Abstract

Daerah panasbumi Gunung Sumbing terletak di Desa Renah Kemumu, Kecamatan Jangkat, Kabupaten Merangin, Provinsi Jambi pada ketinggian ± 900 mdpl. Keberadaan manifestasi panasbumi di lokasi penelitian diduga belum terpetakan seluruhnya. Untuk mengidentifikasi sebaran manifestasi panasbumi dapat menggunakan Citra Landsat 8 berdasarkan sensor TIRS pada band 10. Akuisisi data geolistrik menggunakan konfigurasi dipole-dipole dilakukan sepanjang manifestasi air panas dan tanah beruap dengan panjang lintasan 750 m dan spasi elektroda 25 m. Penelitian ini bertujuan mendapatkan sebaran manifestasi panasbumi berdasarkan suhu permukaan tanah dari Citra Landsat 8 dan mendeskripsikan lapisan batuan bawah permukaan dalam menganalisis karakteristik hot springs flow berdasarkan metode geolistrik. Suhu permukaan tinggi berkisar 21-30°C berada di bagian baratdaya daerah penelitian. Hasil pengukuran geolistrik menunjukkan fluida hidrotermal dengan resistivitas 5 – 40 Ωm. Hal itu dikarenakan fluida hidrotermal berasosiasi dengan batuan alterasi sehingga bersifat konduktif. Aliran fluida hidrotermal teridentifikasi pada kedalaman 0 m hingga 25 m. Berdasarkan integrasi data geologi, faktor pengontrol adanya manifestasi mata air panas disebabkan oleh segmen Sesar Dikit dan batuan Vulkanik di daerah penelitian.Katakunci: Citra Landsat 8, metode geolistrik, panasbumi, hot springs flow.

Abstract

This paper presents a review of several published seismic reflection and seismicity data and analyzes of high-resolution bathymetry data to revise the exact location and reveal detail characteristics of a strike-slip fault zone that formed the southernmost segment of the Sumatran Fault (SF). Previous works interpreted this fault segment as a horst structure to the south of a pull-apart basin. We observe a clear linear trace of dissected seafloor parallels to SF in the high-resolution bathymetric map. This structure extends from the south of a pull-apart basin in the northwest to the Sunda accretionary wedge farther southeast. This lineament exhibits a narrow valley and a linear ridge that in the subsurface are interpreted as negative and positive flower structures, respectively. The structure exhibits a vertical fault plane and appears to have deformed the accretionary wedge sediments and basement at depth. A cluster of shallow seismicity is observed along this NW-trending fault zone, indicating the activity of this zone. Here, we proposed this strike-slip fault as the Ujung Kulon Fault that marks the southeasternmost segment of the SF zone. This segment deformed the area of the Sumatra-Java forearc basin and terminated in accretionary wedge near the trench. The accumulated strain within UKF may trigger large earthquake in the future, close to the highly populated areas in the coast of Sumatra and Java.Keywords: Strike-slip fault, Sumatra Fault, Ujung Kulon Fault, segmentation, earthquake.

Abstract

Land movement occur because of the movement of slope-forming material such as of soil, rock or a combination of material types to a place that is lower due to the influence of gravity. The movement of slope material can be identified by the Electrical Resistivity Tomography (ERT) Method, because this method has good lateral and vertical resolution based on rock resistivity data. The trigger factors for land movement in Anjung Village, Pasanggrahan Baru, South Sumedang, among others: an increase in water content on the slopes and the slip plane. Increased water content is influenced by infiltration of rainwater as one of the triggers of land movement,  can be detected by the Self Potential method (SP), while the slip plane can be detected by the method of Electrical Resistivity Tomography (ERT). Based on the results of the ERT and SP measurements, the results are: debris flow as a landslide plane (resistivity values: 31 – 170 Ohm.m and SP values: 5 – 13 mV), water table/water saturated layer (resistivity values: 1 – 13 Ohm.m and SP values: 14 – 34 mV), and breccias (resistivity values: 400 - 900 Ohm.m and SP values: 1-3 mV).Slip plane are estimated to be at boundary between the breccia and the material on it.Keywords: Land movement, resistivity, self potential, South Sumedang

Abstract

The Karangsambung Formation in Kebumen, Central Java is olisostrome deposit that composed of floating rock fragments in the claystone matrix. The age of this formation is still debatable, and it is even unclear that the present age was the age of the formation or the age of the source rock of the olisostrome sediment. In this study, the relative age of the source rock of the olisostrome sediment was identified by using foraminifera data. The relative age identification of the olisostrome source rocks are very important as the identification of olisostrome sediment age is very difficult. The relative age of Karangsambung Formation can be assumed younger than the age of the olisostrome source rocks. Result of Karangsambung Formation age identification with regard to the olisostrome concep will have implications to the regional tectonic model of Java.Keywords: Karangsambung Formation, relative age, source rock, foraminifera, olisostrome.

