| 摘 要： | 本文通过对滩间山矿区地层、构造及岩浆岩与成矿关系的研究,认为中元古界万洞沟群是金的矿源层;成矿构造具有多期次、多阶段活动的特点,矿体受单一及复合型式的构造控制;华力西期侵入体对成矿作用仅体现于为矿床的形成与再造提供热源。矿质在弱酸—中偏碱性溶液中,主要呈硫络合物的形式搬运、并在还原条件下成矿。特别指出,含磷质物地层是区内重要的岩金找矿标志之一。

| Abstract: | Through the study of the relationships between mineralization and strata, tec-tonics and magmatite in Tanjianshan mining area, the authors consider that the Middle Pro-terozoic Wandonggou Group is the source bed of gold. Metallotectonics are characterized bymultiphase activity, ore bodies are controlled by simple or composite tectonics, and Variscanintrusives act as the heat source for the formation of this deposit. The mineral materials existin weak acid --neutral (or subalkali)solution, transport in the form of sulfur complex com-pound, and deposit in reducing environments. It is particularly pointed out that the carbon--bearing strata are the one of important Au--ore guides of prospecting in the region. |
