摘要
雪峰古陆边缘上石炭统为一套滨浅海碳酸盐岩和碎屑岩沉积。下部黄龙组为白云岩，灰岩和砾岩及少量砂岩互层，上部船山组为灰岩，白云质灰岩与砂岩及少量砂岩互层。船山组含带Ｔｒｉｔｉｃｉｅｓ带和Ｐｓｅｎｄｏｓｃｈｗａｇｅｎｉｎａ带。整个上石炭统碎屑岩和碳酸盐岩交替出现，属海水极浅的滨海陆脊滩相至局限台地相。
The Upper Carboniferous System on the margin of Xuefeng ancient land consists of shallow marine carbonate and elastic deposits. Dolomitite and limestone are interbedded with conglomerate and a few sandstones in Huanglong Formation-the lower part of the Upper Carboniferous System,and limestone or dolomitic linestone with sandstone and little quantity of coughlomerates in Chuanshan Formation-the upper part of the Upper Carboniferous system, which contains Fusulinids zones: Triticites zone and Pseudoschwagerina zone. The deposits of the Upper Carboniferous System represent a succession from shore beach facies to restric-ed platform facies.
