| 摘 要： | 敖瑙达巴斑岩型铜银锡乡金属矿床既不同于大多数由幔源岩浆衍生物所形成的斑岩铜矿,也不同于大多由地壳重熔岩浆衍生物形成的斑岩型锡(钨钼)矿床。它是分布于过渡性地壳上的、由起源于下地壳-上地幔的过渡性岩浆的衍生物形成的斑岩型铜银锡矿床。根据已取得的资料,在矿区内磁法、电法、化探异常的展布与已知矿化蚀变带一致。凡磁、电、化探异常吻合一致的综合异常,经验证都已见到了矿体。

| Abstract: | The Aonaodaba porphyry copper-silver-tin polymotallic deposit is different both from most porphyry copper deposits formed by derivatives of mantle magma and from most porphyry tin (tungsten, molybdenum) deposits produced by derivatives of crustal remelted magma. It is a porphyry copper-silver-tin deposit that occurs in the transitional crust and was formed by derivatives of the lower crustal-upper mantle transitional magma. According to data available, the distribution of magnetic, electrical and geochemical anomalies in the ore district is consistent with the known minsralization-alteration zone. Where there are integrated anomalies formed by consistent magnetic, electrical and geochemical anomalies, there are orebodies revealed by drilling inspection. |
