矿床规模频率法在铀资源评价中的应用和效果初探

DISCUSSION ON THE APPLICATION AND RESULTS OF DEPOSIT-SIZE-FREQUENCY METHOD IN URANIUM RESOURCE EVALUATION

矿床规模频率法(DSF)是由美国数学地质博士R.B.McCammon和地质专家W.J.Finch等开发并新近引入我国的矿产资源评价方法。该方法具有快速而更加准确地估算未发现矿产资源量的特点。作者在我国西北某铀成矿区采用该方法进行铀资源评价的具体实践,介绍了方法应用中有关计算方程各种因子的选用等问题,同时,对方法的应用效果、各种因子取值对计算结果的影响等进行了初步分析和探讨。

The Deposit-Size-Frequency (DSF) method was developed by American mathematical geologist Dr. R. B. Mc Cammon and research geologist W. J. Finch. It is a method of mineral resource evaluation recently introduced into China and characterized by rapid and more accurate estimation of undiscovered endowment. Adopting this method, the author evaluated the uranium resources in a certain uranium metallogenic province in northwest China and introduced approaches on the selection of various parameters for the calculation equation concerned in the application of the method and at the same time the application results of the method, the effect of various parameter value selecting on the calculation results are preliminarily analysed and discussed.
