LA–ICP–MS zircon U–Pb dating for the medium-fine grained- and medium-coarse grained-biotite monzogranite of Dayishan pluton yields emplacement ages of 154.5 ± 1.6 Ma (MSWD = 2.0) and 155.5 ± 0.5 Ma (MSWD = 1.9), respectively, which are consistent with the muscovite ⁴⁰Ar-³⁹Ar plateau age of 150.4 ± 0.9 Ma for the quartz vein type ore veins. It is indicated that the Sn mineralization in the Wujiaping deposit is related to the Late Jurassic granitic magmatism. These granites show the geochemical features of highly fractionated S-type granite: 1) low Zr + Nb + Ce + Y contents (&lt;209 ppm); 2) high A/CNK ratios (&gt;1.1); 3) low crystallization temperature (mean = 688 °C); 4) high Rb/Sr ratios (mostly &gt; 48); 5) high differentiation index (DI &gt; 90); and 6) low CaO, P₂O₅, Sr, and Eu contents. Whole rocks isotopes show that these granites shows variable initial ⁸⁷Sr/⁸⁶Sr ratios (0.70251–0.71208), negative ε_Nd(t) values (−7.94–5.62) and old two stage Nd model ages of 1491–1563 Ma. LA–MC–ICP–MS zircon Lu–Hf isotopes show that the medium-fine-grained monzogranite have positive ε_Hf(t) values of 0.37–8.5 and two stage Hf model ages of 662–1180 Ma, whereas the medium-coarse grained-biotite monzogranite have negative ε_Hf(t) values of −6.42–3.55 and two stage Hf model ages of 1431–1599 Ma. It is proposed of that these granites are originated from melts mixed by crustal- and mantle-constituents and are formed in an extensional setting caused by the subduction of the Palaeo-pacific plate. The low Log<em>f</em>O₂ values calculated through zircons (−21.2–13.1) and high F contents (3630–5120 ppm) indicate the granites derived from reduced and F-rich melts. Therefore, the reduced melt is highly fractionated and enriched in Sn and F, resulting in the large scale Sn mineralization in the Dayishan ore field.</p></div>","PeriodicalId":54172,"journal":{"name":"Solid Earth Sciences","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.sesci.2021.06.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44654719","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}

Tongcheng area in the eastern margin of northern DOB is the tectonic node that connects the WNW-trending DOB and the NE-trending TLFZ. The typical ENE-NE-trending gneiss belts penetrably developed in Tongcheng area provide an ideal natural lab to decipher the transformation between the DOB and the TLFZ. Here we conduct an integrated structural and geochronological research on the ENE-NE-trending gneiss. Zircon U–Pb dating on the ENE-NE-trending gneiss yielded metamorphic ages ranging from 255 ± 9 Ma to 203 ± 10 Ma. The weakly deformed veins which intruded the surrounding gneiss yielded two groups of ages, 825 ± 29 Ma to 713 ± 7 Ma and 125 ± 2.6 Ma (weighted mean age), which indicate the protolith age of surrounding rocks and the intrusive timing of the vein, respectively. Integrated structural, microstructural and kinematic analysis indicate that no lateral structural superposed on the gneiss or veins. Therefore, it can be speculated that the deformation and metamorphism of the gneiss should simultaneously formed during the Early Triassic, as a result of continuous tearing from the DOB to the northeastern Sulu Orogenic Belt (SOB) during subduction of the Yangtze block beneath the NCB. Formation of the tearing belts, i.e., the ENE-NE-trending gneiss belts, accomplished the tectonic transformation between the DOB and the TLFZ. They could be regarded as an embryonic form of the TLFZ, which are also apparently different from the TLFZ by characteristics of non-strike slipping.</p></div>","PeriodicalId":54172,"journal":{"name":"Solid Earth Sciences","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2451912X21000532/pdfft?md5=41a4e5ab74bda2b0e28c7c1e12c9b45c&pid=1-s2.0-S2451912X21000532-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46838724","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}

This study applies a numerical modeling approach to identify the key processes associated with the formation of the deposit that cannot be easily identified using traditional analytical approaches, including the duration of the mineralizing process and the genesis of iron orebodies within intrusions associated with the deposit. This approach highlights the practical value of numerical modeling in quantitatively analyzing mineralizing processes during the formation of mineral deposits and assesses how these methods can be used in future geological research. Our numerical model links heat transfer, pressure, fluid flow, chemical reactions, and the movement of ore-forming material. Results show that temperature anomaly and structure (occurrence of the contact of intrusion and the Triassic Xujiashan group) are two key factors controlling the formation of the Yangzhuang deposit. This modeling also indicates that the formation of the Yangzhuang deposit only took some 8000 years, a reaction that is likely to be controlled by temperature and diffusion rates within the system. The dynamic changes of temperature and the distribution of mineralization also indicate that the orebodies located inside the intrusions most likely formed after magma ascent rather than representing blocks of existing mineralization that descended into the magma as a result of stoping or other similar processes. All these data form the basis for future research into the forming processes of Kiruna-type IOA systems as well as magmatic–hydrothermal systems more broadly, including providing useful insights for future exploration for these systems. The simulation approach used in this study has several limitations, such as oversimplified chemical reactions, uncertainty of pre-metallogenic conditions and limitation of 2D model. Future development into both theories and methods will definitely improve the practical significance of numerical simulation of ore-forming processes and provide quantitative results for more geological issues.</p></div>","PeriodicalId":54172,"journal":{"name":"Solid Earth Sciences","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2451912X21000544/pdfft?md5=553bc9b838c4d6a3d1e6f22c2d53de60&pid=1-s2.0-S2451912X21000544-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46773816","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 orebodies are controlled by the fractures with NW direction, and have similar orientations, with strike of 337°–344° and dips of 20°–26° to the northeast. The potassic alteration, biotitization, silicification, sericitization, chloritization, and carbonatization are developed in the country rock. According to the relationship of mineral symbiotic assemblage and the cutting relationship of the hydrothermal veins, the hydrothermal metallogenic period of Shangjiazhuang Mo deposit can be divided into three stages: quartz-molybdenite (early stage), quartz-chalcopyrite and molybdenite (middle stage) and quartz-pyrite (late stage). We studied S–H–O isotopes, fluid inclusions and mineralization age of the Shangjiazhuang Mo deposit, aiming to clarify the genesis mechanism for the Mo deposits in the eastern Jiaodong Peninsula. The δ³⁴S value of molybdenite and chalcopyrite in the main metallogenic stage range from 4.5‰ to 5.0‰, which is consistent with magmatic sulfur.
