生物礁位于新疆皮山县桑株乡克孜里奇曼村南东500m处,属下二叠统克孜里奇曼组。礁核厚61.8m,出露最大宽度300m,与礁翼层理清晰的颗粒灰岩、中至薄层含泥灰岩和生物屑灰岩星指状接触。造礁生物以群体四射珊瑚、串管海绵、蓝绿藻和管壳石为主,苔藓虫、纤维海绵和水螅次之,多数保持了原始生长状态。造礁生物在垂向上具有明显的分带性,据此可分为障积灰岩、障积一骨架灰岩和粘结灰岩三个微相段,分别相当于礁体发育的定殖-拓殖阶段、泛殖阶段和统殖阶段。
Reef is located in Pishan County, Xinjiang Sanjuk Township Kiziliqi Mancun 500m south east, belongs to the Permian Kezi Ridicam group. Reef core thickness of 61.8m, the maximum width of 300m exposure, and the reef wing clear granular limestone, medium to thin layer of marl and bioclastic limestone finger contact. The reef-building organisms are dominated by coral, string-tube sponge, blue-green algae and shell rock, followed by bryozoans, fiber sponges and mats, most of which maintained their original growth status. The reef-forming organisms have obvious zonation in the vertical direction, which can be divided into three sections of barrier limestone, barrier-skeleton limestone and bonded limestone, which correspond to the colonization- Colonization, colonization and colonization stage.
