通过探讨福建省平和县钟腾、泮池、鸡笼山、大芹山4个主要矿区内地球化学元素在岩-土-植被中的迁移规律,以期为该区植物地球化学找矿提供依据。研究表明,土壤中主要金属元素及稀土元素REE的分配规律在垂向上与岩石具有一致性;植物对元素种类的吸收具有选择性,Zn在该区植物中显示强积聚的特征,Co、Ni、Cu属一般积聚型元素,Bi、Mo、As是弱积聚型元素。毛蕨和夹竹桃对稀土元素REE的富集十分明显,超过平均含量达千倍以上。初步判断毛蕨、夹竹桃对在研究区内寻找铜钼矿具有一定的指示意义。
Through the study of the geochemical migration of geochemical elements in rock-soil-vegetation in four major mining areas, Zhongteng, Panchi, Jilongshan, and Dacqinshan in Pinghe County, Fujian Province, the study aims to provide evidence for geochemical prospecting in this area. The results showed that the distribution rule of REE and REE in the soil was consistent with the rock in the vertical direction. The plant was selective for the absorption of elemental species. Zn showed strong accumulation in the plants of this area. The distribution of Co, Ni, Cu is a general accumulation of elements, Bi, Mo, As is a weak accumulation of elements. Fern and oleander rich REE enrichment of REEs is very obvious, exceeding the average content of more than a thousand times. Preliminary judgment of the hair fern, oleander in the study area to find copper and molybdenum has some significance.
