摘要
MARGIN: auto 0cm" class=MsoNormal>man’,’serif’" lang=EN-US>The Donggebi Molybdenum deposit in the East Tianshan Orogenic Belt belongs to porphyry type. The shape of orebodies is restricted to the shape, size and rockbody, physical nature of surrounding rocks and growth degree of sub-fracture. The mineralization has no choice of surrounding rocks, which is related to sub-fracture density formed by more periodical structure activities. The Mo mineralization is related to surrounding rocks alteration. Evolution of the alteration may be divided into five stages, of which mineralization-alteration stage of molybdenite-quartz is the principal mineralization period.mas-microsoft-com:office:office" />
