作者曾对马角坝地区之陈家坝——二郎庙间的梓潼河一至三级阶地砾石层开展粒组分析工作,共测六个点,砾石测量点的分布见图1。图中№1a为陈家坝附近一级阶地测量点,№1b为王家崖南面二级阶地测量点,№1c为陈家坝三级阶地测量点;№2a、№2b、№2c分别为二郎庙附近一级、二级、三级阶地测量点。兹将以上各阶地砾石层的岩相特征及岩组分析结果叙述如下:
The authors conducted a particle analysis of gravel layers from the first to third terraces of Zitong River between Chenjiaba and Erlang temples in the Majiaba area, measuring a total of six points. The distribution of gravel measurement points is shown in Fig. 1. Figure № 1a for the first terrace near Chenjiaba measuring point, № 1b for the Wangjiaya south terrace measuring point, № 1C for the Chenjiaba terrace terraces measuring point; № 2a, № 2b, № 2c were Jiro Temple near the level, two, three terraces measuring points. Hereby, the lithofacies characteristics and rock group analysis results of the above graded gravels are described as follows:
