Abstract Chlorite, an Fe-and Mg-rich aluminosilicate clay, may be either detrital or authigenic
in sandstones. Detrital chlorite includes mineral grains, components of lithic grain, matrix …

The tight sandstones are characterized by low porosity, low permeability, complex pore
structure and strong heterogeneity due to the extensive diagenetic modifications they …

Abstract The Mars Science Laboratory Curiosity rover has been traversing strata at the base
of Aeolis Mons (informally known as Mount Sharp) since September 2014. The Murray …

Authigenic clays and calcite cements are important in the development of reservoir tightness
and the formation of hydrocarbon sweet spots. We investigated Jurassic low-permeability …

Heterogeneity is an essential feature of tight sandstones because it is directly related to
reservoir quality. The Upper Triassic Xujiahe Formation in the Sichuan Basin was used as a …

The deep siliciclastic reservoir (> 3500 m) of the Upper Cape Hay Formation of the
Bonaparte Basin (Petrel gas field, Petrel sub-basin, Permian) exhibits wide heterogeneity in …

Middle to late Triassic strata exposed at Edgeøya, eastern Svalbard, represents an uplifted
part of the northwestern corner of the Barents Sea. This interval is characterized by a …

Primary depositional variations interact with diagenetic modifications to exert strong control
on pore networks in tight hydrocarbon reservoirs. However, the linkage between pore …

Lower Cretaceous deltaic sandstones of the Scotian Basin, offshore eastern Canada, are
important gas reservoirs. The influence of several factors on diagenesis has been …

鄂尔多斯盆地西北部华池-环河组赋矿层中存在大套的绿色砂岩, 这套绿色砂岩致绿因素至今尚
不清楚. 文章在野外观察的基础上, 利用测色仪对不同颜色的砂岩进行对比研究, 基于CIE1976 …
