Geological characteristics and prospecting potential analysis of Niangniangding Beryllium Deposit on the southern margin of the Jigongshan rock mass
Niangniangding Beryllium Deposit is located on the southern margin of Jigongshan rock mass in Tongbai-Dabie metallogenic belt.The mining area is characterized by the development of Neoproterozoic to Mesozoic intermediate-acid rock mass(dykes),predominantly composed of monzonitic gneiss,biotite granite,and granite.The ore bodies have complex morphologies,generally branching out towards the NW and NEE.On the surface,the ore bodies appear as lenticular shapes,with surrounding rocks comprising biotite monzonitic granite of the Niangniangding rock mass and metamorphic rock strata of Huangmailing rock formation.Based on detailed field investigations,system-atic studies on the geological characteristics,ore-controlling conditions,prospecting indicators,mineralogy,and minera-graghy of Niangniangding Beryllium Deposit were conducted.Integrating previous research results,the genesis of the deposit was explored,a metallogenic model was constructed,metallogenic regularities were summarized,and prospec-ting directions were clarified,providing theoretical support for future exploration.
