【Abstract】 Native aluminum was discovered in quartz dioritic porphyrite and altered quartz sandstone in theLianhuashan tungsten mining district. It has an irregular grain shape, usually 0.2-0.04mm in size andwhite in colour, and occurs as impregnation ore in gangue minerals. The alumiunm content of the Lianhuashan W-deposit area is lower than those of previous discoveries.更多还原
