| Judul Artikel | GEOLOGI DAN STUDI ALTERASI DAERAH MANDIRANCAN DAN SEKITARNYA KECAMATAN PATIKRAJA KABUPATEN BANYUMAS JAWA TENGAH |
| Abstrak (Bhs. Indonesia) | Daerah penelitian terletak di wilayah Mandirancan dan sekitarnya, Kabupaten Banyumas, Jawa Tengah, itu didominasi oleh breksi andesit perselingan lava andesit dan sisipan batupasir, batupasir, dan aluvial.Breksi andesit dan batupasir; telah mengalami altersasi dan mineralisasi .Fisiografi daerah penelitian masuk dalam Pegunungan Serayu Selatan. Berdasarkan kondisi di lapangan batu beberapa sampel yang telah dikumpulkan, umumnya telah mengalami altersai. Zonasi alterasi di daerah penelitian terdiri dari klorit-epidot-kalsit-kuarsa; klorit-montmorillonit-kuarsa-karbonat; kuarsa-halloysit-illite. Berdasarkan mineral-mineral yang terdapat di ketiga zona tersebut didapatkan temperatur50ºc - 300ºc; dengan ph basa-netral. Dapat disimpulkan daerah penelitian mengalami mineralisasi dengan tipe epitermal |
| Abtrak (Bhs. Inggris) | The study area is located in Mandirancan and surrounding area, Banyumas Regency, Central Java, it is dominated by andesite breccias interlude lava andesite and insertion sandstone, sandstone, and alluvial. Andesite breccias and sandstone; which have undergone mineralization and hydrothermal alteration. Fisiography of the study area is part of Southern Mountain of Serayu. Based on the field observation of some rock samples which have collected from surface area, the study area generally had undergone alteration and mineralization. Alteration zone in the study area have contains of chlorite-epidote-calcite-quartz; chlorite-montmorillonite-quartz-carbonate;quartz-halloysite-illite. Based on mineral assemblages have occured on third zone of hydrothermal alteration in the study area was occured within temperatures about 50oC - 300oC; with pH neutral to basa. So that the study area have undergone alteration and mineralization more than one time with mineralization type epithermal. |
