Suspended particulate barite crystals were detected in the water columns at four different stations near the 90°E ridge in the Indian *** distinct morphological types of marine barites were distinguished:euhedral-subhedral crystals,oval or round crystals,rhombic crystals,and irregular *** barite crystals in the study area are typically fine,with a dominant size of 1–3μ*** vertical distribution of barites is significantly affected by the formation and sedimentation *** begin to appear at a depth of 30 m and are formed primarily from the surface to the depth of 2000m with a concentration peak at the depth of 200m,where particles are coarser than those in the other *** barites begin to settle and dissolve once formed in the water column,resulting in finer barite particles and lower particle *** formation of barite crystals is related to biological processes associated with the decomposition of barium-rich skeletons in the microenvironment of decaying organic matter that is affected by the primary productivity and dissolved oxygen content in the water *** dissolving process of barite crystals showed similar variation with the concentration of dissolved barium in ocean water,and the substitution of strontium for barite in crystals promotes the selective dissolution of barite and exerts an important impact on its *** is approximately 33%of barites in the amount and 22%in the concentration to settle to the bottom of the water column compared to that observed in the main barite formation zone.
