Abstract
The Carboniferous and Permian System in North China Platform and its adjacent area can be divided into 4 facies zones, 12 facies and 8 subfacies.Within the area, lagoon facies, carbinate paraplat form facics and deltaic facies well developed in the Carboniferous, while alluvial facies, deltaic distributary plain facies and lacustrine faciee well developed in the Permian. Paleo-geographically speaking, the platform was surrounded by an old land, anticlises(underwater uplifts) and chain islands respectively in north, west and south.The distribution of the facies were controlled predominently by Yinchan oldland, and the peleoclimate changed from warm and moisture to hot and dry.
