摘要
泗顶 -古丹铅锌矿是桂北同类矿床的典型代表。矿体受构造控制明显 ,泥盆纪地层中的缓倾斜和陡倾斜断层分别控制了层脉和切层脉的形态、产状和规模 ;泗顶 -泗杰和多娄弄 -龙塘 2个短轴背斜控制了区内铅锌矿床 (点 )的分布 ;泥盆纪碳酸盐岩地层中的构造面则为矿液的运移和矿体的富集提供了有利通道和场所 ,控制了矿体的产出层位。矿床 (点 )的形成、定位都离不开这 3种构造的作用。
In Siding-Gudan Pb-Zn deposits, as a typical representative of northwest Guangxi, the form, occurrence and scale of ore-body are controlled clearly by flat and steep faults in Devonian, their distribution are limited by two anticlines with the short axis, Siding-Sijie and Duoloulong-Longtang, and the structural surfaces provided favorable passing way and position for flowing and concentration of ore fluid. Formation and location of ore deposits are controlled by the three kinds of tectonic action in the mine field.
