中文摘要:高松山金矿床是中国人民武装警察部队黄金第一支队在小兴安岭-张广才岭成矿带北段发现的大型浅成低温热液矿床,随着研究的深入,发现其具有优越的成矿地质条件和良好的找矿前景。在总结前人成果的基础上,文章利用分形学理论对金矿资源量和品位进行了分析,结果显示资源量在大于250 kg标度区间时,分维数D值为1.69,表明资源量在该区段内的普查存在较好的前景,同时,品位分维数D值为1.10~1.40时,其成矿仅与细脉状烟灰色石英-细粒黄铁矿成矿阶段紧密相关。利用钻孔资料分析品位在垂向上的分形特征发现,分维数D值介于1~1.5时,表现为垂向不圈闭延伸,反映其深部可能存在隐伏矿体。在资源评价方面,通过对断裂构造似等距控矿规律的研究,结合帕累托定律（Pareto law）和阻尼曲线模型,对深部可能存在的矿体规模和部位进行了预测,资源量大于4960 kg的矿体仍有2处未发现,中等资源量规模的矿体存在巨大空间,同时,预测隐伏矿体可能在已有地表矿体相间部位的深部。
Abstract:The Gaosongshan gold deposit, recently discovered by Gold Geological Party of CAPF, is a large-size epithermal gold deposit in the northern Xiao Hinggan Mountai ns-Zhangguangcail Mountain metallogenic belt. Deepening studies have revealed that it has superior metallogenic conditions and good ore-search prospect. Based on summarizing previous researches, the authors used the fractal theory to analyz eresource quantity and grades of ore deposits, and the results show that when the resource quantity lies in the scale interval of more than 250 kg, dimension D=1.69, which shows that there exists great prospect of ore prospecting in this segment; when the grade of fractal dimension D value is within the range of 1.1 0 to 1.40, the mineralization is only related to the ore-forming stage of veinle tash-gray quartz-fine-grained pyrite. The use of drilling data to analyze the grade fractal characteristics in vertical direction revealed that, when the fractal dimension D values are in the range of 1~1.5, there exists vertical exten sional trap, suggesting that the probable existence of a concealed orebody in the depth. In terms of resource evaluation, through the study of the equidistant ore-controlling regularity of the fracture structure in combination with Pareto (Pareto law) and damping curve model, the authors made a prognosis of the size an dlocation of the possibly existent ore body. It is shown that two orebodies whose resource quantity is greater than 4960 kg have not been found, that there exists extensive space for the possible orebody with medium resource quantity, and that the concealed orebody may exist in the depth between the known surface orebodies.
