Abstract:
Surface water is coming from rivers, rain, lakes, seas, and others seeps into
groundwater, flows and comes into contact with the magma or hot, frozen bodies, boils and
then forms water and steam (hydrothermal), due to specific gravity, temperature, and its
pressure, this steam and hot water flows back to the surface through the fracture fields in the
earth's crust. The research purposes are to identify the types of sediments and minerals found in
the Hot Water Regions precisely located in Bulue Village, Marioriawa District, Soppeng
Regency, South Sulawesi Province. This research uses the X-Ray Diffraction (XRD),
resistivity meter, Electrode (potential electrode and current electrode) and Res2Dinv software
for calculating the apparent resistivity based on the Wenner-Schlumberger configuration
geometry factor and minerals dominance. Geoelectric results show silt and clay sediments are
found to be dominant in Soppeng Regency hot springs. Silica is the central part that forms the
rock, both rocks and rocks sediments. Furthermore, the result of X-Ray Diffraction (XRD) of
mineral for three soil samples is dominated by Sodium-potassium to Aluminosilicate (41%),
Sanidine (35%), Sanidine (equal to 47%) (Sanidine is mineral found mostly in volcanic rocks).
