Heavy-concentrate has been found to be the most suitable sampling medium in geochemical exploration for gold in Atkur area of Gadwal schist belt, Mahabubnagar district, Andhra Pradesh. Au-contents in panned heavy concentrates of soil samples from B-horizon and termite mounds helped in improving gold anomaly contrast. SEM and heavy-concentrate analyses of termite samples reaffirm their utility in exploration for gold. Hence, the study of heavy fraction of soil and termite mound can be used as an important tool to reveal the subtle anomaly present in the conventional samples.

Abstract


Heavy-concentrate has been found to be the most suitable sampling medium in geochemical exploration for gold in Atkur area of Gadwal schist belt, Mahabubnagar district, Andhra Pradesh. Au-contents in panned heavy concentrates of soil samples from B-horizon and termite mounds helped in improving gold anomaly contrast. SEM and heavy-concentrate analyses of termite samples reaffirm their utility in exploration for gold. Hence, the study of heavy fraction of soil and termite mound can be used as an important tool to reveal the subtle anomaly present in the conventional samples.
