摘要

摘要为寻找茂物卡林金地区的砂岩矿床，进行了直流电阻率 2D 测量。温纳阵列共有 1 个外露点和 5 条电极间距为 10 米的测量线，用于测量每条长度为 470 米的测量线。然后将测量获得的二维数据插值到三维横截面上，可以看出挖掘沙土的潜力在地表以下 10 至 20 米处，厚度为 30 至 40 米。根据 ROCKWORKS20 软件演示版中的体积等值面处理，在实地共发现 1,005,711 立方米的砂岩。摘要二维直流电阻率勘探是为了确定茂物 Caringin 区的黑砂矿床位置。采用温纳配置（1 个露头和 5 个测量轨迹，电极间距为 10 米），每个测量轨迹的长度为 470 米。然后将测量获得的二维数据插值到三维横截面上，结果显示，可挖掘的潜在沙地位于地表下 10 至 20 米处，厚度为 30 至 40 米。根据 ROCKWORKS20 软件演示版中的等表面积处理，该区域共有约 1,005,711.0 立方米的黑砂。

PEMODELAN 2.5 DIMENSI (2.5D) UNTUK DEPOSIT PASIR MENGGUNAKAN DATA DC RESISTIVITY 2D PADA DAERAH KECAMATAN CARINGIN BOGOR

Abstract. DC Resistivity 2D has been carried out to find sandstones deposits in Caringin District, Bogor. Wenner array with a total of 1 outcrop and 5 measuring lines with 10m spacing between electrodes was used to measure the length of each 470m length lines. The 2D data obtained from the measurements are then interpolated into a 3D cross-section and it can be seen that the potential for excavated sand is 10 to 20m below the surface with a thickness of 30-40 meters. A total of 1.005,711 cubic meters of sandatones are found in the field based on Volume Isosurface processing in the Demo version of ROCKWORKS20 software. Abstrak. DC Resistivity 2D telah dilakukan untuk mencari deposit pasir hitam di Kecamatan caringin Bogor. Konfigurasi Wenner dengan tital 1 lintasan singkapan dan 5 lintasan pengukuran serta digunakan spasi antar elektroda 10 m untuk mengukur panjang lintasan masing-masing 470 m. Data 2D yang didapat dari pengukuran kemudian diinterpolasi ke dalam bentuk penampang 3D dan terlihat potensi pasir yang dapat digali berada 10 hingga 20 m di bawah permukaan dengan ketebalan 30- 40 meter. Total sejumlah kisaran 1.005.711,0 meter kubik pasir hitam terdapat di lapangan berdasarkan pengolahan Volume Isosurface di software ROCKWORKS20 versi Demo.
