The Characteristics of Devonian Sedimentary Rocks and Their Sedimentary Environments in the Keziyangluk area, Xinjiang

Institute of Geology, Chinese Academy of Science, Beijing 100029

摘要

摘要: 在西昆仑北带沉积区中，泥盆系沉积是该区古生代最早的沉积层，它超覆在中上元古代沉积层之上。在莫木克以南克兹扬鲁克一带，泥盆纪中上段地层发育较好，颇有代表性。这套沉积层根据岩石组合分为上下两段，下段是一套富含凝灰质的碎屑岩一碳酸盐岩建造。具有重力流的沉积特点。上段是一套陆屑砂砾岩－杂砂岩建造，属于滨海海滩相、滨海近岸三角洲相、河流相沉积。

Abstract: The Devonian strain are developed on the north margin of the West Kunlun Mt. They are the oldest Paleozoic sedimentary rocks in this region and overlapped on the Middle-Upper Proterozoic strata. To the south of Monk, the Middle-Upper Devonian is well developed in the Keziyangluk area.According to the lithological features and rock associations, they can be divided into two members. The lower one is a tuffaceous graywacke carbonate rock formation, composed of tuffaceous graywacke, tuffaceous shale, pebble-bearing sandy slate and carbonate rock. The upper member is a terrigenous sandy conglomerate graywacke formation, composed of conglomerate,sandy conglomerate, lithic graywacke,quartzose graywacke, silstone, etc. The lower member is characterized by laminar bedding and horizontal bedding, indicating a steady hydrodynamic sedimentary environment. The upper member comprises torrigenous sand and Pebble sediments with clear cyclicity. Its different horizons show different sedimentary structures, such as horizontal bedding, various cross-bedding and interference ripple, indicating an unstable sedimentary water body and unsteady sedimentary factes.The studies on sedimentary structures and lithological grain features of the Middle Upper Devonian strata suggest that the lower member is formed in a bathyal-neritic sedimentary environment. and that the upper member is developed in an littoral beach inshore deltufluvial sedimentary environment.
