The southern mountains of Java are a path of copper-gold mineralization that has proven to have high economic value. Pacitan is part of the geological system and mineralization of the southern mountains, which are part of the Sunda Arc magmatism. The research area is located in the copper mining location in Kluwih village, Tulakan, Pacitan, East Ja...
The southern mountains of western Java have been known to have large gold deposit potential. The Mekarbakti area, located in Garut regency, is known to have gold-bearing quartz veins, but the distribution and characteristics of these veins are not well recorded. The purpose of this study is to determine the geological conditions of the deposits and...
The study area, i.e Humpa Leu East is a porphyry prospect located in Hu'u district, Sumbawa Island, Indonesia. This study is aimed to understand the characteristics of veins, the distribution of veins and mineralogy, microthermometric conditions of ore fluids, distribution of elements, and their implications for exploration and deposit model. The H...
Indonesia is a country that has several world-class copper-gold deposits, particularly in eastern Sunda arc. The Hu’u complex has several prospects in the surface as lithocap of extensive epithermal style alteration, but some were detected associated with porphyry beneath the surface. The study focuses on hydrothermal breccia cement as a factor inf...
ABSTRAK Pegunungan Kulon Progo merupakan produk magmatisme Busur Sunda-Banda tersusun atas formasi andesit tua. Daerah Sumbersari merupakan bagian dari gunung api Gajah, batuan gunung api tertua Kulon Progo. Indikasi mineralisasi tipe porfiri ditemukan di daerah ini sehingga menarik untuk diteliti lebih lanjut. Penelitian ini bertujuan untuk menget...
A geological study was conducted in Kulon Progo and its surrounding areas (Kulon Progo and Purworejo Regency). It focused on regional geology, tectonic configuration, geodynamics and magmatism, lithology and volcanology, and mineralization. Although there has been considerable research of mineralization in the area—particularly in Kokap (Kulon Prog...
Abstrak Penelitian terletak di daerah Bayat, dan Gunungkidul yang merupakan pusat studi geologi yang menarik. Kehadiran batuan beku, metamorf, dan karakter dari sebaran serta bentukan morfologi yang unik menjadikan ketertarikan peneliti untuk mengkaji Bayat dengan konsep di luar pakemnya dengan tujuan memahami kehadiran kaldera dalam kaitannya deng...
Daerah Godean merupakan bagian dari vulkanisme Miosen, yang tersisa pada daerah Yogyakarta bagian tengah. Vukanisme pada daerah Godean, diperkirakan sebagai produk dari busur gunungapi kepulauan dengan diferensiasi yang terbentuk mulai dari andesit basaltik, andesit dasitik, dasit, riodasit, dan kembali menjadi andesit basaltik. Penelitian dilakuka...
Research on precious metals mineralization has not been done yet in the central part of Yogyakarta. Yogyakarta Basin which is dominated by Quarterly deposits of Merapi Mountain product, Tertiary carbonate sediment rock and igneous rock in Godean area. Potential of mineralization can be seen in the characteristics of igneous rocks, the condition of...
Godean hills is located approximately 10 km westward from the Yogyakarta City. The landscape of Godean hills and plains is affected by various factors, such as lithology, geological structure, and sub-aerial process. The purpose of this study was to reveal the landscape of Godean. The method consisted of field study, morphological variables assessm...
Daerah Godean merupakan daerah perbukitan yang terdiri dari batuan beku yang diikuti oleh adanya alterasi hidrotermal dan pelapukan batuan yang cukup intensif. Litologi daerah Gunung Wungkal terdiri dari Andesit dasitik sampai dasit hornblenda, yang teralterasi lemah (klorit-pirit ) sampai kaolinit-smektit kuat kemudian terlapukan. Perubahan batuan...
Cijulang prospect is located in Talegong Sub-District of Garut Regency, West Java, Indonesia. The prospect is characterized by enargite-gold mineralization and associated acid sulfate alteration. Mineralization is hosted by Tertiary calc-alkaline volcanic and volcaniclastics rocks. Fluid inclusions were studied in order to constrain the temperature...
Sualan prospect is located at Talegong Sub-district of Garut Regency, West Java, Indonesia. The area constitutes calc-alkaline volcanic and volcaniclastic rocks of Tertiary age. The rocks have experienced regional propylitic and argillic alteration. Fluid inclusions from quartz veins were studied in order to constrain the nature, characteristics an...
Cijulang is a high-sulfidation epithermal system hosted in the calc-alkaline rocks of andesite lava and lapilli tuff. Mineralization in the prospect is characterized by pyrite-enargite-gold and associated acid sulfate alteration. Studies on ore and gangue mineral assemblages and their mutual textural relationships were carried out in order to explo...
