在不列颠哥伦比亚西部和中部三个较大的钼矿山(爱丽斯湾、恩达可和貝尔格)进行了岩石地球化学研究。目的是观察不同气候条件下钼的表生氧化和递减的程度。爱丽斯湾钼矿位于温哥华西北490英里,爱丽斯海湾以南约6英里处,海拔2000英尺,年沉积量超过100英寸。矿床产于一个直径约0.5英里的花岗岩类杂岩岩株中。该岩株由石英二长斑岩中心带组成,逐渐过渡到石英闪长岩边缘带。岩株的周围可能是侏罗系杂砂岩和泥质板岩。近岩株的杂砂岩和泥质板岩变质为黑云母角页岩。矿体分布在岩株的周围或靠近黑云
Petrological and geochemical studies were conducted at the three larger molybdenum mines in the western and central British Columbia (Alice Bay, Ndakov and Berger). The purpose is to observe the degree of epigenetic oxidation and decay of molybdenum under different climatic conditions. The Alice Bay molybdenum mine is located 490 miles northwest of Vancouver and about 6 miles south of Alice Cove at 2000 feet above sea level with an annual deposit of more than 100 inches. The deposit was produced in a granite-type complex rock about 0.5 miles in diameter. The rock is composed of quartz diopside central zone, gradually transition to the edge of the quartz diorite zone. The rocks may be surrounded by Jurassic and argillaceous slate. Miscellaneous rocks and shale slate near metamorphic rocks are biotite horn shale. Ore bodies are distributed around or close to black clouds
