The early high-temperature uranium mineralization in Zhusanxia deposit

The early high-temperature uranium mineralization had been discovered from a series of studies about the uranium mineralization in Xiazhuang ore-field. Based on the studies of the geological occurrence and mineral compositions and chemical compositions of the green pneumato-hydrothermal solution of the early high temperature uranium mineralization comes from the granite which age is about 150-155 Ma, and is SCF (Super Critical Flow) of 500 degree C above and rich in K, B, W and U. After altered by the SCF, these diorites has low Na2O, Na2O<K2O and Eu weak loss. The early high-temperature uranium of the area is characterized with the minerals assemblage of uraninite, tourmaline, scheelite and magnetite, and with age of 146-165.5 Ma
