摘要: 以控矿构造因素为主线,研究了成矿构造应力场的基本特征及其控矿作用。采用有限元数值模拟法反演了成矿期构造应力状态,为宏观构造分析提供了佐证,亦为成矿预测提供了定量一半定量的实验数据,并预测了成矿远景区。Abstract: Based mainly on the ore-controlling structural factors,the authors studied the basic fea-tures of the metallotectonic stress field and its ore-controlling effects。 The structural stressregime in the mineralization stage was inverted using the method of finite-element numericalmodeling,thus providing experimental data for quantitative and semi-quantitative metallogenicprognosis.In the paper ore prospect areas are predicted.
