MENGHITUNG DAN MEMISAHKAN BATUAN VULKANIK DARI DATA GEOLISTRIK DALAM 2-D DAN 3-D

Untuk menghitung dan memisahkan batuan vulkanik dari data geolistrik, ada beberapa metode yang dapat digunakan, di antaranya:

1. Metode Electrical Resistivity Tomography (ERT): Ini adalah metode survei geofisika yang memanfaatkan prinsip resistivitas elektrik untuk membuat profil subsurface. Data resistivitas dapat digunakan untuk menentukan komposisi batuan vulkanik dari data geolistrik.
2. Metode Induced Polarization (IP): Ini adalah metode survei geofisika yang memanfaatkan prinsip polarisasi yang diterapkan pada bahan geologi untuk menentukan mineral-mineral yang ada. Data IP dapat digunakan untuk memisahkan batuan vulkanik dari data geolistrik.
3. Metode Magnetotelluric (MT): Ini adalah metode survei geofisika yang memanfaatkan variasi medan magnet dan medan elektromagnetik untuk menentukan konduktivitas subsurface. Data MT dapat digunakan untuk memisahkan batuan vulkanik dari data geolistrik.

Ketiga metode ini memerlukan pemahaman yang baik tentang geologi dan fisika subsurface untuk menentukan interpretasi yang tepat dari data geolistrik. Oleh karena itu, biasanya dilakukan dengan kerja sama antara ahli geologi dan ahli geofisika.

Model Akuifer Air Tanah dengan Metode Geolistrik

Identifikasi Rembesan Air Laut atau Abrasi di Area Dekat Laut dengan Metode Geolistrik

Dalam metode geolistrik, nilai resistivitas batuan yang mengandung air atau porositasnya tinggi akan terlihat jelas dibandingkan dengan batuan yang relatif kompak. porositas suatu batuan akan terisi oleh fluida yang mengisi kekosongan tersebut baik air atau cairan lain yang ada di bawah permukaan. Area dekat laut akan memungkinkan batuan yang berporotas tinggi ini akan menyerap air yang dari air laut dan mengendap di dalamnya dan karakternya akan berbeda dengan air yang bukan air laut (air tawar).

Dalam kaitanya dengan bangunan, air laut akan mengakibatkan korosi atau menjadikan bangunan tidak tahan lama sehingga perlu dilakukan penanganan khusus untuk menghambat korosinya. Identifikasi air laut atau abrasi dengan metode geolistrik akan memperlihatkan nilai resistivitas yang cukup kecil yang biasanya di bawah 10 ohm.m atau bahkan sampai nol koma ohm.m.

Model di bawah merupakan penampang 2-D data geolistrik yang memperlihatkan sebaran nilai resistivitas. Warna biru merupakan kandungan air laut yang terdapat di bawah permukaan dengan karakter yang khas yaitu ada jalur dari permukaan dan di salurkan ke tempat lain dan di endapkan di bawah permukaan.

Investigasi Sumber Mata Air dengan Metode Geolistrik GeoResist

metode geolistrik membantu menginvestigasi adanya sumber mata air, air permukaan ataupun akuifer yang ketiganya mempunyai ciri khas baik dalam karakter strukturnya atau lokasi keberadaanya.

Alat yang digunakan menggunakan alat single channel dengan dibuatkan switchbox sehingga bisa dilakukan pengukuran 2-D. Injeksi arus listriknya dilakukan secara manual tetapi akurasinya tidak jauh berbeda jika alatnya rutin di kalibrasi dengan alat-alat yang lebih bagus sensitifitasnya. Sebelum dilakukan pengukuran dilakukan terlebih dahulu survey tinjau untuk melihat struktur, pola sedimentasi dan topografinya sehingga kita bisa mengklasifikasi model air apa yang terkandung di bawah permukaan.

