| 摘 要： | 会泽铅锌矿区位于拗陷背景内的长期隆起-张裂构造环境之中,有良好的导矿与输矿-容矿断裂网;有多层供矿矿源层,矿源丰富。华力西期幔源玄武岩浆喷发,除本身带来部分深源矿质,并对矿源层改造、萃取矿质,形成第一期火山热液贫矿化。因广泛存在与酸性岩有关的伴生元素组合和锗的富集,加之铅同位素模氏年龄、包体测温二组数据、上贫下富两类不同硫化矿石的存在等证据,推断深部存在燕山期与热液叠加矿化有关的酸性岩体。从而在构造简单、岩性单一,又无岩浆出露的扬子准地台区产出超大型会泽富锗铅锌矿床。

| Abstract: | The Huize Pb-Zn deposit occurs in fractured-uplied environment of the downwarp setting and with the rift meshwork which for mineral transmitting and mineral locating, and with abundant source of ore supplied by its multilayer source bed. the poor ore mineralization of volcanic hydrothermal solution for the first stage was formed during the Variscan, the eruption of basalt magma brought part mineral matters from deep source and extracting minerals by the reformation of its source bed. with evidences of riches in associated elements combination germanium related to broad output acidic rock and model age of lead isotope, two group data from unified temperature of inclusions, as well as the occurs of two kinds of sulfide ore which poor in the top and rich in the down part. it is conclude that there are acidic rock body related to thermal fluid stack mineralization of Yanshanian in the deep area, and the super sized germanium rich lead -zinc deposit occurs in the paraplatform with the simple structure and singleness lithology and without magmatic rock crop out. |
