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.
楊傢杖子鉬礦田的控礦構造是在東西嚮古老基底構造之上髮育起來的一箇完整的北東嚮構造繫.區域構造應力場方嚮隨著時間的推移逐漸地從北西 -南東方嚮轉嚮為東西方嚮 ,構造線方位由NE→NNE→SN方嚮轉變 ,使本礦田受到北北東嚮特彆是近南北嚮構造應力場的疊加和改造作用.

Yangjiazhangzi molybdenum ore -controlling tectonic system is a complete NE direction con-structive 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 .
