Abstract

The research area is administratively located in Banjarharjo Village, Banjarharjo District, Brebes Regency, Central Java Province. Geographically, the research area is located at coordinates 108o 49 '15.4 "- 108o 52' 30.8" East Longitude and 06o 59 "21.8" - 07o 02 '04.8 "LS. The research area is included in The North Central Java Basin (The North Serayu Through/Basin) which is a Back Arc Basin. Based on the stratigraphic and sedimentological composition, the research area is classified into five geological units, (old to young), namely: (1) Sandstone and Claystone Interchange Unit, (2) Carbonate Claystone Unit, (3) Sand Limestone Unit, (4) Volcanic Breccia Unit and (5) Andesite Intrusion Unit. According to Pulonggono and Martodjojo (1994) Java Island, there are three straight lines of dominant structure, including: (1) East Laur - Southwest (Meratus Pattern), (2) North - South (Sundanese Pattern) and (3) West - East (Pattern Java). Based on the strike dip and stockiness data at the research location, the results of the force with the direction of the main stress are relatively Northeast-Southwestern, with the combination of Harding modeling, (1977) and Moody and Hill, (1956). The structural arrangements in the research area that are formed are (1) Cibuluh thrust fault, (2) Maibah sinistral strike-slip fault, (3) Cikuya sinistral strike-slip fault, and (4) Cikuya dextral strikeslip fault.

基于中爪哇省布赖布斯区班加哈若地区地表数据的地质构造分析

研究区域在行政上位于中爪哇省 Brebes 县 Banjarharjo 区 Banjarharjo 村。在地理位置上，研究区位于东经 108o 49 '15.4"- 108o 52' 30.8 "和南纬 06o 59 "21.8"- 07o 02 '04.8"。研究区域位于爪哇岛中北部盆地（北塞拉尤盆地），该盆地属于后弧盆地。根据地层和沉积构成，研究区域被划分为五个地质单元（从老到新），即：(1) 砂岩和粘土岩交汇单元；(2) 碳酸盐粘土岩单元；(3) 砂质石灰岩单元；(4) 火山碎屑岩单元；(5) 安山岩侵入单元。根据 Pulonggono 和 Martodjojo（1994 年）的研究，爪哇岛的主要构造有三条直线，包括：(1) 东劳尔-西南（梅拉图斯模式）、(2) 北-南（巽他模式）和 (3) 西-东（爪哇模式）。根据研究地点的走向倾角和储量数据，结合哈丁建模（1977 年）和穆迪与希尔建模（1956 年），主应力方向的受力结果相对为东北-西南。研究区内形成的构造布置有：（1）锡布鲁赫推断断层；（2）麦巴正弦走向滑动断层；（3）锡库亚正弦走向滑动断层；（4）锡库亚右旋走向滑动断层。
