Abstract

Fold pattern of the Tertiary sedimentary rock in Majalengka represents east-west orientation as a partof Jawa fault thrust belts. In the Bantarujeg area, the orientation of those folds are slightly different tothe major east-west orientations due to different shear strength that controls this region as a product ofheterogenity block movement in orientation and speed. It was causing rock mass break laterally andproduce tear faults and/or strike-slip faults. Along the faults, strain direction rotated and bend thestratification of sedimentary rocks along the fault. However, pattern of stratification is depend on thetime development of fault system since the stratifications are not influenced by faults.Step of works of this research was starting by interpret structure and lineament from DEM data, thuscombined by field work data that consists of strike and dip of stratification, lithology and stratigraphysuccession.Keywords : rotation, copel, strain system, anjakan fold, strike pattern, stereographic projection Pola struktur lipatan pada batuan sedimen Tersier di daerah Majalengka, merupakan bagian dari polastruktur lipatan anjakan Jawa yang secara regional berarah barat-timur. Di daerah Bantarujeg, sebagiandari pola struktur ini membusur karena adanya pengaruh tegasan kopel. Tegasan kopel terjadi ketikamasa batuan yang bergerak memiliki kecepatan yang berbeda di setiap segmennya. Peristiwa inimenyebabkan masa batuan robek secara lateral yang akhirnya membentuk tear fault atau sesarmendatar lokal. Selama berlangsungnya peristiwa ini, arah tegasan berotasi dan menyebabkan lapisanbatuan melengkung secara lateral di sekitar zona sesarnya. Tidak semua sesar mendatar merubah polajurus lapisan batuan, hal ini tergantung kepada waktu pembentukannya, yaitu apakah lipatan seret initerbentuk bersamaan dengan pembentukan struktur lipatan anjakan ataukah terjadi sesudahnya.Metoda penelitian dilakukan dengan menganalisis kelurusan struktur melalui DEM, dilanjutkan denganmengukur kedudukan strike dan dip lapisan di lapangan. Selanjutnya dengan mengkompilasi aspekmorfologi dan stratigrafinya, akan diketahui sejauh mana kontrol tear fault merubah pola jurus di daerahini. Pengolahan data struktur dilakukan dengan analisis dem, rekontruksi pola jurus dan proyeksistereografi.Kata kunci : rotasi, kopel, sistem tegasan, lipatan anjakan, pola jurus, proyeksi sterografi.

Abstract

There are four major fault lines pattern that developed in Tertiary sedimentary rocks in the Western Part of Java Island, that are the east-west, north-south, northwest-southeast and northeast-southwest. Fault structures with the east-west direction generally existed as a reverse fault and as the main fault patterns that control the distribution of rocks on the surface. Regionally, together with structural folds, these fault structures has formed the thrust fold belt structure. The other faults direction, generally known as the secondary faults that formed simultaneously with the thrust fold belt structure. These faulst are generally as strike slip fault or oblique faults that are transtensional or transpressional. This fault pattern is formed when a horizontal force strength differences in each segment. From the Compilation of the fold structures data, faults and the stratigraphy, it can be concluded that the geological structure developed in Tertiary sedimentary rocks in the western part of Java Island, began formed at late Tertiary, under the main compressional system, which is north-south trending.

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.

Abstract

Java Island is a region of frequent earthquakes with varying strength. Most of destructive earthquakes measuring over 5.6 on the Richter Scale, as a shallow earthquake with a depth of less than 30 KM. On land, the earthquake can damage a variety of infrastructure and endanger lives. At ocean, earthquakes tend to be a potential tsunami. The tsunami that ever happens is in the south of Pangandaran beach on July 27, 2006. To reduce the impact of the earthquake disaster, the identification and mitigation is required. In the identification of the earthquake in the mainland, the earthquake potential of fault-lines are shown on a large faults, there are: Earthquake's Row of Zone Bayah, Earthquake Row of Baribis Zone, Earthquake Row of Cimandiri Zone, Earthquake Row of Lembang Zone, Earthquake Row of Citanduy Zone. On the identification of the earthquake in the ocean, is required analysis to see the condition of the epicenter in the southern Teluk Pelabuhan Ratu. Mitigation of earthquake disaster can be done, among others through the various activities that need to be socialized, assisted by experts from various disciplines.

Abstract

The geology of the Aceh Baratdaya has been controlled by convergence of the Eurasian and Indian lithospheric plates since the Mesozoic era. Various types of rock—including the metamorphic, meta-sedimentary, volcanic, and plutonic rocks—and the associated economic mineral deposits have been formed by diverse geologic proceses (i.e., sedimentation, lithification, metamorphosis, crystallization, and structural processes) associated with convergent plate interactions.The magnetic iron ores in the study area are interpreted as the crystallization product of hydrothermal solutions. Genetically, the iron ore in the study area is of lateritic type. Most of the ores in the study area are spread in northwest-southeast direction, in harmony with the general trend of faults and folds.
