摘　　要：本文从系统论的思想出发，研究了区内印支运动以前的若干古老构造体系稍微固结之后又发生的非联合复合构造体系，即是经印支运动对古老体系扭动、位错、旋转所造成的一系列有其成生联系的陆梁、陆槽及其更次级的凹陷沉积盆地、穹隆、莲花状、涡轮状、“Ｓ”型、多字型等构造，以及与其相伴随的岩浆侵入喷出活动、多金属矿化带、矿床、矿体等是一系列有规律的组合，这种组合是在统一的应力场条件下形成的反“歹”字型构造体系。Proceeding from the systematological view.the author has studied nonconjunt and non -compounding tectonic systems that occurred after slight consolidation of several pre-Sinian old tectonic systems in the region under study. A series of genetically related anteklises and synekises and their second-order structures such as sedimentary downwarped basins, domes and lotus-shaped,turbine-like,s-shaped and xi(e) -type structures resulting from the torsion dislocation and rotation of old tectonic systems caused by the Indo-Sinian movement and their associated magmatic intrusion and extrusion and polymetallic mineralization zones.oredeposits and orebodies constitute a series of regular combinations which are the reversed eta(η)-type tectonic system formed in a unified stress field.
