摘要
庞西垌—金山银金成矿带位于广东廉江县和广西博白县的交界，区内银金矿床以银为主，伴有金、铅锌等有益组分，属于蚀变破碎岩型银金矿床。研究表明，银金矿床具有明显的分形性，利用品位－频度的双对数坐标图求得的矿床银品位的分维值Ｄ＜１，反映了在区域内银品位分布的差异较大，银品位的频率分布明显偏离正态分布。利用储量－分形模型对区内银的储量进行了预测，证实该方法具有较高的可靠性和良好的适宜性。
The
Pangxidong Jinshan silver gold deposit, located in the border area between Guangdong and
Guangxi, is a silver deposit associated with Au, Pb and Zn, belonging to alteration rock type.
The fractal dimension of silver grade frequency of the ore deposit shows the spatial
distribution and change of silver grade in the orebody. The fractal dimension D <1 indicates
remarkable change in spatial distribution and obvious deviation from the normal distribution of
Ag grade. Using silver grade reserve fractal mineralization pattern, one can foreast the
possible silver reserves in the mining area. The forecast result shows that the area has
promising resource potential, and the grade reserve fractal mineralization pattern is reliable
and suitable for ore prospecting in this area.
