一、问题提出七十年代初,笔者在江苏南部无锡地区进行野外地质调查时,在太湖边龙王山—五浪山一带观察到一些零星的北西向压性构造,其中规模较大的压性断裂宽十余米,延伸数公里。如图版Ⅰ-1即为其中之一,它们既不属于某一构造体系的派生构造,更不属于伴生构造,故谈不上合理的归属。随着调查范围的扩大,在苏州、无锡、常州地区,不仅见有规模可观的压性断层,也有特征明显的褶皱构造。由于北西向压性构造存在着一定的规模和
First, the question put forward In the early seventies, the author conducted field geological survey in Wuxi, southern Jiangsu Province, in the Taihu Lake Longwangshan - Wulangshan area observed some sporadic northwest pressure structure, in which the larger the pressure Broken more than ten meters wide, extending several kilometers. Such as the plate I-1 is one of them, they neither belong to the structure of a derived structure, but also does not belong to the associated structure, it is not reasonable attribution. With the expansion of the survey area, not only impressive scale of compressional faults but also obvious fold structures have been observed in Suzhou, Wuxi and Changzhou areas. Due to the Northwest pressure structure there is a certain size and
