中文摘要:本文在研究361铀矿床碱质交代、蚀变花岗岩特征的基础上，阐明了本区花岗岩的后期多次改造，并指出了各碱质交代、蚀变在铀成矿过程中的作用，以及它所造成的岩石分带性。同时，也计算了各铀源体的浸出率，指出铀主要来自赋矿围岩——γ51-1和δγ51-2花岗岩。

Characteristics of granites and sources of uranium in no.316 uranium deposit
Abstract:Besed On a study of alkali metasomatism and alteration of granites in No．36l uranium deposit, the authors point out in this paper that granites in this area have experienced multiphase post-diagenetic reformation;they also describe the role of various sorts of alkali metasomatism and alteration in mobilization, transfer and enrichment of uranium during the ore-forming process and the metasomatic and alteration zonation of rocks that resulted from these activities. The leaching ratios of various granitic uranium sources and the amounts of uranium they could respectively provide were calculated.These data combined with REE analyses suggest that ura nium was mainly derived from host rock-γ51-1 andδγ51-2 granites.
