在滥木厂和杨家湾铊 (汞 )矿床 (点 )对芒箕、南烛、榔榆、大金发藓、蜈蚣草、石松、黄花草、醉鱼草等 8种植物取样 1 45件 ,在提出确定找矿有效指示植物三原则 (确定性 ,敏感性 ,可行性 )的基础上 ,依据植物灰分与底质成矿元素相关系数、植物灰分富集系数和衬度系数 ,较全面地分析和评价了 8种植物的找矿功能 ;讨论了其异常的分布与断裂带、蚀变带、矿化带以及工业矿化 (矿体 )之间的关系 ,并指出了其找矿意义。
A total of 1 45 specimens of 8 species of plants such as M. przewalskii, S. cunicailles, Cannabis sanguinuensis, Betula platyphylla, Pteris vittata, Lycopodium pumila, Based on the three principles (deterministic, sensitivity and feasibility) of determining the effective indication of prospecting for ore deposits, based on the correlation coefficient between plant ash and sediment mineralization elements, the enrichment coefficient and contrast coefficient of plant ash, a more comprehensive analysis And evaluated the prospecting functions of 8 species of plants. The relationship between their anomalous distribution and fault zone, alteration zone, mineralization zone and industrial mineralization (ore body) was discussed and its prospecting significance was pointed out.
