Abstract
Summary
Indonesia is a country of Island arcs setting, tectonically. This setting has induced many of volcanoes Indonesia followed by the presence of mineral deposits. As the consequences of never-ending demand for ore minerals, exploration of mineral deposits are always needed. The study area is located in Kulonprogo, Yogyakarta. The study area is marked by secondary type mineral deposit presence of Placer type. Several band combinations analysis of Landsat 8 OLI/ TIRS 432, 567, and rationing of band 5/6 and 4/2 are done as methods in order to reveal the geological, and geomorphological conditions of the study area and the dissemination of iron-bearing mineral in the source and in the secondary deposit. The result of the analysis is the dissemination of the iron-bearing mineral are present covered wide area within and around the Glagah beach, the iron mineral source are located several kilometers to the north, the transportation of iron-bearing mineral is done through fluvial mechanisms of Serang and the other River to the beaches in the south. Some factors are also expected to affect the deposition processes, such as mineral density, waves, and river’s current speed. From this study, it’s believed that remote sensing is useful “tool” in mineral exploration.
