Wenquan porphyry molybdenum deposit of West Qinling is located in northwestern Caledonian fold belt of North Qinling. The identification of polished section and slides��X--diffraction analysis��chemical total analysis of rocks and minerals and REE analysis show that molybdenite��pyrite and chalcopyrite mineralizations in quartz vein are the main types of mineralization in the deposit; while silicification��laumontite and red argillation are the main types of wall-rock alteration. According to the characteristics of deposit geology��wall-rock alteration and geochemistry�� the wall-rock alteration can be divided into three zones��including brick red zeolitization ( grade��)�� strong silification (grade��) and weak silification (grade��)��in which the grade��and �� zones are the main indicators for prospecting.
