摘　　要：依据黔西南滥木厂铊 (汞 )矿床地质特征 ,在对与矿化有关的植物组合及其分布特征进行研究的基础上 ,以大金发藓 (PolytrichumCommuneHedw)为例对其进行了地质植物法填图。按 1 2 0× 6 0m布置观察点 ,对其分布密度进行统计 ,编制密度等值线图 ,讨论了密度等值线展布方向和不同密度等值线分布区与北东向断裂带、蚀变带、矿化带以及矿化中心的关系 ,并指出了其找矿意义 .根据大金发藓常与芒箕 [Di cranopterisdichotoma(Thunb .)Bernb .]、南烛 (LyoniaSp .)、蜈蚣草 (PterisVittataL .)等共生密切 ,结合其灰分分析资料计算成矿元素富集系数 ,分析了这一特征植物组合对找寻滥木厂式铊 (汞 )矿床的作用。This paper disucsses how to apply the geobiotanical method to the Lanmuchang thallium (mercury) ore deposits.First,geobioganical mapping was made according to the plant combination and distribution.The statistics of distribution density of Polytrichum commune Hedw was obtained from observation points within 120×60 m.Then,the extending direction of equal value line of density and the distribution district of different equal value lines of density were examined in relation to fault zone,alteration zone,ore-forming zone and mineralization centre,which was considered of prospecting significance.Finally,the important role of the characteristic plant combination in prospecting the Lanmuchang type thallium (mecury) ore deposits was expaunded in the light of the close coexistence of Polytrichum commune Hedw and Dichotoma (Thwd) Berh.,Liponia sp.,Pteris Vittate L.and the calculation of their concentration coefficients based on the data of ashes from the above plants.
