Reactive transport modelling is increasingly deployed to quantitatively evaluate conceptual models of diagenetic processes. However, construction complex systems involves trade-offs between accuracy and simplification. This tension explored for fault-associated dolomitisation by sea water convection in a syn-rift carbonate platform, evaluating the contribution incorporating stratigraphic growth...

Hydrochemical data of karst springs provide valuable insights into the internal hydrodynamical functioning systems and support model structure identification. However, collection high-frequency time series major solute species is limited by analysis costs. In this study, we develop a method to retrieve individual concentration their uncertainty at high temporal resolution for using continuous o...

The paleoenvironment during the Early Cambrian is closely related to accumulation mechanism of organic matter (OM) from Lower black shales. However, remains a controversial issue. Here, we reported lot detailed data sedimentary stratigraphy and geochemistry Yuertusi Formation in Aksu area, Tarim Basin. Yutixi outcrop consists mainly silicalite at base, two sets shales, crystalline dolostone. Ba...

The eastern part of the Adelaide Geosyncline contains well preserved glaciomarine sequences of the Sturtian glaciation (:750–700 Ma) including calcareous or dolomitic siltstone, manganiferous siltstone, dolostone and diamictite units and the associated Braemar ironstone facies. The ironstone facies occurs as matrix to diamictites and as massive to laminated ironstones and comprises abundant Fe ...

Two cap carbonates overlying Cryogenian panglacial deposits are found in North-East Svalbard of which the younger (635 Ma) forms base Ediacaran Period. It is represented by a transgressive succession laminated dolostone, typically around 20 m thick (Member D1), succeeded transitionally similar thickness impure D2). In Spitsbergen, there evidence microbially influenced sediment stabilisation and...

The lower Cambrian Niutitang/Qiongzhusi shale gas in the Middle-Upper Yangtz Block had been regarded as a very promising unconventional natural resource due to its high total organic carbon, great thickness, and large areal distribution. However, no commercial fields have yet reported. From northwest southeast there are considerable differences sedimentary environments, lithology, erosive natur...

Several studies have exploited the stable calcium (Ca) and strontium (Sr) isotope compositions of marine carbonate rocks to investigate ancient carbon cycle dynamics, seawater geochemistry, controls on production preservation. However, two proxies rarely been applied together. Based knowledge achieved date, δ44/40Ca-δ88/86Sr multi-proxy can distinguish signatures imparted by mass-dependent frac...

pb-zn deposits in the kurdistan region, northern iraq, have occurred mainly as a stratabound and open-space filling ore bodies. they are hosted by dolostone and dolomitic-limestone of platform carbonates. the ore deposits at the studied dure and lefan areas are respectively hosted by kurra chine (upper triassic) and bekhme (upper cretaceous) formations. pyrite, sphalerite and galena are the maj...

Multiple episodes of dolomitization the shallow marine carbonates Late Kingriali Formation resulted in regional scale mappable dolostone geobodies Kohat and Potwar sub-basins. With exception few unaltered patches host limestone, more than 90% studied formation are diagenetically altered by replacive dolomites with associated dolomite cementation. Petrographical geochemical data interpretation r...
