On the other hand, reactive-transport models depicting dolomitization (temperature range of 40 to 200°C) predicts the formation of two adjacent moving coupled reaction zones (calcite dissolution and dolomite precipitation) with sharp dolomitization front, and generation of >20% of secondary porosity. Due to elevated temperature of …

Dolomite at the Raber site are from knoll reef colonies. DESCRIPTION The lowest stratigraphic unit identifiable at the Raber escarpment is the Hendricks Dolomite of the Burnt Bluff Group. The Hendricks consists of even-bedded dolomites and limestones of a gray to buff color and are slightly argillaceous. The Hendricks Dolomite is very

The gas source of the Dengying Formation was primarily microbial dolomite (Zou et al., 2014a), which has good hydrocarbon generation potential. As it was affected by the strong weathering crustal karstification of the Tongwan movement, dissolution pores dominated the microbial dolomite reservoir space in the Dengying Formation.

In this protocol (), we demonstrate the generation of agarose-solidified (w/w/o) double emulsions (diameter: ∼55 µm, volume: ∼87 pL) building on agarose-solidified (w/o) emulsions (first phase; diameter: ∼40 µm, volume: ∼33.5 pL) that are produced beforehand with the same microfluidic setup.The workflow includes an …

Two dolomite generations formed shortly after the Last Glacial Maximum (~20 kyr BP): dolomite spheroids and matrix dolomite.

The dolomite occurs in lacustrine fine-grained sedimentary rocks in the middle Permian Lucaogou Formation in the Santanghu intracontinental rift basin, north-west China. Dolostones are composed mainly of nano-sized to micron-sized dolomite with a euhedral to subhedral shape and a low degree of cation ordering, and are interlaminated …

Here, the bimetallic carbonate, dolomite, CaMg(CO 3) 2, only releases one unit of CO 2, before forming more stable CaCO 3, which will not decompose until temperatures >800 °C.. Dolomite offers a thermodynamic stabilisation in comparison to MgCO 3, where the carbon dioxide is released at a higher temperature from the bimetallic material.Conveniently, …

Using our innovative flow focusing methods users can reliably produce water-in-oil (w/o) or oil-in-water (o/w) droplets, made from one, two or three reagents. Our systems are designed to produce ...

In most organic-rich shale reservoirs, dolomite is widely distributed and has different types and crystal sizes. However, the characteristics and formation mechanism of the dolomites in organic-rich shale are still poorly understood. Petrographic and geochemical analyses were performed to interpret the formation of dolomite in the lacustrine organic …

Petrological characteristics. There are mainly two types of dolomites in the Qixia Formation of the study area, namely limy dolomite and granular dolomite, the latter of which can be further classified into silty dolomite (0.005–0.1 mm), fine-grained dolomite (0.1–0.25 mm), medium-grained dolomite (0.25–0.5 mm), and coarse-grained dolomite …

Dolomite was first described in 1791 as a rock by Deodat de Dolomieu, who investigated samples from the Italian Alps. Dolomites are of special interest because they often form hydrocarbon reservoir rocks. Despite intensive research for more than 200 years, the origin of dolomites is subject to considerable controversy.

Dolomite is a sedimentary rock primarily utilized in building and road construction work [40,41,42]. The industrial production of dolomite stone results in a large quantity of waste generation (Fig. 1), which remains dumped at various quarries [43, 44]. A rigorous environmental hazard possesses due to the ineffective and deficient disposal of ...

Multiple episodes of dolomitization of the shallow marine carbonates of the Late Kingriali Formation resulted in regional scale mappable dolostone geobodies in the Kohat and Potwar sub-basins. With the exception of few unaltered patches of the host limestone, more than 90% of the carbonates of the studied formation are diagenetically …

Naming and Discovery. The earliest description of dolomite is attributed to Carl Linnaeus is 1768, but the first meaningful descriptions were presented by the French geologist Déodat Gratet de Dolomieu (1750-1801), who is known to have recorded them from buildings in Rome circa 1791, and collected samples from the Alps in northern Italy. …
