Crystal System: Orthorhombic
Specific gravity: 7.695 calculated
Environments
Orishchinite is a new mineral, approved in 2019 and to date (October 2022) reported only from the type locality.
Localities
At the type locality, the Daba-Siwaqa complex, Transjordan Plateau, Amman Governorate, Jordan, orishchinite was
found in a paralava, which in this case was formed from the melting of
marble and phosphorites.
The host rock is part of the Hartrurim Formation and is one of the largest complexes of the sedimentary strata know to
have experienced combustion metamorphism. The melting likely occurred during the natural combustion of bituminous
shales or natural gases that are common in the area. To date (October 2022)
there is no scientific consensus as to the cause of the fire
(AM 107.1983).
