贵州独山箱状背斜锑矿成因

摘要

The Dushan Sb ore field occurs in the Dushan box anticline which lies between the Yangtze metaplatform and the South China fold belt. The Sb ore field consists of 22 Sb deposits and ore occurrences including 1 large and 2 middle deposits which are divided into 2 types such as vain type and stratoid type. This paper has a discussion on their genesis.%贵州独山箱状背斜锑矿（独山锑矿田）位于扬子准地台向华南褶皱带逐步过渡地带，扬子准地台黔南台陷贵定南北向构造变形区东部，黔南坳陷带的独山箱状背斜核部南段近倾伏端。在该锑矿田中，共有二十二个矿床（点），其中大型矿床一个、中型二个。尤以半坡大型锑矿矿床矿量集中，矿质优良而闻名全国。矿体有半坡、蕊燃沟陡倾斜大脉和甲拜、巴年层状、似层状“整合型”两种产出类型。
