7. Conclusions
- (1)
- The U–rich granitic pegmatites were formed in the late Paleoproterozoic (1826.3 ± 7.9 and 1829 ± 11 Ma). The paragenetic phenomena of the magmatic zircons with betafite and uraninite in the samples showed metallogenic characteristics during the crystallization period.
- (2)
- Based on the classification criteria and rock characteristics of A–type granite, the major elements, trace elements, and mineral compositions of most U–rich granitic pegmatite samples had the characteristics of intraplate A1–type granite
- (3)
- The U–rich granitic pegmatites were formed after the Luliang movement in the late Paleoproterozoic, and the tectonic system gradually transitioned from a continent–continent collision to an extensional setting. The partial melting of the early Taihua group materials formed in the Archean–Neoarchean period triggered a series of tectonic granitic magmatic activities.
- (4)
- The early Taihua group formed in the Archean–Neoarchean period as mature crust material rich in uranium, which provided uranium–rich magma for the formation of uranium–rich granite pegmatite in the late Paleoproterozoic. Existing uranium–rich geological bodies also provided material sources for later uranium mineralization in the Huayangchuan deposit.
