Geology and geochemistry evolution of igneous rock in Carita, Indonesia

Volcanism has occuring in Indonesia from the birth of its land and up until now. Throughout the process, it forms an igneous rock that scattered inside the Banten Province. Throughout the formation process of the igneous rock, it evolves from the more mafic magma down to the more basic in characteristic and changing its chemical composition throughout the partial melting and fractional crystallization process. The purpose of this paper are 1) to produce a geological map of the study area in scale 1 : 30 000, 2) to identify the mineral and chemical content of the rock in the study area, 3) to identify the evolution of igneous rock inside the study area. In this research, the methods that have been used were geological mapping, petrographic analysis, X-Ray Fluorescence major element detecting and SiO2 vs K20, Ti02-10MnO-P205 and AFM triangular geochemistry diagram plotting.
