| 摘 要： | 结合陕西灞源地区金矿预测实例,探讨了在蒙特卡罗法应用中潜在矿床总数估计及资源总量概率分布向资源潜力分布转换两个环节的合理实现方法。在一定条件下,矿点空间分布模型和发现过程模型可有效地用于估计潜在矿床总数。通过坐标平移或求截尾分布而将资源总量的概率分布转变为资源潜力的概率分布,可得到较为符合地质实际的评价结果。

| Abstract: | By using the calculating examples of gold endowment and resource potentiality of the Bayuan area, Shaanxi Province, this paper inquires two important problems concerning the application of the Monte-Carlo method: one is the estimation of the number of potential deposits , and the other is the calculation of resource potentiality from metal endowment. Under certain circumstances an ore occurrence spatial model and a discovery process model can be employed to tackle the first problem effectively. By translating the coordinates of the probability distribution for metal endowment, or by calculating its truncated form, a geologically feasible probability distribution for resource potentiality can be obtained. |
