Introduction. According to their textural and geochemical similarity it was suggested previously that the lunar meteorite NWA 4734 could be launch paired with Antarctic Mare basalts (LAP 02205/224/226/436-03632-04841) themselves possibly paired with NWA 032/470 lunar meteorites despite their different textures (1-5). A possible clue about the pairing issue is evidently their age. Method : After...

The Guangshigou deposit is the largest pegmatite-type uranium in Shangdan domain of North Qinling Orogenic Belt, which characterized by enrichment uraninite hosted biotite granitic pegmatites. At Guangshigou, commonly occurs as mineral inclusions quartz, K-feldspar and or interstices these rock-forming minerals with magmatic characteristics (e.g., U/Th < 100, high ThO2, Y2O3 REE2O3 contents ...
