Endogenetic uranium ore possesses some different textures from common metal-lic ore. The fact that acicular and prismatic native and synthetic pitchbleude isassociated with spherical pitchblende ih granite type uranium deposits in SouthChina has demonstrated that pitchblende spherules crystallize directly from orefluids. The research on the characteristics of pitchblende spherules indicate thatthe pitchblende sphe?ules are the manifestation of spheroidal crystallization ratherthai the colloid texture as advocated by the traditional view. The micrograinedand micro-dispersed textures are the most common texture for endogenetic uraniumore. The framboidal and petatoid aggregate of synthetic pitchblende indicates theexistence of nonbiogenetic framboidal texture in metallic ore.
