Abundant metal mineral resources are hosted in the Early Cambrian black rock series at periphery of Yangtze platform in China.Geological features and problems related to mineralization of vanadium deposits in the black rock series are studied in the paper.The vanadium deposits are horizontally controlled.Vanadium and other metal mineralization is related to a variety of deposition conditions.Epoch of alternated hydrothermal deposition and normal sedimentation is the peak epoch for the mineralization of vanadium.The metallogenic age of ores is(521±54) to(542±11)Ma.Genetically,they are sedimentary deposits.
