The resistivity method concerns with resistivity (ohm.m) of rocks which indicates the electrical properties in terms of ability to resist the flow of electrical current. The presence of manganese in rocks generally lowers the resistivity. The Induced Polarization (IP) method deals with chargeability (in msec) which indicates the strength of polarization effects experienced by ions in the vicinity of metallic grains in rock. The presence of manganese in rocks increases the chargeability of the rock when measured using IP method. The low resistivity zones (< 5 ohm.m) are situated in the western part, central part, and eastern part of the investigated area. These zones may strongly correlate to the presence of manganese ore. However, these low resistivity zones may have been influenced by the presence of clay or weathered soil. In this case, the high chargeability zones will help in confirming the prospective zones caused by manganese ore. The thicknesses of the manganese ore layer vary from about 5 to 20 m based on the cross-sections. Based on the results, we estimated the geometry of the associated manganese prospective zones for resistivity (10 msec).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]2-D resistivities,Electrical current,Induced polarization,Low resistivity,Metallic grains,Polarization effect,Resistivity methods,Weathered soils[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1742-6596/739/1/012138[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
