筠连煤田位于四川盆地西南隅,筠连县和珙县境内,面积约1000公里~2。大地构造位置处于扬子准地台滇黔褶断区之娄山坳陷褶断束的西端~[1]。该煤田是四川省最有开发远景的煤田之一。本文主要依据先期勘探的部分资料,扼要阐述晚二迭世含煤建造的沉积特征;並作初步的成因分析和探索。
Junlian coalfield is located in the southwestern corner of Sichuan Basin, Junlian County and Pixian territory, an area of about 1000 km ~ 2. The tectonic position of the earth is located at the western end of the fold fault bundle of Loushang Depression in the fold area of the Yangtze-quasi-platform Yunnan-Guizhou province [1]. This coalfield is one of the most developed coalfields in Sichuan Province. Based on the partial data of the previous exploration, this paper briefly describes the sedimentary characteristics of the Late Permian coal-bearing construction, and makes a preliminary analysis and exploration of the causes.
