Characterization of Rock Composing Minerals Using the X-Ray Diffraction Method at the Samaenre-Mallawa Hot Spring, Maros Regency

One of the areas in Maros Regency that has geothermal potential is located Samaenre, Mallawa District, where hot springs are a few kilometers from residential areas. This water source around river. Hot produced as result discharge groundwater earth's crust after being heated geothermal. Research been carried out aims to determine mineral content and crystal structure by using X-Ray Diffraction method. Samples were obtained depth 1 meter at points A, B, C, D E. XRD test results showed was silicon oxide, kaolinite, magnetite, calcium peroxide, Dobassite-2M1a, alpha-SiO2, Calcium Peroxide, Maghemite-Q , Aragonite, Paragonite 2M1, Gehlenite, UTD-1, Silicon Oxide, Pyrophyllite 1A dehydroxylated, 3T, UTD-1. Most five samples oxide minerals. The structures seen tetragonal CaO2, Fe2O3, (Ca2 (Al0.92 Mg0.08) ((AlO.92), orthorhombic Ca (CO3), Si112 O224, Si O2, hexagonal SiO2, Na Al2 (Al Si3 O10) ( OH)2, monoclinic Al4.5 (Al8.5Si3.2) O10(OH)8, NaAl2 ((AlSi3) O10 (OH)2, triclinic Al4(OH)8(Si4O10), Al4Si2 O22 cubic Fe3O4.
