摘　　要：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。samples of eight plants were collected from Lanmuchang and Yangjiawan and quantitative analyses were made of the ore-forming elements in the plant ashes.Considering the three principles of the plant indicator for mineral exploration,namely certainty,sensitivity and feasibility,this paper evaluates comprehensively the indicating functions of the eight plants,on the basis of some quantitative indexes such as the relation coefficient between plant ash and ore-forming element,concentration coefficient,etc.It also discusses the relationships between the anomaly of plant ashes and the fault zone,alteration zone mineralization zone and orebody,showing the significance of these plants to the prospecting.
