Barite concretions from the ocean floor
Bulletin of the Geological Society of America (July 1951) 62 (7): 707-723


In 1938, a dredging from the sea floor off California recovered about 6 kilograms of tubular, sub-spherical, flat, and irregular shaped barite concretions embedded in marine mud. These are poorly sorted in weight and size. They range from 1 to 25 centimeters in length. The physical, chemical, and mineralogical characteristics of the nodules are described and compared with those of other barite concretions found on land or dredged from the sea floor. Barium sulphate is present in amounts up to 77 per cent, in the form of small radial aggregates often within the tests of Pliocene Foraminifera.
