Soil geochemical anomly characteristics and the geological significance of soil geochemical survey at Kavanga area in Kigoma,Tanzania
Kavanga area of Kigoma in Tanzania is located in tropic geochemical landscape area with poor geological survey.In certain extent soil geochemical survey is carried out at scale 1..50 000then optimum anomlies are screen out to be working areas for soil geochemical survey at scale 1..10 000and integrated Cu Pb Zn anolies with good morphology and sequential elements overprinting are lineated.The integrated anomlies are checked with field survey and trenching.Malachite is discovered in muddy shale with stable attitude and the anolies are controlled by NNE faults.The metal mineralization is controlled by both of the stratum and faults thus the area is payable for further exploration.
