摘要
四川盆地南部的自贡—宜宾—带，因受燕山运动影响，导致以滨湖沉积为主的新田沟组向上突变为以河道边滩和洪泛沉积的沙溪庙组。它们沉积特征各异，其间地层缺失明显，接触类型复杂。
Yanshanian movement resulted in sudden change of the Xintiangou Formation mainly consisting of lakeshore sediment into the Shaximiao Formation consisting of point-bar and floodplain deposits in Zigong-Yibin belt, south Sichuan. This paper outlines their stratigraphy and contact.
