely low Ca and Al concentrations in orthopyroxene, indicates deserpentinization as the origin of the metaperidotites, including the studied orthopyroxene-rich peridotites. Contact metamorphism appears to be unbefitting as the cause of the deserpentinization because of the lack of a heat source close to the Ray-Iz massif.
