| 1 | 云南白牛厂银多金属矿床喷流沉积成因证据:容矿岩石的地球化学约束显示文摘滇东南是否存在广泛的热水沉积活动已成为制约滇东南三大多金属矿床(个旧、都龙、白牛厂)成因研究的主要因素之一。系统研究了白牛厂银多金属矿床容矿岩石的地球化学特征,研究表明:矿床容矿岩石主量元素数据均投影于火山及海底热卤水成因区域内;稀土元素明显分为两组,稀土元素总量较高的样品可能与较多的正常沉积物的加入有关;稀土元素总量较低的样品具有与加拿大沙利文矿山的条带状富电气石热液沉积岩和加拿大Agnico-Eugle矿山的铁建造中的条带状燧石岩相似的稀土元素配分模式与标准化参数;同时,微量元素对的演化趋势与现代大洋热水沉积物相似,而且As、Sb和Ag含量与大厂和个旧热水沉积硅质岩相当。推测白牛厂银多金属矿床属热水沉积成矿,只是在距花岗岩体较近的部位遭受了部分叠加改造。 | 祝朝辉 刘淑霞 张乾 谷德敏 | 2010 | 现代地质2010，24，1： | 13 |

| 3 | Sulfur isotopic composition of the Bainiuchang super-large Ag polymetallic deposit,Yunnan Province,China: Implications for the source of sulfur in ore-forming fluids显示文摘The Bainiuchang deposit in Yunnan Province, China, is located geographically between the Gejiu ore field and the Dulong ore field. In addition to >7000 t Ag reserves, the deposit possesses large-scale Pb, Zn, Sn reserves and a mass of dispersed elements (i.e., In, Cd, Ge, Ga, etc.). Based on systematic studies of sulfur isotopic composition, the authors conclude: The Bainiuchang deposit experienced two epochs of metallogenesis, i.e., the Middle-Cambrian sea-floor exhalative sedimentary metallogenic epoch and the Yanshanian magmatic hydrothermal superimposition metallogenic epoch. In the two metallogenic epochs, the δ34S values of sulfides were all near 0, showing a tendency of being enriched slightly in heavy sulfur. The δ34S values of sulfides in the early metallogenic epoch are within the range of 2‰–5‰ with a peak value range of 2‰–3‰ and an average of 3.0‰, and those of sulfides in the late metallogenic epoch are within the range of 2‰–6‰ with a peak value of 3‰–4‰ and an average of 3.9‰. For the single metallogenic epoch, sulfur in the ore-forming fluids in the early epoch already reached isotopic equilibrium and was derived mainly from underneath the magma chamber or basement metamorphic igneous rocks. Sulfur in the sulfides in the late epoch was derived mainly from magmatic hydrothermal fluids formed in the process of remelting of the basement metamorphic igneous rocks. | XIE Hongjing ZHU Chaohui ZHANG Qian WANG Dapeng FAN Liangwu | 2009 | Chinese Journal Of Geochemistry2009，28，3： | 7 |
| 4 | LA-ICP-MS U-Pb zircon dating of the Bozhushan granite in Southeast Yunnan显示文摘The LA-ICP-MS U-Pb zircon dating of eight typical samples from four units of the Bozhushan granite intrusion in southeastern Yunnan Province, constrains the age of acidic magmatic intrusion in this area. Both the oscillatory zoning and chondrite-normalized REE patterns characterized by LREE-depletion and HREE-enrichment with positive Ce anomaly and negative Eu anomaly indicate the magmatic genesis of these zircons. Eight zircon samples from the Bozhushan granite yielded a mean 206 Pb/ 238 U age of (85.58±1.0) Ma (MSWD=4.1) to (88.10±0.66) Ma (MSWD=1.8). These chronology data suggest an accurate isotopic age for the intrusion of the Bozhushan granite, and are different from the published age data of 48 to 111.5 Ma. The geochronology data of the Gejiu, Dulong and Dachang super-large deposits and related Yanshanian granites indicated that there occurred large-scale granitic magmatism and mineralization events in western Nanling region during the Late Cretaceous. | LI Kaiwen ZHANG Qian WANG Dapeng CAI Yi LIU Yuping | 2013 | Chinese Journal Of Geochemistry2013，32，2： | 5 |
