Abstract. The change of metallogenic element grade in borehole has strong randomness and nonlinearity. Quantitative analysis of metallogenic element grade distribution is one of the important ways to reveal the degree of mineralization enrichment. Taking Jiama porphyry copper deposit as an example, the distribution structure of Cu grade series in exploration lines 32 and 36 is analyzed by lacunarity method, and this paper discusses the relationship between lacunarity index and mineralization intensity. It is found that both the lacunarity index and parameters of Cu element in different boreholes exist distinction, the higher the mineralization intensity, the smaller the lacunarity index and the smoother the curve, pointing that the high-grade Cu element is more enriched and uniform. The size of lacunarity index and the variation trend of lacunarity curve have a certain indicative effect on mineralization grade.
