| 摘 要： | 在简要介绍变差函数的原理、算法和研究区地质情况的基础上,将变差函数引入火山岩型铀成矿作用与地形相关性研究中。详细描述了赣杭构造带中不同成矿规模矿田(床)区地形高程变差统计的过程,初步分析了变差统计结果的地质意义。研究结果表明,地形高程值变差函数的长轴方向可以反映研究区的主要构造方向,变差函数的长短轴半径与铀矿床的成矿规模在一定程度上具有对应关系。

| Abstract: | Based on a brief introduction of principle,algorithm of variogram and the geological condition of study area,variogram was introduced into the correlation study of volcanic type uranium mineralization and terrain.The process of caculating variogram of terrain elevation where uranium deposits（orefield）with different scales occur in Gan-Hang Tectonic Belt was described in detail.The geological significance of variogram statistics was preliminarily analyzed.The results show that the long axis direction of variogram of terrain elevation could reflect the main structure direction of study area,while the radius of long axis and short axis of variogram are consistent with uranium mineralization scales in a certain extent. |

| Keywords: | variogram terrain correlation quantification structure direction mineralization scales |
