Baskoro, Jayeng (2008) Penentuan Sebaran Urat (Vein) Pyrite dengan menggunakan Metode Geolistrik Resistivitas Mise a la masse di Daerah Bangkong-Gadjahrejo Gedangan Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Telah dilakukan penelitian untuk menentukan sebaran urat ( vein ) pyrite pada tanggal 24 September - 8 Oktober 2005 di daerah Bangkong-Gajahrejo Gedangan Malang Selatan, dengan menggunakan metode geolistrik resistivitas mise a la masse . Akuisisi data dilakukan dengan menggunakan alat resistivitymeter ABEM SAS 300. Area penelitian yang digunakan seluas 560 m x 560 m (0.3 km2). Area ini dibagi ke dalam bentuk grid titik-titik pengukuran. Pengambilan data dilakukan dalam lima belas lintasan ( line ), Jarak antar lintasannya 40 meter dan jarak antar titik pengukuran 40 meter. Data hasil pengolahan dikonturkan dengan menggunakan perangkat lunak surfer versi 8 untuk mendapatkan kontur resistivitas semu dan kontur potensial diri. Kontur resistivitas diinterpretasi untuk mendapatkan letak dari tubuh urat pyrite dan sebaran dari cabang-cabang urat pyrite , kontur potensial diri diinterpretasi dengan metode pendekatan lempeng dua dimensi untuk mendapatkan target kedalaman. Berdasarkan hasil interpretasi didapatkan lokasi tubuh urat pyrite yang merupakan akumulasi terbanyak terletak pada titik ukur 242, 250, 322, dan 328, yang mencakup luasan sekitar (3 x 40 m) x (6 x 40 m) = 120 m x 240 m =2.88 x 10-2 km2. Sedangkan distribusi akumulasi mineral sulfida pyrite yang relatif kecil, terletak dibagian utara dari base yang dibatasi oleh titik-titik ukur 507, 510, 456, dan 458 yang mencakup luasan (2 x 40 m) x (3 x 40 m) = 80 m x 120 mm = 9.6 x 10-3 km2. Penyebarannya berkembang ke arah utara selatan dan timur barat terhadap titik base , dengan kedalaman antara 66 m sampai dengan kedalaman 112 m.
English Abstract
The aim of this research was to determine the distribution of pyrite vein at Bangkong-Gajahrejo Gedangan the south of malang. The research was conducted from September 24 to Oktober 8, 2005 used mise a la masse geoelectric resistivity methods. Data acquisition was conducted using resistivitymeter ABEM SAS 300. The observed area about 560 m x 560 m (0.3 Km2), then was divided into grid points of measurement. The data were taken from 15 lines, with the distance between lines 40 m and the distance between point of measurement was 40 m. After processing, the data were processed using the software surfer version 8 to obtain a resistivity and potential contour. From the results; the resistivity was used to obtain the position of a pyrite body and the distributions of the branches, and the potential was used to interpreted the depth of the target. Based on the interpretation at the result, a location of the highest accumulation of the vein pyrite body was located at the point 242, 250, 322, and 328 which included area about 2.88 x 10-2 km2. And the lowest accumulation were distributed at north side of base that bordered by point 507, 510, 456, and 458 which covered area about 9.6 x 10-3 km2. The distribution was expanded to the north, south and east, west direction from the base, with 66 m and 112 m in depth.
