甘肃省的汞锑矿分布规律及找矿

本文介绍了世界和我国汞锑矿的成矿带的划分和基本分布情况,在此基础上对甘肃省的汞锑矿成矿带进行了划分,并说明其分布特点和产地。进一步对甘肃汞锑矿的产出地层时代、围岩特征进行了统计分析,对构造、围岩蚀变和地球化学特征进行了初步总结。回顾了甘肃的汞锑矿勘查简况,提出了对甘肃的汞锑矿找矿的建议。

DISTRIBUTION OF Hg and Sb DEPOSITS ANDPROSPECTING IN GANSU PROVINCE

On the basis of the introduction to the classification and distribution of metallogenetic zone in world and China, the Hg and Sb metallogenetic zone in Gansu Province is divided as south metallogentic zone of west Qinling and Qilianshan metallogentic zone. By studying the statistics of Hg and Sb occurrences, it is supposed that the time of strata which host Hg-Sb minerals mainly is in Triassic, while Devonian as the second, the host rock most consist of fine detrital rock, while carbonatite as the second, and the control to metallogenesis from structures, alteration of wall rock and geochemical features of Hg and Sb deposits in Gansu Province are summarized. Through reviewing 5 typical Hg and Sb deposits and activities prospecting for Hg and Sb in Gansu, the proposal is put forward at last.
