| Abstract: | Using a set of copper assay values (from soil samples collected near Surda, Singhbhum Dt., Bihar) and applying numerical methods,
such as relaxation, trend surface, composite analysis, and linear moving average, residuals have been determined. Zones of
positive and negative anomalies are delineated and an attempt has been made to correlate with the structural phenomena and
drainage pattern of the region. |
