中文摘要
最近对弗吉尼亚州西南部蓝岭主要断裂的运动学研究提出了这样一种可能性,即这些断裂中的许多在晚前寒武纪时是伸展的,然后在古生代挤压期间局部重新激活。广泛的糜棱岩构造组构记录了剪切的意义,遗峰变质组合记录了断裂系统的底盘和上盘的条件。这些结果将严格检验这一假说,即在伊阿普图斯古生代闭合之前,早期的主要伸展构造。
英文摘要
Recent kinematic studies of major faults in the Blue Ridge of southwestern Virginia have raised the possibility that many of these faults were extensional during the late Precambrian and were then locally reactivated during Paleozoic compression. Extensive mylonitic tectonic fabrics record sense of shear and relic peak metamorphic assemblages record conditions in the foot- wall and hanging wall of the fault systems. Results will rigorously test the hypothesis for early, major extensional tectonics prior to the Paleozoic closure of Iapetus.
