Abstract In the Transdanubian Range (Hungary), a wide spectrum of Triassic dolomites is known. Mechanism dolomitization platform carbonate successions was subject number studies but study basinal carbonates very limited. Petrographical and isotope–geochemical characteristics Upper dolomitized deposits, formed in fault-controlled intraplatform basin, interpretation dolomite-forming processes are...

The meteoric water has obviously changed the physical properties of dolostone reservoirs in vertical vadose zone and horizontal phreatic zone, but its influence on shallow burial beneath surface is still unclear. This study aims to reveal effect through X-ray diffraction, cathodoluminescence, C, O, Sr isotope using sample from Majiagou Formation Daniudi gas field, Ordos Basin. diagenesis parage...

Neoproterozoic carbon isotope excursions are commonly attributed to changes in the global fraction of organic burial associated with climate instability and/or oxygenation. Here we show that carbonate sediment deposited during ca. 661 – <651 Ma Cryogenian non-glacial interlude between Sturtian and Marinoan glaciations exhibit lateral offsets carbonate-carbon values from coeval units by as much ...

stylolite networks and their insoluble residues (ir) are among the major concerns and the fundamental controls on the mining and processing of sedimentary decorative stones, largely made from dolomitized limestones. they are mainly used, as natural rock blocks and polished slabs, to construct and decorate floors and walls of buildings and monuments. representative quarries in khur areas, east o...

nakhlak lead mine is located at the nakhlak mountain 55 km ne of anarak town in isfahan province. the mineralogy is simple; galena and barite are the main primary minerals and cerussite is the main secondary mineral. sphalerite, pyrite, chalcopyrite, tetrahedrite-tennantite and acanthite occur as minor and trace mineral inclusions in galena. secondary minerals are anglesite, plattnerite, wulfen...
