The microgravity survey using Scintrex CG-5 and CG-6 involves precise measurements of small variations in the Earth’s gravitational field. These variations can help detect subsurface density anomalies, which are useful in geotechnical, hydrogeological, and exploration applications. Below are key aspects of conducting a microgravity survey with these instruments. 1. Introduction to Scintrex CG-5 & CG-6…

The resistivity method is an effective geophysical technique for detecting subsurface cavities. The SuperSting R8 is an advanced multi-channel resistivity imaging system used to map electrical resistivity variations in the subsurface, which helps identify voids, sinkholes, or other anomalies. 1. Principles of Cavity Detection Using Resistivity Cavities, voids, and air-filled spaces exhibit high resistivity because…

Limestone formations are highly susceptible to karstification, leading to the formation of voids, sinkholes, and cavities. The resistivity method is one of the most effective geophysical techniques for detecting these subsurface anomalies. This guide outlines the best practices for conducting a resistivity survey for cavity detection in limestone using SuperSting R8. 1. Why Use Resistivity…

Geolistrik adalah metode yang sangat efektif untuk eksplorasi air tanah dan akuifer, terutama di daerah perkebunan sawit yang didominasi oleh sedimen pasir. Metode ini membantu mengidentifikasi kedalaman, ketebalan, dan kualitas air tanah, serta membedakan lapisan yang mengandung air dari yang tidak. 1. Prinsip Geolistrik dalam Eksplorasi Air Tanah Air tanah mempengaruhi nilai resistivitas listrik. Umumnya:…
