摘　　要：辽宁西部花坤头营子地区旋卷构造是板块碰撞陆内造山作用结果.该构造由内环、外环及推覆体三部分组成.内环为一个完整的莲花状构造体系,由中心向外,岩石地层单位呈一圈一圈的,由老向新排列.外环为以雾迷山组为主体的北东向的瓦房子复背斜核部.内环与外环以塌陷断层、旋转挤压断层分隔.与该构造有关的矿产有铅锌、锰矿.The vortex structure in Huakuntouyingzi area in Western Liaoning Province,which is the result of plate collision and intra-continent orogeny,is composed of inner ring,outer ring and nappe.The inner ring is a complete lotus-form structure system,from center to outside,with lithostratigraphic units arranged in circle from old to new.The outer ring is the core of NE-trending Wafangzi anticlinorium,with Wumishan Formation as the main body.The inner ring and outer ring are separated by collapse faults and rotary compressive fault.Minerals related to the structure include lead,zinc and manganese deposits.
