Abstract

This research was conducted in the Cipajang Village area and its surroundings, Banjarharjo District, Brebes Regency, Central Java Province. This mapping was carried out using a surface mapping method by looking at rock outcrop data, rock distribution, geomorphology and physical characteristics of rocks. This concept is called the lithostratigraphic concept. In this type 1 thesis activity, the researcher obtained 3 types of rock from old to young, namely: the Kumbang Andesite Breccia Unit which is not in harmony with the Pamali Carbonate Claystone Unit and which is in line with the Halang Carbonate Sandstone Unit. The geomorphology formed in the research area is: Denudasional Mountains & Hills Geomorphology Unit (D3), Denudasional Slope Hills Unit (D2), Alluvial Plain Unit (F3) Alluvial deposits (F1).
