Characterizing of tectonic and non-tectonic morphology based on morphometric and morphotectonic analysis on cigugur watershed, Pangandaran for genetic-landform recognizing zone

Misconception in the determining of tectonic geomorphological units are not always related to the geological structures in the field, especially in the pre-quartenary material whether the results of tectonic processes such as landscapes can withstand present or can still be seen. The determination of the tectonic landscape using a morphotectonic approach can be used in determining the tectonic or non-tectonic landscape still present. This research uses quantitative parameters such as the use of morphotectonic parameters such as Drainage Density Index (Dd), Bifurcation Ratio (Rb) and Sinusity of Front Mountain (Smf) and observation of lineament pattern and qualitative parameters such as lithology aspect (existing material type), Tectonics (geological structure) and Morphology (Morphography). Aspects of lithology in the study area consist of breccias unit, carbonaceous sandstone units and limestone units. Lineament with dominant NW-SW direction. The drainage pattern of the developing river is dominated by parallel with other drainage patterns such as Sub-dendritic and multibasinal. The result of calculation of morphotectonic parameter with Rb value ranged from 3,5 to 4,567. The value of Dd obtained ranges an average of 1.08 to 4,4 km / km2. Smf value obtained 1,2 to 1,6. It can be categorized that the values of the study area on the lower to medium tectonic landscape zone with dominant denudational landscape based on the various complex landscape forming
