福建二叠纪煤田,东邻东南沿海隆起(又称华夏古陆),北连闽西北的武夷隆起、西南与江西、广东的九连山隆起相接,称永(安)—梅(县)坳陷(亦称闽西南坳陷带)。其面积约达七万平方公里,本文涉及其中、南段约达五万平方公里。主要包括了三明、龙岩和晋江地区的永安、大田、龙岩、永定及永春等十余个县(市)。区内广泛发育了包括二叠系在内的晚古生代沉积,其由老到新为:南靖群(D_3nn)、石炭系(C);以及早二叠世的栖霞组(P_1q)灰岩、文笔山组(P_1w)砂、泥岩;童子岩组(P_1t)砂、泥岩夹煤层,往上为晚
Fujian Permian coalfield, east of the southeast coastal uplift (also known as the Huaxia ancient land), north of Fujian Province in northwestern Wuyi uplift, southwest and Jiangxi, Guangdong Jiulianshan uplift, said Wing (Ann) - Mei (county) Depression (also known as Min Southwest Depression). It covers an area of about 70,000 square kilometers, of which this article covers an area of about 50,000 square kilometers. It mainly includes more than ten counties (cities) such as Yong’an, Daejeon, Longyan, Yongding and Yongchun in Sanming, Longyan and Jinjiang. Late Paleozoic sediments, including Permian, have been extensively developed in the area. They range from old to new: D_3nn, Carboniferous (C); and Early Permian Qixia Formation (P_1q) limestone, Wensishan Formation (P_1w) sand and mudstone; Tongziyan Formation (P_1t) sand and mudstone intercalated with coal, up late