Abstract

Konfigurasi batuan alas di bagian utara Pulau Misool belum memberikan informasi adanya pola struktur geologi seperti yang berkembang di bagian selatan. Dengan demikian diperlukan adanya kajian yang bisa memperkirakan keberadaan struktur geologi yang diduga berkembang ke arah utara. Data gaya berat yang telah diperoleh di P. Misool diharapkan dapat memberikan informasi terkait keberadaan pola struktur geologi.Berdasarkan anomali gaya berat diperoleh adanya nilai tinggi di bagian selatan dan membentuk punggungan anomali berkorelasi terhadap jalur antiklin Missol-Onin. Anomali bernilai rendah membentuk cekungan anomali di bagian utara P. Misool dan merupakan bagian Cekungan Salawati. P. Missol di bagian utara ditempati oleh batuan Kuarter yang menutupi struktur geologi. Nilai anomali gaya berat berkisar antara 50 sampai 105,5 mGal membentuk zona punggungan dan rendah anomali. Analisis dengan metode SVD digunakan untuk mempertegas zona depocenter yang telah diperoleh. Model geologi berdasarkan penampang anomali gaya berat diperoleh tiga nilai rapat massa yang mendeskripsikan tiga lapisan batuan sedimen yang berbeda.Katakunci: Pulau Misool, SVD, sub-cekungan, anomali, gaya berat.

Abstract

Kuroko-type VMS (volcanogenic massive sulfide) ore deposit is a deposit that has some abundant sulfide minerals such as pyrite, chalcopyrite, galena and sphalerite. Besides them, other common sulfide minerals also occur, such as bornite, acanthite (argentite) and some of tennantite-tetrahedrite series. In some cases, we can find sphalerite and pyrite on these deposits. These cases often make the difficulty of XRD analysis. It is caused by some overlapping diffraction peaks between pyrite and sphalerite, which are difficult to be distinguished. This problem can cause miscalculation of weight fraction between them. Therefore, this study was done in order to make sure the true phase between pyrite and sphalerite of the overlapping diffraction peaks. Cubic structure analysis and precise lattice parameter calculation were used as the method in this study in order to determine the true phase of sphalerite-pyrite overlapping peaks. An XRD analysis on the case study sample shows that there are five cubic planes, i.e. (111), (200), (220), (113), and (222) on some overlap diffraction peaks. By utilizing this method, these cubic planes can be distinguished where (111) and (113) are pyrite phases while (200), (220) and (222) are sphalerite phases.Keywords: Kuroko, sphalerite, pyrite, XRD, precise lattice parameter.

Abstract

The Paleogene carbonate unit in the North West Java Basin has no cropped out and never been shown in the regional stratigraphy, whether as a formation or as a member of the existing formation. This paper provides new insight of the diagenetic process evidence by the stable isotope of 2H and 18O in formation fluids integrated with petrographic and geochemical data of rock and fluids samples analysis. The major minerals of this carbonate unit are: calcite, clay minerals, dolomite, quartz, plagioclase, and pyrite. From ICP-OES analyses result this carbonate rocks has the content of Fe, Mg and Al ranges 450-7800 ppm, 497-10892 ppm and 96-3900 ppm respectively, while Si and Sr are relatively low around 0.1 ppb to 0.7 ppm and 60 ppm to 570 ppm respectively. Formation water chemistry data shows the total charges for cation and anion were relatively balanced from 75.5 to 396.8 meq, the TDS from 4,904 mg/l to 22,351 mg/l, and SG from 1.005 to 1.016 and were dominated by elements of Na, Ca, Mg, Cl and HCO3. The δ2H and δ18O from water samples are between -26.2 to -37.2 (‰) and between -3.63 to 2.50 (‰) respectively. With all the correlation of geochemical and isotope data of both rock and water indicate that the Paleogene Carbonate system in the M-Field has been through at least once uplifting and one sea water rise/drowning event, with meteoric water affected diagenetic process. These geological processes shown by the calcite cementation, the presence of pyrite and quartz, recrystallization of the carbonate grains and mylonitic dolomite, high content of Mg, Fe and Al, and also the abruptly change of the δ13C and δ18O values.Keywords: Paleogene carbonate, geochemistry, water chemistry, stable isotope, diagenesis.
