Mineral Targeting Through Integration of Geological, Aero Geophysical and Remote Sensing Data-A Case Study

摘要

Application of the remote sensing technique helps in delineating various geological features such as lineaments, faults, fractures, shears and dykes that have great bearing in locating mineralised zones. Aero-magnetic data provide an insight into the subsurface geology and the data can be used effectively to compliment the surface geology. As a case study, a part of the Ramagiri-Penakacherla schist belt covering an area of 1296 km~2 in Andhra Pradesh (Fig. 1) was taken up. IRS-1D LISS III satellite images acquired from NRSA and aerogeophysical data acquired by the Twin Otter Aircraft of Geological Survey of India were used in integrated studies. The data were interpreted and integrated with the existing geological data using GIS platform and the interpreted studies were validated through limited field checks. A total of 11 target blocks were demarcated based on this interpretation for further detailed study.
