摘要
西秦岭地区是我国重要的金成矿区带之一,甘南早子沟金矿位于西秦岭西端,发现于1996年。近年来随着勘查程度的不断加大,矿区资源量有很大幅度的增加,目前提交资源量已达52.8t,本文通过单因素直方图统计、曲线拟合、分形统计等方法研究了矿区矿体资源量变化的规律与关系,通过不同函数拟合品位—吨位关系,幂函数分布的品位—吨位模式更好地反映了矿区品位—吨位关系,运用分形理论解释了矿体资源量与品位之间的关系,认为矿体资源量是各阶段矿体资源量的线性叠加。并对分维数D值的地质意义进行了阐述。
Zaozigou gold depositis located in the western part of west Qinling. With the exploration progress in recent years, the gold resource has reached 52.8 tons now. The authors studied the relations between the variation and relative parameters of orebodies＂ resource by means of the single-factor histogram statistics, curve fitting, fractal statistics. By comparison of fitting curves separately made by power function and exponential function, the power function model is better to reflect the relation of grade and tonnage. According to fractal theory, it is supposed that the orebody resource maybe the linear superposition from 3 mineralization phrases.
