您要查找的是不是：
- During transgressive periods,gravity flow is dominated by calcarenaceous clastic flow and its recomposed sand deposit. 海侵期重力流以钙屑碎屑流及其再改造砂沉积为主；
- Gas layers of calcarenaceous sandstone are closely related to its diagenesis, which belong to diagenetic trap. 本区钙屑砂岩气层与所经历成岩作用密切相关，属于成岩圈闭型气层。
- Prediction of the favorable blocks and the calcarenaceous sandstone reservoir characteristics of Upper Triassic in middle section of the West Sichuan depression 川西坳陷中段须四段钙屑砂岩储层特征及有利区块预测
- calcarenaceous sandstone 钙屑砂岩
- orthoquartzite 正石英岩
- Grey Orthoquartziten. 灰色正石英岩(沉积岩)
