The aim
of the study is find out the intrusion of crystalline
limestone and faultzone indentification in Pandalgudi mines,
Ramco Cement Pvt Ltd, Tamilnadu. The Crystalline limestone
formed in this region due to the geotectonic intrusion of
Calgic Granite in the Southern Granite Terrian (SGT) of
Madurai Block. The high quality crystalline limestones were
mined in this Pandalgudi region. The tectonically formed
faulted zone and open cast mine were mapped through the 2D
Electrical Resistivity Imaging (ERI) technique. 2D ERI
technique were covered both vertical and horizontal
pseudosection to display the subsurface intrusive, weathered
soil and Crystalline limestone in the study area. The 2D ERI
study has been carried out using the equipment resistivity
meter, Multicore cable, rods and Res2DINV software. These
apparent resistivity pseudosectioon were display the range
of resistivity in the three profiles obtained average
apparent resistivity (1-100 Ohm weather soil, 100-600
weathered limestone, 1400-14000 Ohm.m- Calcic Granulite
rock) indicate the subsurface geological condition of the
pandalgudi open cast mine.
