摘要
在分析矿床地质特征的基础上,通过收集大量的资料和野外地表及蚀变矿物填图,利用偏光显微镜作为主要手段,选取不同的矿带制作样品薄片作为研究对象,断裂发育、地层岩性及流体运移的多期多阶段性,是矿化蚀变分带的关键因素。总结建立矿床的蚀变特征,从中发现规律以指导找矿。
On the basis of analyzing the geological characteristics of the deposit, through collecting a large amount of data and mapping the surface and altered minerals in the field, using polarizing microscope as the main means, selecting different ore belts to make sample slices as the research object, the multi-stage and multi-stage nature of fracture development, stratigraphic lithology and fluid migration is mineralization erosion. The key factors of the variational band. The alteration characteristics of the deposit are summarized, and rules are found to guide prospecting.
