Study on Swelling Property of Tuff in Lancang Lead Ore by Micro-analysis
摘要
Abstract
Tuff is a kind of swelling rock being of swell and collapse. Taking the tuff in Lancang Lead Ore in Yunnan as the example, the main mineral composition and its micro crystal change of the tuff are studied by micro-analysis. The result shows that in the tuff therein, the main clay mineral leading to swell is montmorillonite, and kaolinite and ledikite are not contained but a non-swelling clay mineral, chlorite, is contained. The basic reason of tuff swelling is increased interplanar distance of montmorillonite crystal.关键词
