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。
泗頂-古丹鉛鋅礦是桂北同類礦床的典型代錶。礦體受構造控製明顯,泥盆紀地層中的緩傾斜和陡傾斜斷層分彆控製瞭層脈和切層脈的形態、產狀和規模;泗頂-泗傑和多婁弄-龍塘2箇短軸揹斜控製瞭區內鉛鋅礦床(點)的分佈;泥盆紀碳痠鹽巖地層中的構造麵則為礦液的運移和礦體的富集提供瞭有利通道和場所,控製瞭礦體的產齣層位。礦床(點)的形成、定位都離不開這3種構造的作用。

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.
