Answer: Both gypsum and halite (rock salt) are evaporites, which means they occur when shallow bodies of water slowly dry out. Imagine a lake or a lagoon that is shallow but has a large surface area and/or in a very hot climate. This body of water will evaporate over time, leaving just a dry bed...
· Few deposits are viable for DAPR as this requires a highly soluble phosphate rock. Of particular note is the Minjingu Phosphate deposit in Minjingu, Tanzania. This site produces the most appropriate phosphate rock for DAPR appliions. Conclusion. Phosphate rock plays a critical role in the nutrient cycle of many soils. Of significant ...
Gypsum deposits enclose Badenian carbonates shown in blue lyon eroded Cretaceous and Jurassic substrate filling in depressions (A. Radwanski, 1969). These marine deposits reach a maximum thickness of 115 m in the Pinczow area (at Mlyny), and only some tens of metres in the Wislica area where the evaporites commonly lie directly on the Cretaceous substrate. The evaporites are over 50 .
· Prokhorenko et al. explored the GPR reflection technique for the detection of caves and galleries in gypsum deposits as well as for searching of discontinuities and cracks in rocks. McCormack et al. ( 2017 ) demonstrated the use of ERT and discrete conduit network modelling to characterize the hydrogeology of the chment by determining flow pathways and their likely hydraulic mechanisms.

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and massive finegrained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including ...

Mining in Tanzania includes metals (gold, iron ore, nickel, copper, cobalt, silver), industrial minerals (diamonds, tanzanite, ruby, garnet, limestone, soda ash, gypsum, salt, phosphate, gravel, sand, dimension stones and lately graphite), and fuel minerals (coal, uranium).Mining and quarrying activities in Tanzania contributed .
Rock Phosphate mines at Jhamarkotra Kanpur Group of Mines are complex deposits. Mining these rock phosphate deposits is far more difficult than that in most parts of the world. Despite the complexities of the deposit, excellent results have been achieved by continuous innovations. With an annual rock handling of about 20 million tonnes, Jhamarkotra is probably the largest open cast mine .
