摘要
湘东一赣西地区是郯庐断裂南延的重要部位 .中生代以来 ,NNE向走滑构造主要由 T3～ J会聚走滑和 K～ E离散走滑构造叠加而成 ,并直接控制了该区构造样式及资源特征 .本文简要地介绍了湘东一赣西NNE向走滑构造的若干研究进展 .基于野外构造和模拟实验研究、以及湘东一赣西西段与郯庐断裂沂沭段变形特征对比 ,提出湘东一赣西更为复杂的平移构造型式很可能与该区地壳结构分层特征、前期断裂构造格局。
Eastern Hunanwestern Jiangxi(EHWJ) is an important site of TanLu fault south elongation. The NNEtrending strikeslip faulting (NNESSF), mainly compounding of T 3~J convergent SSF and K^E divergent SSF, controlled directly the tectonic patterns and evolution features in EHWJ. The progress of researches on the NNEstrikeslip tectonics was briefly introduced. Based on the study of field structures and tectonic simulation experiments as well as the comparison of deformation characteristics between YiShu segment and EHWJ segment along TanLu fault, it was proposed that the wrench tectonics in EHWJ, which are more compliated than that in YiShu area, was mainly related to the differences of the crust structural layer, the style of the preexisting faults, displacement and strikeslip tectonic formation history in this two areas.
