摘要
红色粘土型金矿床是近年来发现的一种与表生作用有关的新类型金矿床 ,在中国南方分布广泛 ,其与红土型金矿床虽然具有某些相似性 ,但它们之间的差异还是十分明显的。本文选择了云南上芒岗、贵州老万场和湖北蛇屋山 3个红色粘土型金矿床 ,研究了它们各自产出的地质背景、红色粘土层特征及矿体和矿石特征 。
The red-clay type gold deposit discovered in southern China is a new type of gold deposit formed by supergenic processes . Although similarities to lateritic gold deposid in out-looking, the red-clay type gold deposid has obviously different features to lateritic gold deposid. Three examples of red-clay type gold deposit were investigated in this work ,which are Shangmanggang gold deposid in western Yunnan province, Laowanchang gold deposid in southwestern Guizhou province, and Shewushan gold deposid in southern Hubei province, China. Comprehensive studies have been carried out on the features of red-clay profile, on the features geological background to lateritization and miralization , on features of ore body and ore. The ore forming geological condition and the main characteritic of red-clay type gold deposit in China were summarized.
