摘要
厘定了二台子金矿床的主要控矿节理和断裂,运用节理玫瑰花图分析得出矿区在成矿期的主应力方向为NNW-SSE向,矿体主要以柱状矿体的形式产出。通过对控矿断裂的级别、期次划分并与控矿节理相配套,分析了矿床的构造控矿机制与成矿规律,指出找矿方向。
The main ore-control joint and fracture in Ertaizi gold deposit are determined and the principal stress direction is NNW-SSE according to rose diagram analysis. The ore-body occurs mainly as chimney. By classification of the ore-control fractures and their stages and matching the corresponding ore-control joints we analyze the mechanism of structure control on gold ore and the ore-forming regularity in Ertaizi gold deposit and the ore-searching directions are pointed out.
