摘要
通过构造解析认为陕西洛南地区陶湾岩群构造层具有垂向结构特征 .其中下部构造层为泥质白云岩、泥灰岩及含砾泥砂岩组合 (Pt2 ) ,相当于准原地系统 ;中部构造层为钙质砾岩层 (三岔口岩组 ) ;上部构造层为片状大理岩层 (屈涧岩组 )和绿色片岩 (石板河岩组 ) .控制陶湾岩群区域分布及内部结构主要是近平行秦岭造山带剪切带和近水平的滑脱构造带 。
The Taowan lithogroup is located in the tectonic joint of Qinling orogenic belt and Huabei massif. It has been reformed by multiple phases of deformation. Taowan lithogroup is shown the vertical building on tectostratigraphy, from bottom upwards there is the dolostone schist of mud and sand, the conglomerate and the marble_schist of sericite and quartz. The tectonic framework of Taowan lithogroup is the shear zone lattice made up near the horizontal shear zones and the parallel Qinling mountain shear zones.
