Abstract

The mud flow which identified in Ciuyah area is located in Ciniru village, District Ciniru, Kuningan regency, West Java. Study of morphometry through the deployment of slope classes have described the class as a concentric distribution with location of Ciuyah mud flow in the middle. Annular’s drainage pattern at the regional scale is reflected of the circular in the Ciniru area, at around of site Ciniru extrusion Ciuyah mud mound. Circular patterns of distribution shown by the slope zone, and annular flow patterns in the river a more regional scale is suggest updoming beneath the surface. Interpreted that the migration channel and the possible fluid circulation is controlled by faults that developed in the study area. Structural geology are factors that contribute to the release or migration of fluid to the surface, and provide an outlet for material and fluid under conditions of excessive stress, clayey material which forming of bedrock formations is elusiation experience process, and eventually formed mountains of mud intrusion on the surface

Abstract

Central Sumatera basin controlled by an amount of regional stike-slip fault (wrench fault) moving on transtensinal system. Overall srike-slip pattern forming as negative flower structure, yielding horst and garben. This tecotonic process happened in Early Miocene.Graben forming begin the sedimentation process which indicate the coarse clastica deposit existence that goes on fluvial environment. This deposit equivalent with Sihapas formation that have an age of Eosen. The Sedimentary basin had a subsidence continuously till Middle of Miocene, that indicated by developt marine sedimentary rock.In Plio-Pleistocene, the uplifting processes is happen again that cause forming of fold and fault structure. Tectonic compression cause the research area more shallow and then become a continent. This is indicated by developted conglomerate, sandy conglomerate, tuffaceous sandstone which forming in continent.
