Geological characteristics and prospecting potential of Huangniuping beryllium deposit in Jiulong of West Sichuan

Through the comprehensive geological survey in Sanchahe area of Jiulong, Western Sichuan, the authors found that there was a good beryllium mineralization belt near the contact zone between Qiaopengzi rock mass and Triassic surrounding rocks. Four beryllium ore bodies were initially identified in NNW direction, extending along the contact zone of the rock mass. BeO grade can reach up to 0.698%, and the preliminarily predicted BeO resources can be of large scale. The ore mineral is mainly beryl, and the main surrounding rock alteration is tourmaline alteration. The top of the granite mass is also an important metallogenic location of the pegmatite-bearing rock. Remote sensing technology was used in the field of ore prospecting to recognize anomalies, and then large-scale recourse on remote sensing anomalies were carried out. Besides, further engineering methods were used for verification. The results show that the lithium and beryllium anomalies of water sediments in Jiulong area are high, with high matching degree of regional geological conditions. On the periphery of the study area, there is Daqianggou lithium-beryllium deposit in the east, and in the south a large number of spodumene-bearing pegmatites were traced in Wulaxi area, indicating that this area has good metallogenic conditions and prospecting potential.
