Komplek Gunungapi Dieng termasuk salah satu gunungapi aktif di Indonesia, berdasarkan hal tersebut di atas maka Seksi Vulkano Fisika, Sub Direktotat Analisa Gunungapi melakukan penyelidikan geomagnet guna mengathui pola kemagnetan di daerah ini.
The magnetotelluric method is one of many methods based on measuring the electrical resistivity of the subsurface as an indirect means for studying geology, but it is a method that caught the imagination of many explorations when it was first described nearly three decades ago by Cagniard and Tikhonov.
Magnetic, gravity, resistivity and refraction seismic surveys were made in a 2.5 km2 coastal area of titaniferous magnetite sand deposits at Meleman village, East Java. Magnetic anomaly data are consistent with models having an average susceptibility of 2.5 x 10 emu/cm? and negligible remanent magnetization with shapes of observed dunal topography or buried lens…
The impetus for publishing this set of articles was the realization that, year after year. I and my students at Stanford were making copies (with varying degrees of legibility and legality) of the same classic articles on plate tectonics and geomagnetic reversals. At first we did this because there was so little material on the subject available.
This paper discusses one of the successful application of induced polarization (IP) and magnetic methods to an epithermal gold prospect of Mt. Subang, West Jawa, Indonesia. The main host-rock for the metallic minerals in the epithermal gold deposit of Mt. Subang is an altered andesite. In this case study, therefore, the magnetic method is used to map the zone of altered andesite and to confirm …
Telah dilakukan pengolahan data hasil pengukuran medan maget total di daerah Gunung Dieng, Kabupaten Banjarnegara, Jawa Tengah. Pengolahan dilakukan dengan pemisahan anomali medan magnet regional dan anomali mdan magnet residual menggunakan pengolahan moving avarage.
The statocone of Mt. Cemara Lawang is part of The Mt. Bromo-Tengger volcano complex, East Java, Indonesia. Mt. Cemara Lawang is comosed of a sequences of deposits, comprising the big feldspar lava, andesite lava, phreatomagmatic ash fall, phreatic, basalt lava, basaltic andesite lava, andesite lava, alternating layers of pyroclastic fall and flow and the brown ash fall deposits from the oldest …
Attire par magnetisme des Roches puis rapidement par les applications du magnetisme a la volcanologie et a la sesmogenese, j'ai trouve au fil des annes a L'IPGP puis, a l'exterieur, des cooperations scientifiques et techniques qui m'ont permis de developper mes travaux.
The study that is reported here focuses on the palaeomagnetism of late Archaean flood basalts and the implications for geodynamic and geomagnetic processes during a part of this interval of early Earth history.
Kompleks Volkanik Ijen berada di Kabupaten Banyuwangi, Jawa Timur, Indonesia, terdiri dari kaldera besar dengan luas 252 km, yang di dalamnya terdapat lebih dari 15 pusat erupsi. Diantara pusat erupsi tersebut, Kawah Ijen merupakan satu-satunya pusat erupsi yang masih aktif.
