摘　　要：通过对高松矿田内主要断裂构造结构面、破碎带、旁侧派生伴生构造及其蚀变矿化等特征的系统深入观察研究,构造应力场分析,推断该矿田自中生代以来经历了印支期→燕山中晚期→喜山早期→晚近期的四期构造活动,其中燕山中晚期的构造活动为成矿构造;印支期活动为成矿前构造,其对成矿有一定的控制作用;后两期则为成矿后构造,其起到破坏矿体的作用。Systematic studies and observations of the main discontinuities, the rupture zones, the characters of alteration and mineralization and analysis of the metallogenetic stress field, lead us to conclude that the Gaosong field underwent four stages of tectonic activity. They are Indosinian, Early and Late Himalayan and recent tectonic activity. The Indosinian stage may have some controls on the formation of the deposits. The Early and Late Himalayan stages are the main stages of mineralization, while the recent tectonic activity just has resulted in the destruction of ore bodies.
