Characteristics and prospecting significance of the phytogechemistry in Duobaoshan cupper metallogenic field, Daxing'anling area, NE China

Effective prospection can be take using phytogeochemistry in forest cover area. The study of phytogeochemistry in Duobaoshan copper metallogenic field and adjacent area has been carried out. The samples are common plants in the plant samples measurement and taken from roots, stems and leaves, respectively. The rock and soil samples were collected from the same place with plant samples. The analytical method of the plant samples is ICP-MS. Obvious phytogeochemical anomalies can be recognized by the metallogenic elements contrast method and total enriched coefficient (TEC). The phytogeochemical anomalies have genetic relationship with the mineralization proved by the shielding coefficient (SC) and the correlation analysis of mineralized rock, soil and plants. There are some interfered factors in phytogeochemical exploration. The phytogeochemical samples can be determined by the distribution of elements in the plant organs. The contrast coefficient (CC), combination contrast coefficient (CCC) and shielding coefficient (SC) have been used to select effective indicator plants. It can be concluded that platyphylla and lespedeza are the effective indicator plants in Duobaoshan copper metallogenic field. Phytogeochemical exploration in Daxing'anling forest cover area is practicable.
