- ABSTRAK Secara geologi, Indonesia di kenal kaya akan berbagai jenis mineral, salah satunya adalah emas. Akan tetapi, kandungan sumberdaya cadangan mineralnya kian menipis, sedangkan permintaan industri dan minat investasi dalam skala lokal maupun global terus meningkat seiring dengan pertumbuhan penduduk dan perkembangan industri. Oleh karena itu, perlu dilakukan eksplorasi sumberdaya mineral dengan menggunakan metode geofisika terintegrasi yang didukung oleh data geologi untuk mempermudah pengidentifikasian struktur dan zona alterasi sebagai pengontrol zona mineralisasi emas, agar dapat memenuhi kebutuhan yang terus meningkat. Sehingga diharapkan, penelitian dari metode terintegrasi ini dapat menjadi suatu pilihan dalam kegiatan eksplorasi sumberdaya mineral, khususnya mineral emas. Dari hasil integrasi antara respon kemagnetan metode Magnetik dan respon kelistrikan (resistivitas dan chargeabilitas) metode Time Domain Induced Polarization, maka zona mineralisasi emas berada pada lintasan 1 dan lintasan 2 diarah Barat Daya – Timur Laut Ciparay, lintasan 5, lintasan 6, lintasan 7, dan lintasan 8 diarah Barat Daya Ciparay yang ditunjukkan oleh nilai high magnetic anomaly, high resistivity dan high chargeability, serta berkembangnya zona alterasi argilik, yaitu illite dan smectite. ABSTRACT Geologically, Indonesia is known to be rich in various types of minerals, one of which is gold. However, the content of mineral reserves is running low, while the demand for industry and investment interest on a local and global scale continue to increase, along with population growth and industrial development. Therefore, it is necessary to explore mineral resources using integrated geophysical methods supported by geological data to facilitate the identification of structures and alteration zones as controllers of gold mineralization zones, to meet the ever-increasing needs. So hopefully, research from this integrated method can be an option in the exploration of mineral resources, especially gold minerals. From the results of the integration between the magnetic response of the Magnetic method and the electrical response (resistivity and chargeability) of the Time Domain Induced Polarization method, the gold mineralization zone is at lane 1 and lane 2 in the direction of Southwest - Northeast Ciparay, lane 5, lane 6, lane 7, and lane 8 in the direction of Southwest Ciparay which is indicated by the value of high magnetic anomaly, high resistivity, and high chargeability, as well as the development of argillic alteration zones, namely illite and smectite.
