Carbonate concretions provide unique records of ancient biogeochemical processes in
marine sediments, and have the potential to reflect seawater chemistry indirectly. In fine …

Spherical carbonate concretions are present in sedimentary strata of varying geological
ages worldwide. Recent studies reveal that calcium carbonate concretions form very rapidly …

Mineralogical and textural characteristics and organic carbon composition of the carbonate
concretions from the upper Doushantuo Formation (ca. 551 Ma) in the eastern Yangtze …

The development of carbonate factories has potential importance in studies of
paleoenvironment, sedimentology, and reservoir geology, but the mechanisms controlling …

The formation of carbonate concretions is a cementation process which passively infills the
pore spaces within sediments. They record the original environments of deposition and …

Carbonate cementation of sandstones at channel bases is commonly interpreted to be a
result of solutes generated from surrounding rocks in a burial-diagenetic regime. However …

Lacustrine carbonates are widely distributed in the third member of the Eocene Shahejie
Formation (Es 3 L) of the Shulu sag and other rift basins in the Bohai Bay Basin, which can …

Authigenic carbonate chemistry and mineralogy provide key insights into diagenetic
pathways and microbial processes in sedimentary records. We characterize the mineralogy …

The Eocene Es4s interval is an important petroleum reservoir of sublacustrine fan
dominated at the depths of 2500–4000 m in Dongying depression, Bohai Bay basin. Based …

The characteristics and formation mechanism of calcite cements in the tight sandstone of the
Jurassic Lianggaoshan Formation in the northeastern Central Sichuan Basin were analysed …
