这里打算讨论一下渭南附近黄土原的成因问题,顺便也提到有关渭河谷地构造的问题。1957年夏天,作者在这一地区工作过五天,在张伯声教授的指导下考虑过这些问题,后来因故未能整理成文。1959年春,我们返校后,喜读赵力田、张尔道两先生关于渭河谷地构造的论文(见参考文献2及3),决定提出自己的一些意见,作为对上述两文的补充。希望得到有关同志的指正。关于渭河两岸阶地的成因过去很少人讨论过。这个问题与渭河地堑的成因是相联系的。渭河的地堑性质很早就被人注意到了。后来有过不同的意见,或谓北山(渭河谷地北缘由下古生代地层组成的山系)是一个背斜,而渭河谷地是这个背斜的南翼,不过被新沉积掩
Here intends to discuss the causes of the Loess Plateau near Weinan, by the way also mentioned the issue of the structure of the Weihe Valley. In the summer of 1957, the author worked in this area for five days, and under the guidance of Professor Zhang Boshen, these problems were considered and later failed to be documented for some reason. In the spring of 1959, after we returned to school, we read papers by Zhao Lvtian and Zhang Erdao about the structure of the Weihe Valley (see references 2 and 3) and decided to put forward some opinions as a supplement to the above two articles. I hope that the comrades correct. The causes of terraces on both sides of the Weihe River have rarely been discussed before. This problem is connected with the origin of the Weihe graben. The graben nature of the Weihe River has long been noticed. Later, there were different opinions or the Beishan (a mountain system formed by the Paleozoic strata in the northern Weihe Valley) was an anticline, while the Weihe valley was the southern wing of the anticline, but was newly concealed
