Main Component

Huashan granite-type uranium ore deposit is originated within the Huashan granite pluton in northeast of Guangxi, the mineral (mineralization) occurrences already found include Changchong, Baishijiao and Caomiping. Previous studies are relatively weak, especially in mineralogical characteristics, in this paper, a detailed study of minerals has been carried out through EPMA and EDS, the results show that the uranium mineral compositions of the three mineral (mineralization) occurrences are significantly different, but all of them are of secondary uranium minerals, among them, the main component of Changchong mineral (mineralization) occurrence is (meta-) autunite, of Baijiaoshi mineral (mineralization) occurrence is kasolite, and of Caomiping mineral (mineralization) occurrence is torbernite and zeunerite, which reflect the difference of their minerals sources.

Uranium Mineral

Rumours of Iuminosity having been observed in Cornish minerals, in the dark, are not infrequent. I have myself been told of such phenomena by rustics in the mining district, and more than one correspondent has mentioned something similar. None of the accounts have, however, been sufficiently precise to carry convicition, or to afford much clue for further investigation. They have in many cases been obviously exaggerated. Mr. F. W. Rudler has quoted a remark by the late Mr. Garby that specimens of uranite " when first discovered by the miners in Huel Buller and Huel Basset were very phosphorescent, so much so that after the lights were extinguished many of the crystals might be discovered in situ " and he has suggested that this may be in some way connected with the self luminosity of radio-active bodies. The observation would seem to have been made by the miners, not by a scientific observer, and it is implied that the luminosity was of the nature ordinary phosphorescence, and due to previous exposure to light.
