Barite formation in the ocean: Origin of amorphous and ...
2019-4-20 Mineralogical and crystallographic features of these precipitates have provided new insights into this formation process: i) the evolution from Ba-phosphate to Ba-sulfate (i.e., barite) is evidenced by the compositional range identified; ii) the Ba-phosphate precursor is amorphous, and it evolves to crystalline barite; iii) barite itself in ...

The Formation Process Of Muscovite Mica
2019-1-14 Muscovite Mica is one of a wide range of rock-forming minerals and is produced in all three major rock types.Mud-like rocks can form Sericite Mica during metamorphism in low-level areas, and become muscovite when the degree of metamorphism is slightly higher. A large amount of muscovite is formed in the late stage of acid magma crystallization and in the stage of pegmatite.

Formation Damage due to Drilling and Fracturing Fluids
Once the drilling process is accomplished, hydraulic fracturing is commonly used to stimulate the reservoir; this process can also cause formation damage. During the fracturing, a large volume of proppants is carried into the reservoir by the fracturing fluid, and this is aimed at creating a complex and highly conductive fracture network [15, 16].

Precipitation of barite by marine bacteria: A possible ...
2012-8-1 Barite (BaSO 4) is found throughout the ocean, yet seawater is undersaturated with respect to barite, and organisms that could account for the abundance of barite have not yet been identified.The mechanism for barite formation in seawater is not fully understood. Here we show that marine bacteria have the ability to precipitate barite through a metabolically mediated biomineralization process.
