REMORE SENSING
[attachment=41685]
INTRODUCTION
India is rich in mineral deposits including asbestos, mica, barite and talc. Integration of available background information (viz. geology, tectonics, mineralogy and geomorphology) in GIS environment leads to development of Mineral Exploration Geographic Information System. This study examines the use of remote sensing in geological studies in south east Rajasthan. Landsat Enhanced Thematic Mapper plus (ETM+) and TM were used to
(i) classify the various geological units found in study area
(ii) Discriminate the Lithology and structure of this area
(iii) Delineate the associated zones for mineral identification.
The search for metals and materials needed to sustain our culture has been carried out since primitive man has searched for flint to craft hand tools. Today, the materials needed to drive our economic and technological growth are just as crucial. Most of the easily accessible metal ores were discovered decades ago; and thus the search has turned to more subtle deposits and more remote locations.
Since the inception of rudimentary aerial photography at the turn of the twentieth century, remote sensing has been used as a tool in the search for economic mineral deposits. As the level of technology has improved, the value of remotely sensed data has increased. The page will highlight the history and implementations of remote sensing on mineral exploration today.
