Morphostructure analysis of Sapaya ancient volcanic area based lineament data

摘要

Abstract. Morphostructure of Sapaya ancient volcanic have been analysis by using lineament models. In this models, two methods of retrieval data have been used. First, the field survey of the area, second, the satellite images analysis. The morphostructure of Sapaya ancient volcanic contribute to the crater, caldera, and shown an eroded cone morphology. The directions of eruption from Sapaya ancient volcanic have identified in region of Jeneponto and Takalar, which is had east ??? west and northeast ??? southwest structure. These eruptions also give contribution to the character of river in Jenelataudwatershed, by the presence of tuffs, pillow lava, basalt, andesite, diorite, granodiorite, granite, and gabbro, respectively.
