The conservation of weathered historic sandstone with apatite was studied.Based on the growth mechanism of bone,calcium and phosphorus were introduced into weathered sandstone and then mineralized at room temperature....
By using the integrated methods includingsandbodies modelling of the outcrops, sedimentary facies ofthe cores and well logs of the drilled wells, and the reservoircorrelation of interwells, it is thought that the sand...
The mega_thick oil_bearing sandstone has been discovered in the Jurassic System in the Tula Basin, among which there are asphalt veins in fractures. The crude oil from oil_bearing sandstone and asphalt in the basin is...
The chemical composition of sedimentary rocks is mainly controlled by source rocks. Through examining chemical composition of terrigenous rocks, the tectonic evolution of a sedimentary basin can be modeled. The Turpan...
The sedimentary rock has a very complex pore structure. Since the middle of the1980s, researches into pore space structure of sandstone show that the pore space ofsedimentary rock has statistical fractal or self-simil...
Kezilesu Group of the Lower Cretaceous located along the belt of Wuqia-Wuyitakein the Southwest Depression of Tarim Basin, a sequence as thick as 1000 metres, hadbeen considered as a sediment of lake-shore delta or la...
The measurement and analysis of the texture of sandstone can provide a lot of information and the basis for the palaeocurrent analysis, basin analysis and palaeoenvironmental reconstruction. Sedimentationists have don...
A special type of carbonate rock is discovered near Yinying, Yangquan on the north border of Qinshui coal field. It occurs between. Sijieshi limestone (K2) and Qianshi limestone (K3) in the Taiyuan Formation. The laye...
Along the belt of the Shuanghe colliery on the NW edge of the Jianchuan Basin in NW Yunnan, there is a suite of thickly bedded crystalline limestone. Based on the geological map (1:200,000) done by the Regional Geolog...
