| 摘 要： | 通过对高龙金矿鸡公岩矿段各中段金品位数据进行的初步数理统计研究，发现矿化标志X1和t1随着矿体深度的加深而逐渐变小，说明金矿化强度自上而下有逐渐减弱的趋势；变异系数V则随深度的加大逐渐变大，表明向深部金的矿化愈来愈不稳定。这三项参数的变化特征表明，矿化向深部渐弱，最后可能逐渐消失。

| Abstract: | Preliminary statistic study of gold grades data, which are from several levels of Jigongyan ore block of Gaolong gold deposit, indicates that the values of X1 and t1, indexes of mineralization, get smaller and smaller with deepening of ore body. This suggests that intensity of mineralization of gold gradually diminishes from the top down. While variation coefficient V gets greater and greater with deepening of ore body, which suggests that mineralization gets unstable to the depth. The variation of these three parameters indicates that mineralization diminishes with depth. |
