岩接触带附近的碎裂岩带的控制,该挤压破碎带(碎裂岩带) 为该矿段矿液的运移、矿体的赋存提供了
良好的通道和赋存空间,并严格控制了金、铜、钼矿脉(体)的空间就位。同时由于不同期次、不同性质构
造应力作用的影响,致使矿段内矿脉(体)产状呈现正反倾向交互性和东西部产状的不一致性。本文着
重研究了该矿段内构造控矿因素,初步建立起矿段的金、铜、钼矿成矿模式,用以指导该区的找矿工作 |

| Abstract:The Cu-Mo-Au ore-veins in the Luandongshan section of the Baoxingchang deposit, Dali, Yunnan Province are controlled by the com鄄
pressive fracture zones along the strata and the cataclasite zone near the contact zone in the syncline core. The cataclasite zone provides not only efficient
channels for ore migration and occurrence space for ore bodies, but also controls the spatial positions of Cu-Mo-Au ore veins. Meanwhile, affected by the
multi-time and multi-nature tectonic stresses, the ore occurrence is characterized by alternating positive and negative dips and inconsistence between the
east and in the west of the Luandongshan ore section. This paper focuses on the research of the ore-control factors in this ore section, and attempts to es鄄
tablish an ore-forming model of Au-Cu-Mo for the section, which can guide further exploration in this area. |
