| 摘 要： | 长期以来，习惯上将伴(共)生锗矿的成因，归属于主金属矿的成因。代表性的会泽矿其主流派的成因认识是沉积一改造成因，而且是与岩浆岩无关的改造作用。通过对滇东北伴(共)生锗与酸性岩有关的地质特性、另一组与酸性岩有关的伴生元素的存在和深受二次矿化叠加富矿存在的事实的分析与研究，认为会泽矿深部存在尚未被揭露的与晚期主要叠加矿化有关的酸性岩体。提出早期的火山热液与晚期岩浆热液复式成矿的新观点。合理解释了在相关准地台构造单调，地表又无岩浆岩的会泽地区会产出一个超大型富锗-铅锌矿床的根本原因。

| Abstract: | From a long time,the origin of the associated(coexisted)ore is attributed habitually to the origin of themain metallic ore,the primary realization of the origin of the reprresentative deposit of Huize issedimentary-modification and the modification is irrelevant to magmatite.We analyse and study the geologiccharacteristic of the associated Ge in the Northestward in Yunnan province which relative to acidic magmatiteand contrast with the fact that the existence of associated elements relative to acidic magmatite and theexistence of ore shoot suffered deeply by second superimposed mineralizing process,we consider that there isa deep-seated acidic rock body in Huize deposit which is cloaked and relative to the late main superimposedmineralizing process.we set forth a new viempoint that the ore was formed by the early volcanic hydrothermaland the lateresidual liquor,and pragmatize the fundamental occasion that there is a super large-scall Ge richlead-zinc deposit in Huize area where is a metaplatform and it's structure is simply and no magmatiteemergence. |
