从江翁浪金矿中的构造变形特征研究

Structural Deformation Characters in Wenglang Gold Deposit of Congjiang

从江翁浪金矿是一个受构造控制明显的金矿床,金矿主要富集在受顺层剪切控制的强变形带内。本文通过对翁浪金矿控矿构造中变形岩石的宏观和微观变形特征分析,得出研究区顺层剪切带的运动学特征为逆冲型剪切,控制金矿产出的强变形带以韧性变形为主的认识。

Wenglang gold deposit is controlled by the structure obviously, the gold deposit mainly concen- trated in the strong deformation zone which be controlled by bedding shear. By analysis the macroscopical and microscopic deformation character of the deformation rock in the Wenglang gold deposit control structure, it＇ s known that in the target area, the kinematic character of bedding shear is thrust shear, the strong deformation zone which control gold occurrence mainly is ductile deformation.
