摘要
杨家杖子钼矿田的控矿构造是在东西向古老基底构造之上发育起来的一个完整的北东向构造系。区域构造应力场方向随着时间的推移逐渐地从北西-南东方向转向为东西方向,构造线方位由NE→NNE→SN方向转变,使本矿田受到北北东向特别是近南北向构造应力场的叠加和改造作用。
Yangjiazhangzi molybdenum ore--controlling tectonic system is a complete NE direction constructive system developed on an east--west ancient constructive basement . As time goes on, the direction of tectonic stress field has turned from the northwest -- southeast direction to the east--west gradually , structure line has changed by direction of NE--NNE--SN . This ore field is overlaied and transformed by tectonic stress field of NNE and nearly NS directions.
