Abstract

Abstract. TalawiHilir Village, Talawi HilirSubdistrict, Sawahlunto City, West
Sumatra Province is one of the areas that have interesting geological conditions to
study. The objective of this research are interpret of some unicharacteristic include:
geomorphologic processes, depositional environment and potentialgeotourism. The
methods of study consist of geological data field collection and laboratory include: rock
sample, collect data of strike/dip, contact between lithologies, structure of geology,
geomorphological photo and map. The result of the analysis of geomorphological
aspects of the study area was classified into four units: Alluvial Plain Fluvial
Geomorphology Unit, High Hills Undulating Structural Geomorphology Unit, Steep
Hills Structural Geomorphology Unit, Very Rough Mountains Denudation
Geomorphology Unit. Petrological analysis classified into four units lithologies:
Claystone Unit, Limestone Units, Sandstone Units and Breccia Unit. Claystone Unit as
interprets in shallow marine depositional environments on the lower fan, which is
characterized by the flow turbidite. Limestone Unit as interpret as depositional
environments in shallow sea, the Sandstone Unit as interpret as lacustrine depositional
environment and Breccia Unit as interpret as alluvial fan depositional environment.
Geotourism potential particularly in geological variation, research area were unique
characterization on landscape, landform, rock outcrop, rock unit, rock type, and
minerals.
