摘要
本文用正演的方法研究了斜交纵弯褶皱叠加地区早期裂隙产状变化规律,并用两次褶皱后的地层产状作一次复平所获得的裂隙产状与原始产状进行了对比,查明地层一次复平引起的早期裂隙产状变化误差及影响因素,提出了校正误差的方法。
Regular variation of initial fractures' occurrences during obliquely superimposed -longitudinal bend folding has been studied by a positively deductive unfolding operation in this paper. The occurre recovered by using this operation to twice folded fractures have been compared with their initial occurrences. Some factors effected on this operation and their introduced evrors have been discussed. Finally, the correct methods has been proposed.
