Abstract

Kecamatan Lumbir, Kabupaten Banyumas mempunyai sumber daya mineral non logam berupa lempung dan sumber daya batuan berupa andesit dan batupasir. Analisis sebaran, jenis, dan kualitas diperlukan untuk optimasi pemanfaatan sumber daya alam tersebut. Analisis laboratorium meliputi analisis XRD (X-Ray Diffractometry), XRF (X-ray Fluoroscence) dan analisis kuat tekan batuan. Analisis XRF menunjukan lempung di daerah Lumbir mempunyai unsur SiO2 yang tinggi (berkisar antara 39 – 54,5 %) sehingga dapat dijadikan bahan campuran dalam pembuatan semen, gerabah kasar, dan batu bata. Sumber daya batuan berupa andesit di Desa Canduk dan Desa Parung Kamal memiliki nilai Kuat Tekan Ultimit (qu) berkisar antara 247,7547 kg/cm2 - 45,4674 kg/cm2, sehingga dapat digunakan sebagai batu hias dan batupasir di Desa Karanggayam dapat dijadikan tanah urug

Abstract

The structure of Exia is composed of Miocene built-up carbonates formed by shear faults. The buildup carbonate feature in the Exia prospect can be seen from the high elevation surrounded by lows with an NNE-SSW and NE-SW trending. The MA-1, SE-1, MI-1 wells are several wells in the Tiaka and Senoro Fields which are proven to have large gas reserves. Tiaka Field is located to the west of the Exia Well, while Senoro Field is to the northeast. The study used primary data from the Exia-1 well in the form of cutting samples. The wet and dry cutting samples were further processed into thin section. This thin section is then carried out for petrographic, XRD, and SEM analysis. Tomori Formation starts from the deeper environment FZ1 upwards to the shallower FZ5 –FZ6 (reef) with open marine and restricted areas. The allochem that composes the limestone at The Matindok Formation consists of red algae fragments and benthic forams which indicate the facies zone of formation in FZ 4 (slope). In the upper Mantawa Formation, it is still quite clear the presence of large forams indicating a reef association environment (FZ5-FZ6), but the presence of a large number of planktonic forams indicates a deeper depositional environment / slope, so it is possible that large forams were transported from a shallower environment. The Kintom Formation have rock provenance ranging from continental blocks in the interior of the craton to a recycled orogeny section of recycled quartz zone.
