Geophysical Study: Estimation of Deposit Depth Using Gravimetric Data and Euler Method (Jalalabad Iron Mine, Kerman Province of IRAN)

Abstract

Mineral exploration is done by different methods. Geophysical and geochemical studies are two powerful tools in this field. In integrated studies, the results of each study are used to determine the location of the drilling boreholes. The purpose of this study is to use field geophysics to calculate the depth of mineral reserve. The study area is located 38 km from Zarand city called Jalalabad iron mine. In this study, gravimetric data were measured and mineral depth was calculated using the Euler method. 1314 readings have been performed in this area. The rocks of the region include volcanic and sedimentary. The source of the mineralization in the area is hydrothermal processes. After gravity measuring in the region, the data were corrected, then various methods such as anomalous map remaining in levels one and two, upward expansion, first and second-degree vertical derivatives, analytical method, and analytical signal were drawn, and finally, the depth of the deposit was estimated by Euler method. As a result, the depth of the mineral deposit was calculated to be between 20 and 30 meters on average.

Application of GOCE Satellite Gravimetric Data For Mineral Exploration

“…Using gravimetric data, Shirazy, Nazerian, Khayer, and Hezarkhani [12] estimated the depth of mineral deposits at the Jalalabad mine in the Kerman province of Iran. Non-uniform anomaly maps were produced that depicted various objects underneath the earth at various depths with varying densities.…”

The Use of Edge Enhancement Methods and Euler Deconvolution to Estimate an Ore Deposit Depth from Gravity Data

“…This study concerns the gossan of Benslimane. The Benslimane gossan is a sulfide deposit of Zn-Cu-Pb located at the south-eastern extension of the Kettara deposit [11]. This gossan constitutes with the Kettara in the North-East and Kerkoz in the South, one of the main lineaments of sulfide deposits of the central Jebilet massif (Figure 1(b)).…”
