摘要
对大兴安岭古利库金(银)矿床的不同类型矿体(矿化围岩)和不同深度区间岩心样品的Au、Ag、Au/Ag的变化特征研究表明:由最北部的矿(化)体至最南部的矿(化)体,金银比值在水平10000m范围内降低约97%,而0～200m不同深度区间内岩心样品的Au/Ag平均比值稳定变化在0.08～0.09之间,即矿区由北至南出现明显的金银矿化的水平分带,而未出现金银矿化的垂向分带.
Guliku gold (-silver) deposit is located at the connection of Dayangshu volcanic basin and Luomahu intermediate uplift.Based on the study of Au and Ag composition and Au/Ag ratio in ore body and mineralized wall rock,the value of Au/Ag decreased by 97%in a width of 10000 m from the northern to the southern ore bodies,but is almost free from change between 0.08 and 0.09 in the depth of 0 to 200 m.So there is a horizontal rather than a vertical gold silver mineralizing zonation in Guliku deposit.
