| 摘 要： | 布露于藏北羌塘才玛尔错一带的一套碳酸盐岩夹碎屑岩,对其时代归属由于缺乏可靠的古生物化石,一直颇有争议。通过对此套地层详细的剖面研究表明其时代属晚三叠世,其沉积环境为斜坡—盆地,与区域同时代台型沉积的肖茶卡组、日干配错组沉积环境有明显的差异。此套地层时代厘定为研究羌塘地块地质构造演化提供了重要的基础地质资料。

| Abstract: | A set of carbonatite intercalated with fragmental rocks unveils over the area of Caimarcuo, Qiangtang, which is due to lack of reliable bioclastic fossils controversial at all times. Detail profile studies on this suit of strata indicate its age falls in the Upper Triassic, the sedimentary environment that is slope basin distinctly differ from the regionally-contemporary platform-type sedimentary environment of the Xiaochaka Formation and Riganpeicuo Formation. Determination of the set of the strata provides significant information of foundational geology in order to investigate structural evolution of the Qiangtang massif. |
