摘要
锑矿是贵州的重要特色矿产,地质勘查与研究走过了70多年的历程,获得不少成果。本文在广泛收集历年大量资料的基础上,通过整理与综合分析,在简述工作开展状况下,着重阐述了地质勘查与研究在查明资源、掌握产出特征、成因认识以及开发利用四个主要方面取得的进展.其中突出论述了贵州锑矿产出的五个特征——地层岩性与锑矿产出密切相关;构造控矿显著;锑矿类型多样;矿石单一,易选易炼;硅化蚀变是找矿的重要标志。并以较多篇幅,记述了锑矿成因研究认识的不断深化。
Sb-ore is an important mineral of characteristics in Guizhou. This paper, based on a large unmber of data collected over the years, expounds the advance made from four aspects, and especially deals with the five features of Sb occurances and two principal aspects of the unceasingly deepened cognition of the Sb-ore formation cause.
1. The resource distributions and rich reserves have roughly been made clear. It has been found that Sb-ore oc-currs in over 20 countries and cities and over 80 ore deposits and points have been discovered in the whole province. Sb-ore mainly occurs in Qinglong, Dushan and Rongjiang, etc. and the rich reserves ascertained rank the third of the whole country.
2. The Sb-ore occurance features have been known well. The main features are that stratigraphic lithology is closely related to Sb-ore occurances, structures clearly control ore, types are various, ore is single, easily dressed and refined, and silicification alterations are important signs of looking for minerals.
3. The cognition of Sb-ore formation cause can be roughly divided into three development periods:the cryogenic solution formation cause after magma,the bed-controlling formation cause or multiple formation cause(e. g. volcanic redeposit, syngenetic redepositional bed-controlling type, etc.) and the mantle solution formation cause.
4. Sb-ore has good exploiting prospects. The exploitation has been going on since 100 yesrs ago, developing rapidly since 1950s and increasing greatly since 1980s. From 1952 to 1989, 76000 tons of pure Sb was produced in the whole province. In history, Guizhou is the second Sb production and foreign trade export base next to Hunan Province in China.
