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 …

In the porphyry Cu±Au±Mo deposits (PCDs), chlorite and its mineral assemblages are
indicators for exploration. However, chlorite found in PCDs may have different origins …

Chlorite coats are widely recognized as a key element in preserving sandstone porosity
because it can inhibit the growth of quartz cements. However, the alteration of chlorite coats …

Authigenic chlorite plays an important controlling role in reservoir quality, and is widely
distributed in the tight sandstone reservoirs of the Triassic Yanchang Formation in the …

Abstract The upper Permian Shiqianfeng sandstones, located in the Dongpu Depression,
Bohai Bay Basin, China, are fluvio-lacustrine deposits and have high content of pore-filling …

Clay coats are widespread in the Oligocene braided river channel sandstones in the Xihu
Depression on the East China Sea Shelf Basin. High clay coat coverage in braided channel …

The tight oil sandstone reservoir of the Upper Triassic Yanchang Formation is one of the
main targets for hydrocarbon exploration in the Ordos Basin, China. Sandstones of the …

The verdine facies clay assemblages are regularly encountered in shallow marine
sediments of equatorial latitudes where Fe of terrigenous origin is readily available. There …

在西湖凹陷花港组储层整体低渗的背景下, 优质储层的发育往往伴随绿泥石的富集.
通过薄片观察, X 衍射分析和扫描电镜及能谱分析等研究, 认为研究区绿泥石呈黏土包膜 …

The characteristics of diagenetic minerals and their effects on reservoir quality of the tight
sandstones of the Permian in Sulige gas field of the Ordos Basin were studied through …
