GEOARKEOLOGI CEKUNGAN SOA, FLORES, NUSA TENGGARA TIMUR

Soa Basin, which belongs to Ngada Regency and Nagekeo Regency, is located on Flores Island, with many cultural stays, among others, from the Paleolithic period, which has not been too concerned by environmental researchers, especially geoarkeology. This is the issue that covers general geological conditions. The purpose of this research is to mapping the surface geology in general as an effort to present geological information related to archeological site. The aim is to know the geomorphological, stratigraphic aspects of the archaeological sites. The research method is done through literature review, survey, field data analysis and interpretation. Environmental observations provide information on the landscape of the study area consisting of terrestrial morphology units, and weak wavy morphology units. The river is centripetal flow pattern, with the old river, mature-old river, periodic/permanent river, and episodik /intermittent river. Constituent rocks are volcanic breccias, tuffs, conglomerates, and alluvial deposits. The geological structure is a fracture of the normal fault type. Exploration in the Soa Basin has listed 12 paleolithic sites. From the classification of petrology, litik tools made of jasper, chert, andesite, and basalt rocks. Rock as a raw material litik, found in Soa Basin and surrounding areas, both in the form of outcrops and boulder.
