Abstract

Pacitan area is known as Tertiary volcanic arc in Java, as the result of subduction zone of the Indian-Australian Plate beneath the Eurasian Plate since Oligocene. It was superimposed volcanism which formed a wide area of hydrothermal alteration zone, resulting potential ore metals mineralization, such at Temon and its vicinities, Pacitan Regency, East Java Province, Indonesia. The aim of study was to analyze hydrothermal alteration and ore metal mineralization zones. Method was surface mapping, thin section analyses, mineragraphic analyses and X-Ray Diffraction (XRD) analyses. Field study observed denuded and deformed volcanic crater geomorphology. There are ore placer deposits within the sand dunes of Grindulu River, which it consists of andesitic lava and breccia of Early Oligocene Mandalika Formation; Early Miocene lithic and vitric tuffs; and dacitic intrusion. The dikes of dacite as the last of volcanism was the host rock controlling the zonation of alteration and mineralization stages. Oblique normal faults and shear faults were cross over dilating formed fractures, which were as bodies to depositing the ore metals. There are (zone 1st) the argillic clay consists of quartz+alunite+dickite+kaolinite±illite with vuggy structures, (zone 2nd) the argillic clay consists of quartz+montmorillonite±illite zone with quartz vents, brecciated and sulfide massive, and (zone 3rd) as the chloritized zone with low grade and supergene on the edge of hydrothermal alteration. It was fluid overprinted that very acid to the core of zone 1st (pH2-4) into more netral pH 4-6 (zone 2nd) and (pH5-6) in the edge zone 3rd. The potentials ore metal mineralization are Fe and Cu by pyrite, chalcopyrite, hematite, and covellite. Other potential ore metal mineralization was also from enargite by the supergene alteration.

Abstract

Pacitan district have an interesting anomaly. Every time mostly impacted by disaster especially landslide. Landslides in their various forms are common hazard in mountainous terrain, especially in seismically active areas and regions of high rainfall. Landslides are one of the most common natural hazards in the Southern Range East Java terrain, causing widespread damage to property and infrastructure, besides the loss of human lives almost every year. The aim of this study predicted the potential landslide using Weight of Evidence Method. The geological data used lithological data, structural data, contour data and, alteration. Results from this data analysis are six evidence maps, such as NE-SW lineament, NW-SE lineament, host rock, heat source, kaolinite alteration and iron oxide alteration maps. The geophysical data analysis the distribution of rock density to interpretation the landslides. Evidence maps were analyzed by weight of evidence methods to result in favorable maps where the validity was tested using conditional independence (CI), the pairwise and overall tests. Then, the analyses produced a posterior probability map of the landslide. Posterior probability map (mineral potential maps) was validated by checking field. Posterior probability map (after validation) or favorable map predicted approximately favorable zone and non-favourable zones. Favorable zones of Potential Landslide Hazard Zonation, are divided into three classes. They are high-potensial hazard, moderate hazard and low hazard.

Abstract

The research area is located in the area of Mount Gembes, Jeruk Village in Pacitan (East Java). This study aims to determine the characteristic and temperature in the formation of alteration which refers to petrography with the help of samples taken in the study area. The petrographic observations carried out were thin section observations which were then analyzed for the mineral content contained in the sample rock. After knowing the minerals contained in the sample rock, it is then entered into the mineral formation temperature diagram (White & Hedenquist, 1995). The method used in this study includes primary data in the form of geological observations such as lithology, geological structure geomorphology, environmental geology and alteration observations and combined with secondary data. Alteration observations in this study were carried out descriptively (megascopic) and subjective (microscopic). The geomorphic unit that works is of volcanic origin, with high hilly sub-units of porphyry dacite intrusion (volcanic neck). Geological structures that develop in the study area are faults, namely the left horizontal fault of Jeruk 1, the left horizontal fault of Jeruk 2 and the interpretation of the oranges right horizontal fault. Geological resources or sources found in the research area are mineral potential resources that are economical, and negative sources are in the form of mass movement of debris flow type. The Zonation and the type of alteration that developed in the research area are the clay alteration zone and silicification. The clay zone is formed at a temperature >100⁰C-220⁰C with a pH of 3-5 and a silicification zone is formed at a temperature>100⁰C-300⁰C with a pH <2 which is directly controlled by the faults found in the study site.

Abstract

Research on the estimation of groundwater potential and its depth has been carried out in Nglanggeran Kulon which is the Nglanggeran Ancient Volcano Tourism Village in Gunung Kidul. The large number of tourists who visit makes the need for groundwater in this location also increases but has not been matched by its availability. This area is also a district that almost every dry season experiences a water crisis. The purpose of this study was to find out the potential presence of groundwater and its depth. This is related to the efforts of local residents who want to build new wells. The method used is the geoelectric resistivity method with the Shlumberger configuration. This method exploits the electrical properties of the rock beneath the surface. The physical parameter measured is the resistivity value to create a subsurface geological model in the form of a 1D model. The length of the stretch carried out is 125 m at two measurement points. The results of this study indicate that 1st point has two layers of rock and no groundwater potential is found. 2nd point has four layers of rock. Groundwater potential is found in 2nd layer because it has a low resistivity value of 9.89 ꭥm at depths ranging from 5-9 meters with a thickness of about 4 meters. So that the location of the 2nd point is more recommended for making new wells.

