摘　　要：早二叠世早期 ,豫西地区处于热带陆表海环境。这一时期形成的海陆交替相含煤地层 ,太原组下部灰岩段中的I3 煤层 ,其直接顶、底板均为浅海碳酸盐沉积 ,煤层本身具有明显的风暴沉积层序 ,是风暴作用形成的异地煤。During early time of Early Permian Epoch,in the region of western Henanprovince ,there are environment of tropical epicontinental sea,and had formed marine-continental alternating facies of coal-bearing strata.The immediate roof and floor of I3 coal bed which located limestone member in lower Taiyuan formation,are all shallow sea carbonate sediments,and in the coal seam,there are clear storm sedimentary sequences,so it's allochthonous coal formed by storm.
