中文摘要：
应用含量—频数分形方法对广东大宝山矿田不同范围多介质、多比例尺地球化学场进行比较分析研究,认为成矿元素在不同比例尺与介质中呈基本一致的复杂多重分形特点,该特点是区域元素形成规模矿的一个必要条件,但不是充分条件;提出成矿元素连续多重分形的分维值减小转折点所代表的局部异常样品数所占比例在各比例尺采样介质中均大于2%,而非成矿元素该比例值可能远小于1%;拟合精度明显影响含量—频数分形曲线的类型与性质。
英文摘要：
In this paper,a comparative analysis of content-frequency fractal method was conducted for multi-range,multi-scale and multi-media geochemical field in the Dabaoshan orefield,It is proposed that the ore-forming elements with different dimensions and media basically show the same complex multifractal features,which is the necessary condition for elements to form the large-scale mineral deposit,but not a sufficient condition. The authors hold that the proportion of local anomaly number of samples accounting for all of the samples of ore-forming elements will be exclusively more than 2% reflected in the multi medium-scale data,the proportion is represented by the turning point of the value of continuous multi fractal dimension decrease,but the proportion of the value of elements without causing mineralization may be by far less than 1%. Fitting accuracy significantly influences the understanding of the type and properties of the content-frequency fractal curve.
