摘要

根据印尼能源和矿产资源部（MEMR）2017 年发布的《地热潜力手册》，印尼东爪哇省帕奇坦地区具有地热能源潜力。两个温泉表现地，即 Karangrejo 和 Tinatar，分别位于帕契丹行政区的 Arjosari 和 Punung 地区，合计资源量为 25 兆瓦特。我们获取了地面重力数据并对重力异常进行了评估，以探索潜在的地质结构，从而了解这些地热资源背后的地热系统。研究结果表明，Karangrejo-Tinatar 地区的重力异常范围在 163 至 176 mGal 之间。对完整布格尔异常（CBA）图、第一水平导数（FHD）图和实地观测的进一步分析表明，该地区存在三个西北-东南走向的断层。其中两个断层，即 Karangrejo 断层和 Tinatar 断层，可能是 Karangrejo 和 Tinatar 温泉的流动路径。

Preliminary Study of Subsurface Geological Setting Based on the Gravity Anomalies in Karangrejo-Tinatar Geothermal Area, Pacitan Regency, Indonesia

As per the Geothermal Potential Book published by the Ministry of Energy and Mineral Resources (MEMR) in 2017, Pacitan Regency in East Java Province, Indonesia, has the potential for geothermal energy. Two hot spring manifestations, namely, Karangrejo and Tinatar, located in the Arjosari and Punung districts of Pacitan Regency, respectively, have a combined resource of 25 MWe. We acquired ground-gravity data and evaluated gravity anomalies to explore the underlying geological structure in order to understand the geothermal system behind these manifestations. The results of the study show that the gravitational anomaly in the Karangrejo-Tinatar region ranges from 163 to 176 mGal. Additional analysis of the complete Bouguer anomaly (CBA) map, first horizontal derivative (FHD) map, and field observations points to the existence of three NW-SE trending faults. Two of the faults, which are the Karangrejo fault and the Tinatar fault, may be the flow paths for the manifestation of Karangrejo and Tinatar hot springs.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