DI SEWAKAN DAN SPESIFIKASI SUPERSTING RESISTIVITY-IP METER R8

Product Details

Item	Description
Measurement Modes	Apparent resistivity, resistance, induced polarization (IP), SP, and battery voltage.
Measurement Range	+/- 10Vp-p.
Measuring Resolution	Max 30 nV—depends on voltage level.
Screen Resolution	4 digits in engineering notation.
Transmitter	200W internal transmitter. 5kW, 10kW and 15kW external transmitters also available (see separate brochure).
Output Current	1 – 2000 mA continuous, measured to high accuracy.
Output Voltage	800 Vp-p—actual electrode voltage depends on transmitted current and ground resistivity.
Input Channels	Five models available—8-, 6-, 4-, 2-, or 1-channel.
Input Gain Ranging	Automatic—always uses full dynamic range of receiver.
Input Impedance	>150 MOhm.
SP Compensation	Automatic cancellation of SP voltages during resistivity measurement. Constant and linearly varying SP cancels completely (V/I and IP measurements).
Type Of IP Measurement	Time domain chargeability (M). Six time slots measured and stored in memory.
IP Current Transmission	ON+, OFF, ON-, OFF.
IP Cycle Times	0.5, 1, 2, 4, and 8 s.
Measure Cycles	Running average of measurement displayed after each cycle. Automatic cycle stops when reading errors fall below user set limit or user set max cycles are done.
Resistivity Cycle Times	Basic measure time is 0.2, 0.4, 0.8, 1.2, 3.6, 7.2, or 14.4 s as selected by user via keyboard. Autoranging and commutation adds about 1.4 s.
Signal Processing	Continuous averaging after each complete cycle. Noise errors calculated and displayed as percentage of reading. Reading displayed as resistance (dV/I) and apparent resistivity (ohmm or ohmft). Resistivity is calculated using user-entered electrode distances.
Noise Suppression	Better than 100 dB at f >20 Hz.Better than 120 dB at power line frequencies (16 2/3, 20, 50, and 60 Hz) for measurement cycles of 1.2 s and above.
Total Accuracy	Better than 1% of reading in most cases (lab measurements). Field measurement accuracy depends on ground noise and resistivity.Instrument will calculate and display running estimate of measuring accuracy.
System Calibration	Calibration is done digitally by the microprocessor based on correction values stored in memory.
Supported Configurations	In manual mode: Resistance, Schlumberger, Wenner, dipole-dipole, pole-dipole, and pole-pole.In automatic mode: Any configuration can be programmed via command file.
Operating System	Stored in reprogrammable flash memory. Updated versions can be downloaded from our website and stored in the flash memory.
Data Storage	Full resolution reading average and error are stored along with user-entered coordinates and time of day for each measurement. Storage is effected automatically in a job-oriented file system.
Data Display	Apparent resistivity (ohmmeter), current intensity (mA), and measured voltage (mV) are displayed and stored in memory for each measurement.Data can also be displayed on an Android device in real time as bright color pseudosections, IP curves, transmitter/receiver plot, contact resistance measurements, and more.
Memory Capacity	Virtually unlimited data storage in real time on controlling Android device.The internal SuperSting memory can store more than 79,000 measurements (resistivity mode) and more than 26,000 measurements in combined resistivity/IP mode.
Data Transmission	Data can be instantaneously transferred from the Android device by email or by file transfer from the Android device USB port. RS-232C channel available to dump data from instrument to a Windows-type computer on user command.
Automatic Multi-Electrodes	The SuperSting is designed to run dipole-dipole, pole-dipole, pole-pole, gradient, Wenner, and Schlumberger surveys including roll-along surveys completely automatic with the patented Dual Mode Automatic Multi-Electrode system (U.S. Patent 6,404,203) or a passive electrode cable system. The SuperSting can run any other array by using user-programmed command files. These are ASCII files that can be created using a regular text editor. The command files are uploaded to the SuperSting RAM memory and can at any time be recalled and run as a survey.
