Abstract

Process of deFormation has an effect on both dynamic and regional metamorphic rocks. Metamorphic rock of Manunggal Formation can be found as large outcrops in Karangsambung, Central Java. In this research, we did geological mapping in the Manunggal Formation outcrop area and took rock samples. The rock samples are then analysis macroscopically to determine their metamorphic facies. From our study, we are able to identify the various degrees of metamorphism within the study area. This variation are concluded from the detailed macroscopic of mineral composition and rock texture of the rock samples from Manunggal Formation. The metamorphism process in rocks produced foliation textures on metamorphic rocks that are either foliated like phyllite and schist, or non-foliated such as green rock, serpentinite, and hornfels. All of this variation are plotted into the geological map and showing specific trend that might be related to past tectonic activity in the study area.
