Abstract:
“Geologi Daerah Warkapi dan Sekitarnya Distrik Tanah Rubuh Kabupaten Manokwari
Selatan Provinsi Papua Barat” Geographically, the research area is located between 1○8'00”-
1○12'00” South Latitude and 134○5'00”- 134○9'00” East Longitude with geomorphological
conditions divided into two units and one deposit, namely Hills-Tersayat Topography Strong
Danudasional, Strong undulating topography- Denudational Hills, and Fluvial plains. There are
Denditric, Parallel and Trelis flow patterns, There are channel bars and point bars, there is a
"V"-shaped river for the young river stage and the letter "U" for the adult stage. The
stratigraphy of the research area can be grouped into several rock units and the oldest and
youngest sedimentary sequences. Andesite Units, Breccia Units, Sandstone Units, and Alluvial
Deposits that are not in harmony with the older units. The structure of the research area has
scouring joints with the main force direction N 60, and the structure that develops in the study
area is a right-down fault. The positive potential of the research area is that the product of
origin rock can be used as building material, while the negative potential of the research area is prone to landslides.
