黔东地区铅锌矿地质特征及成矿作用分析

本文根据控矿构造格局，将黔东地区铅锌矿划为扬子准地台东缘、华南褶皱带西缘，以及扬子准地台与华南褶皱带过渡带等三个铅锌矿带，并分别对其典型矿床进行了解剖和特征描述。在此基础上，分析了铅锌矿成矿作用，将黔东地区铅锌矿分为准同生沉积型铅锌矿床和热液交代一充填型铅锌矿床两种成因类型，综述了相应的控矿条件及矿床成因。最后，进行了黔东地区铅锌矿找矿远景分析，提出了6个找矿远景区。

Geologic Characteristic of the Lead-Zinc Deposits in the Eastern Guizhou and Analysis on Metallogenesis

In this paper, the lead-zinc deposits in the eastern Guizhou are divided into three lead-zinc belts including east rim of Yangtgz para-platform, west rim of the South China folds belt and their transition zone according to the structural framework of controlling, which typical deposits are anatomized and the characteristic are depicted. Furthermore, the feature of lead-zinc metallogenesis is generalized, two types of origin are of the para -synchronic sedimentary lead-zinc deposits and hydrothermal replacement-infill type of lead-zinc deposits, corresponding controlling conditions and deposit origin are synthetically stated. Finally, studies of prospecting for the lead-zinc deposit in the eastern Guizhou is carried out with six prospeering zones presented.
