该铜矿区已辩别出破裂构造的三种应力场,即NE构造应力场,旋扭构造应力场和NNE向构造应力场。显然,这些构造应力场控制着铜矿的公布。 本文从力学和应力场观点出发,阐明了全部成矿期构造的主要特征。NE向构造应力场决定了成矿前闪长岩体的侵入;旋扭构造控制了成矿期的各种破裂;而NNE向构造应力场在成矿后活动,并破坏已存在的上述两种构造。毫无疑问,研究破裂的构造应力场与矿化阶段的关系,对于该铜矿床的勘探和开采,均具有极为重要的意义。
The copper mine has identified three kinds of stress field of rupture structure, that is, NE tectonic stress field, twist torsional tectonic stress field and NNE tectonic stress field. Obviously, these tectonic stress fields control the publication of copper. Based on the mechanics and stress field, this paper clarifies the main features of all metallogenic stages. The tectonic stress field in NE direction determines the intrusion of diorite bodies before metallogenesis. The twist-twist structure controls various types of ruptures during the metallogenic stage. The tectonic stress field in the NNE tectonism activates after the ore-forming and destroys the existing two types structure. Undoubtedly, the study of the relationship between the tectonic stress field and the mineralization stage of rupture is extremely important for exploration and exploitation of this copper deposit.
