strate that barite crystals with similar morphologies and sizes as marine barite found in seawater and marine sediments (Dehairs et al.,1980; Griffith and Paytan, 2012) can precipitate in an abiotic process through the replacement of amorphous Ba-P phases obtained from both organic and inorganic P com-pounds in a sulfate-bearing media.

Barite is a solid mineral that combines barium and sulphur. It is composed of barium sulfate (BaSO 4) (Arrifan, 2003; Brock-Hon and Johnston, 2014; Ehya and Mazraei, 2017; Ene et al., 2012; Robin et al., 2003; Tanko et al., 2015).Barite appears in nature as granular or crystalline masses, nodules, rosette-like aggregates and also in laminated to massive beds of …

The accumulation rate of authigenic barite (BaSO 4) in marine sediments is a promising proxy for reconstructing marine export production, but many aspects of barite precipitation and dissolution in the water column …

API barite was easy to settle down, and under a certain pressure difference, mud cake could be quickly formed which decreased the filtration volume (Fig. 8). API barite/WBDFs showed a bimodal distribution (Fig. 10 and Table 4) which contributed to the less filtration loss. The particle size distribution of mMB/WBDFs showed a unimodal peak.

The Niederschlag fluorite-barite vein deposit in the Western Erzgebirge, Germany, has been actively mined since 2013. We present the results of a first comprehensive study of the mineralogy, petrography, fluid inclusions, and trace element geochemistry of fluorite related to the Niederschlag deposit. Two different stages of fluorite mineralization are recognized. Stage I …

Barite scale is the most common oilfield scale in oil and gas wells. Barite scale removal still represents a challenge to the oil and gas industry because of its low solubility in mineral acids such as HCl. Chelating agents such as diethylene triamine pent acetic acid (DTPA), ethylene diamine tetra acetic acid (EDTA), and hydroxy ethyl ethylene tri acetic acid were …
