西昆仑地区处于中亚腹地的高寒缺氧地带,区域地质研究程度较低。早志留世轻变质碎屑岩地层时代的确定主要依据三叶虫、头足类和珊瑚等大化石,一直没有微体化石方面的证据。最近,在西昆仑地区进行的地质调查中,在温泉沟地区新发现了较丰富的志留纪Desmochitina,Sphaerochitina,Rhabdochitina,Conochitina等属几丁虫化石,为早志留世碎屑岩地层时代的确定、西昆仑地区地质调查工作的开展、志留纪地层的划分对比和西昆仑地区地质演化历史的研究提供了重要微体化石方面的依据。
Western Kunlun Mountains is located in the Central Asia hinterland of the alpine anoxic zone, regional geological research is low. The stratigraphic ages of the Early Silurian metamorphic clastic rocks are mainly based on the trilobites, cephalopods and corals and other large fossils, there is no evidence of microfossil. Recently, in the geological survey carried out in the western Kunlun Mountains, more abundant Silurianum Desmochitina, Sphaerochitina, Rhabdochitina and Conochitina were found in the Wenquangou area, which are the identification of epochs of the Early Silurian clastic rock , West Kunlun area geological survey work, the division of the Silurian strata and Western Kunlun area geological evolution history provides a basis for important micro-fossils.
