Mapping of Marble and Associated Structural Features using HLEM, ERT and IP Techniques, Pur-Banera Belt, Bhilwara, Rajasthan.

Horizontal Loop Electromagnetic (HLEM), Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) surveys were conducted over the exposed marble and associated rock units region, Bhilwara, Rajasthan to understand the response of the geophysical anomalies. A negative Slingram (+0 % to ~120%) response in both IP and OP components of 110 Hz frequency and high resistivity (2000 to >8000 ohm-m) observed over the known Marble formation.
