Lujing uranium ore deposit is located in the NS-EW inward depression turning of the Wanyang-Zhuguangshan composite body. This deposit has the most important representative significance and research value in the Lujing uranium ore field because of its granites interbelt-type and exobelt-type. We carry out comprehensive geological investigation
sampling
slice identification and major element that based on the previous publications. Lilhologically
this pluton is consisted mainly of medium-coarse porphyroid biotite adamellite. The major elements are characterized by rich-silicon(average value of Si O2 is 76.51%)
rich-alumina( A/CNK average value is 1.25) and high ω(K2O)/ω(Na2O)( 1.99 on average). The Indosinian granite of Lujing deposit is belong to the series of peraluminous
