| 摘 要： | 阿克苏露头区多条震旦系地质剖面研究揭示震旦系风化壳古岩溶作用识别标志主要有区域性不整合面、大型洞穴垮塌角砾岩、溶洞、溶孔及高角度溶沟、溶缝等。震旦系风化壳古岩溶垂向分带结构以水平潜流带和深部缓流带为主，垂直渗流带发育较弱或不发育。水平潜流带以发育大型洞穴垮塌堆积体及蜂窝状溶洞群为特征，深部缓流带以发育孤立溶洞为特征。区域古岩溶特征及垂向分带结构对比表明，阿克苏露头区震旦系风化壳古岩溶模式为高潜水面缓坡型古岩溶。 |

| Abstract: | Study on several Sinian outcrop sections in Aksu area indicates that unconformity, large cave collapse breccias, solution caves, solution pores, solution fissures and grooves should be the identifying features of Sinian paleo-karstification. Horizone-phreatic zone and deep-slow-flowing zone are the main parts of the karst vertical zonation. Large cave congeries and honeycomb formation caves are significant evidences of horizone-phreatic zone. The characteristic of deep-slow-flowing zone is isolated caves which are always associated with the fractures. The paleo-karst model of Sinian is higher-phreatic gentle-slope paleo-karst. |
