Potensi Sebaran Mineral di Bawah Permukaan dengan Metode Geolistrik di Pantai Kuri Caddi Maros

Abstract

Minerals play a very important role in everyday life, for example, non-metallic minerals are used as industrial raw materials, ceramic materials, cosmetic materials, building materials, etc., while metallic minerals are used in industry. The purpose of this research is to reveal the spreading of minerals under the surface of Kuri Caddi Beach in Maros by applying Geoelectrical Resistivity Method. This research was passing the process of data geoelectrical acquisition by using wenner configurations with two tracks. The length of each track is 120 meters with 5 meters of electrode space. In this research two layers were obtained in the first pass, the first layer with a specific resistance value of 0,302-3,03 Ωm was found at a depth of 0-12,4 meters, presumably the distribution of sand with minerals calcium oxide, silicon dioxide and Hematite. The second layer with a resistivitas of 5,40-17,1 Ωm is located at a depth of 3,75-19,8 meters. The distribution of sand deposits is believed to contain the minerals calcium oxide, silicon dioxide and hematite. Two layers are also obtained in the second pass, the first layer with a specific resistance value of 0.166-1.60 Ωm was found at a depth of 0-15.9 meters, presumably the distribution of sand with the minerals calcium oxide, silicon dioxide and hematite . The second layer with a resistance value of 2.82-8.78 Ωm is located at a depth of 0-19.8 meters, it is assumed that the distribution of sand deposits with the minerals calcium oxide, silicon dioxide and hematite. From the results of the study it can be seen that the distribution of minerals with resistance values between 0.166-17.1 Ωm is at a depth of 0-19.8 meters.
