Discussion on the relation between diorite-porphyrite dike and tungsten mineralization of Sanjiazi tungsten deposit in Siping of Jilin

Sanjiazi deposit is a skarn scheelite mineral deposit newly found in Northeast China.The dikes developed well in mining area,in which the diorite-porphyrite dike controlled the outcrop of tungsten ore body in space with close relation to tungsten mineralization,which is one of the important indicators for tungsten prospecting in this area.The diorite-porphyrite generated prior to scheelite mineralization.Compared with the trace elements and REE of the dike,granite body and scheelite ore,the conclusion can be drawn that the diorite-porphyrite has similarity with granite body and scheelite ore in main trace elements contents and comparability in REE contents,and belongs to homologous relationship in origin.
