东秦岭松树沟蛇绿岩区的构造样式

Tectonic Framework of Songshugou Ophiolitic Melange Region in Eastern Qinling Orogenic Belt

松树沟蛇绿岩产于东秦岭碰撞缝合带，对该地区详细的地质填图表明其构造基本样式为一系列不同尺度的线状强剪切变形带与透镜状弱变形域在空间上有规律的交织组合。

Songshugou ophiolitic melange bearing chromite deposits locates the strctural zone of Eastern Qinling. Based on geological mapping, the foundational tectonic framework of this region has different scales of anastomosing associations of highly deformed linear belt with lenticular less deformed domains. This is related mostly to the deformation partitioning in the collision structural zone.
