<p>The Geological Resources Bulletin (Buletin Sumber Daya Geologi) is a LIPI-accredited scientific journal covering the fields of minerals, fossil energy, and geothermal energy. It is published three times a year, in May, August, and November.</p> <p>In 2010, the Geological Resources Bulletin received Accreditation B as a scientific journal, which was renewed in 2012. The most recent accreditation, granted in 2015, was valid for three years, with the ISSN (print) number: 1907-5367. In 2017, the bulletin was assigned the eISSN number: 2580-1023 for its online edition.</p> <p>In 2018, the Geological Resources Bulletin was awarded a Rank 2 accreditation by the Ministry of Research, Technology, and Higher Education as a Scientific Journal. This ranking was reaffirmed in 2020, with the accreditation valid for the next five years.</p> <div class="O1"> </div> <div class="O1"><strong><em>DOI Prefix: 10.47599</em></strong></div>Pusat Sumber Daya Mineral Batubara dan Panas Bumien-USBuletin Sumber Daya Geologi1907-5367<p>Penulis yang naskahnya diterbitkan menyetujui ketentuan sebagai berikut:</p> <p>Hak publikasi atas semua materi naskah jurnal yang diterbitkan/dipublikasikan dalam situs Buletin Sumber Daya Geologi ini dipegang oleh dewan redaksi dengan sepengetahuan penulis (hak moral tetap milik penulis naskah).</p> <p>Ketentuan legal formal untuk akses artikel digital jurnal elektronik ini tunduk pada ketentuan lisensi <strong><em>Creative Commons Attribution-</em></strong><strong><em>ShareAlike</em></strong> (<a href="https://creativecommons.org/licenses/by-sa/4.0/" target="_blank" rel="noopener">CC BY-SA</a>), yang berarti Buletin Sumber Daya Geologi berhak menyimpan, mengalih media/format-kan, mengelola dalam bentuk pangkalan data (database), merawat, dan mempublikasikan artikel tanpa meminta izin dari Penulis selama tetap mencantumkan nama Penulis sebagai pemilik hak cipta.</p> <p>Naskah yang diterbitkan/dipublikasikan secara cetak dan elektronik bersifat <a href="http://www.budapestopenaccessinitiative.org/" target="_blank" rel="noopener">open access</a> untuk tujuan pendidikan, penelitian, penyelidikan, dan perpustakaan.

<p><em>The research is located in Cihaur, Sukabumi, West Java, occupied by the Jampang Formation, located in the Sunda-Banda Arc. The magmatic activity and complex tectonic setting in the arc have the potential to cause mineralization, resulting in several types of ore deposits such as porphyry, epithermal and skarn. The objectives of this research are to identify alteration, mineralization, and ore deposit types in the research area. The research methodology includes exploration drilling, alteration mapping, and laboratory analysis using XRD, petrography, and mineragraphy methods. Alteration of the research area consists of argillic alteration (illite, kaolin, and smectite), propylitic alteration (chlorite, epidote, and calcite), marbellized (95% calcite), and skarnization (clinopyroxene, wollastonite, chlorite-skarn, and epidote-skarn). In the skarn there are indications of a prograde stage characterized by pyroxene and wollastonite minerals, and a retrograde stage characterized by epidote, calcite, and chlorite minerals. Mineralization of the research area consists of galena, sphalerite, pyrrhotite, pyrite, and chalcopyrite. The presence of pyroxene and wollastonite minerals, as well as galena and sphalerite indicate that the skarn formed in the intermediate to distal zone.</em></p>Nadya FinlandiniSabtanto Joko SupraptoAsep M I ShiddiqLia NovaliaMuhammad Syafrudin Anshar