Abstract

Kabupaten Pacitan merupakan wilayah dengan tingkat bahaya longsor paling tinggi di Provinsi Jawa Timur, salah satunya di Desa Kasihan Kecamatan Tegalombo. Secara umum daerah ini tersusun oleh batuan sedimen klastik, batuan vulkanik, dan batuan-batuan terobosan. Secara fisiografi daerah penelitian termasuk dalam Zona Pegunungan Selatan yaitu Zona Bagian Selatan Jawa Timur. Zona ini mempunyai topografi yang terjal. Bagian selatannya berupa dataran eolian yang tersusun oleh endapan aluvial, batugamping dan batuan vulkanik. Tingginya kejadian longsor pada wilayah tersebut dipengaruhi oleh beberapa faktor, beberapa diantaranya yaitu tingkat pelapukan, jenis litologi, kondisi geologi dan faktor-faktor lainnya. Telah dilakukan pengukuran sebanyak dua lintasan dengan panjang 560 meter di daerah penelitian dengan target kedalaman sekitar 200 meter di bawah permukaan. Berdasarkan hasil interpretasi data, daerah tersebut memiliki nilai resistivitas rendah sekitar 20-50 Ωm yang diduga berupa batuan yang telah mengalami pelapukan tinggi dan atau mengandung air. Ketebalan lapukan ini sekitar 100 meter serta berada di sekitar atau bahkan di atas batuan dengan resistivitas tinggi 500-1200 Ωm. Batuan ini diduga berupa batuan vulkanik yang belum lapuk serta berperan sebagai bidang gelincir saat lapisan lapuk diatasnya terisi oleh air di musim hujan sehingga terjadi longsor.Kata kunci : longsor, dipole-dipole, tegalombo pacitan

Abstract

The research area is located in Mangunharjo-Grindulu, Pacitan (Indonesia), as part of the Southern Mountain Tertiary Volcanic Arch. Outcrops of quartz veins-riched volcanic rock associated with sulfide minerals are found in this area. The Southern Mountain Oligo-Miocene magmatic arc is known as the potential area that contains precious metal deposits. The study aimed to determine the characteristics of the mineralized zone in this area. The research methods are geological surface mapping, thin-section observation, mineragraphy, and X-Ray Diffraction (XRD). The results show that the constituent lithologies were andesitic lava, breccia, and tuff; co-ignimbrite breccia, dacitic pumice and tuff, and dacitic dike; and pyroxene-rich andesitic volcanic rocks. The geological structure is dominated by oblique normal faults, strike-slip faults, and upward oblique faults associated with shear joints filled with quartz veins. Fieldwork observation, thin-section analyses, and mineragraphic and XRD observations identify three alteration zones in the hydrothermal system: the advanced argillic zone, the intermediate argillic zone, and the chloritized zone. By the mineral’s association, it is interpreted that the advanced argillic zone was formed at a temperature of 220-330oC and pH 3-6 due to dissemination with side rocks located near the hydrothermal flows; the intermediate argillic zone and the chloritized zone were formed at a temperature of 150-300oC and a pH of 5-6 due to chloritized alteration of the hydrothermal fluid carrying the ore. This alteration zone has no economic potential for precious metal minerals so it is better to be developed for education, conservation, and natural laboratories.

Abstract

Daerah Kabupaten Pacitan, areanya termasuk di dalam pegunungan selatan Jawa Timur, kaya akan kandungan mineral tembaga dan logam lainnya. Area berada di Kecamatan Ngadirojo, konsesi perusahaan PT.Gemilang Limpah Internusa, salah satu perusahaan yang bergerak di bidang industri pertambangan tembaga, dimana dalam produksinya menghasilkan Air Asam Tambang yang berpotensi mencemari sungai warga karena tambang ini terletak di hulu sungai. Menurut asal usul dan genesa, terbentuknya mineral logam, termasuk tembaga di dalamnya, terjadi karena proses hydrothermal di dalam permukaan bumi. Situasi ini yang menjadi sebab kegiatan eksploitasi terhadap mineral tersebut dan penyertanya menimbulkan adanya dampak perubahan kondisi lingkungan. Eksploitasi ataupun pengambilan material tersebut juga membuat kualitas dari air tanah sekitar memburuk. Saat ini perusahaan masih menggunakan metode cara lama, dengan menggunakan serbuk kapur tohor dalam mengikat polutan/limbah yang muncul. Metode elektrokoagulasi merupakan salah satu metode alternatif dalam mengelola air asam tambang, sehingga diharapkan tingkat kerusakan lingkungan dengan metode ini bisa menurunkan tingkat pencemaran dengan lebih baik. Dari beberapa percobaan, dengan waktu tertentu, semakin lama waktu aliran listrik, semakin baik tingkat penjernihan air asam tambang. Sehingga waktu yang diperlukan bisa dipercepat sebelum air masuk ke sungai. Elektrokoagulasi juga dapat sebagai alternative cara yang lebih efisien dan cepat  untuk menetralkan air asam tambang selain dengan kapur tohor

Abstract

Research has been carried out on the existence of slip surfaces in Wanurejo, Borobudur District, Magelang Regency, Central Java. The location of the slip surface is identified using the resistivity method of the dipole-dipole configuration. This research was conducted at a relatively flat measurement location and at an altitude of around 95–105 meters above sea level. Measurements were made on 6 different lines with a length of track 1 of 250 m. The results of data processing indicate that the layer that acts as a slip surface is a layer of clay. The clay layer has a resistivity value ranging from 15 to 35 ohm.m, which is relatively thin, so it has the potential to become a slip surface because it is located between two rocks that have a significant resistivity contrast: compact andesite rock and water-saturated sandstone. If the water-saturated sandstone layer is no longer able to withstand the weight above it, the surrounding andesite rocks will easily slip. This is also reinforced by the presence of a layer of clay that is slippery, so the potential for landslides or slipping is greater.
