Ts. Sunilkumar et al., ASSOCIATION OF AUTHIGENIC APATITE WITH URANIFEROUS ORGANIC-MATTER AT DOMIASIAT, MEGHALAYA AND ITS GENETIC-IMPLICATIONS, Journal of the Geological Society of India, 48(4), 1996, pp. 409-414
The occurrence of authigenic apatite with uraninite, pyrite, sphalerit
e and galena within organic matter is a characteristic feature of the
sandstone-type uranium deposit at Domiasiat, Meghalaya. Apatite occurs
in the form of thin hexagonal basal plates and its identification is
confirmed by x-ray diffraction. The authigenic apatite in this specifi
c association points towards diagenesis in euxenic conditions of marin
e affinity.
