| 摘 要： | 根据前人在植物化探方面的研究成果，结合本区有色、贵金属矿化实际，选择了白桦树树干下部树皮为植物化探样品，进行了Au、Ag、Cu、Pb、Zn元素的测试.结果表明：①该区植物化探工作比土壤化探更具优越性；②白桦树树皮具有易采、易灰化的特点；③植物化探结果，可良好地反映出已知的Au、Pb、Zn矿化-蚀变带.用植物化探方法找矿，在该区具有良好的适用性和可靠性，有一定的推广价值.

| Abstract: | Based on the previous study on biogeochemical exploration,combining the geology of non ferrous and precious metallic mineralization of the area,the bark from lower trunk of betula is selected as the sampling media of biogeochemical survey. The contents of Au,Ag,Cu,Pb and Zn elements are tested The results show that:1)biogeochemical survey is more effective than soil geochemical survey;2)the bark of betula is characterized by easily picking and ashing; and3)the biogeochemical result coincides well to the known Au Pb Zn mineralization alteration belts Biogeochemical survey in this area is suitable and reliable It is worth to be spread |
