摘要
姑婆山花岗岩体西南接触带的新路和水岩坝钨锡矿田的控矿构造主要是侵位构造,包括侵位断裂、侵位褶皱穹起、侵位界面和侵位面理等。白面山式锡矿床,并不是以“过渡层”为矿源层成矿,而是以“过渡层”这种构造薄弱层产生犁式滑脱断裂,矿液通过侵位断裂上升沿之充填交代成矿。
The ore-control structure of Xinlu and Shuiyanba W-Sn ore-field, loating within the south-western contact zone of Guposhan granite, is mainly an emplacement structure, including emplacement faults, emplacement upfolds, emplacement bounderies and emplacement foliations, etc. The Beimianshan-type Sn ore deposit is not formed directly by the 'transitional layer', providing ore-forming resources but formed by mineralization liquor going upwards, filling and replacing the replacement fault, plow-like detachment fault, created by such weak layer as 'transitional layer'.
