  1. Geographical Methods of Soil Exploration i. Electrical resistivity method This method is based on the measurement and recording of changes in the mean resistivity or apparent specific resistance of various soils. The test is done by driving four metal spikes to act as electrodes into the ground along a straight line at equal distances. This is shown in the figure. Direct voltage is applied between the two outer potentiometer electrodes and then mean for the potential drop between the inner.
  2. Selection of the appropriate exploration methods must be dictated by the characteristics of the targeted model, its geologic setting, and the surficial environment.

Graphite exploration methods G raphite exploration follows a similar path to other minerals, often from discovery of an outcrop, which is then explored by methods such as ield mapping, trenching, geophysics, drilling, assaying of the graphite content and mineralogical and metallurgical testing. Data generated in this way, if successful, can lead to the estimation of a mineral resource. At the.

Seismic Geophysical Survey • The seismic methods are the most widely used of all geophysical methods used in petroleum exploration. • Seismic methods measure seismic velocity of rock layers to detect both lateral and depth variations and the objective is to determine the lithology and geometry of the layers. • A seismic wave can be thought of as shock wave (elastic wave) or vibration. The following points highlight the two main geophysical methods of soil exploration. The methods are: 1. Seismic-Refraction Method 2. Electrical Resistivity Method. 1. Seismic-Refraction Method: The seismic-refraction method is based on the principle that elastic shock waves travel at different velocities in different materials. Shock waves are generated at a point on the ground surface, using a sledge hammer. These waves travel deep into the ground and get refracted at the interface of two.

  1. So far as geophysical methods of subsoil exploration are concerned, there can be no doubt about their desirability and merits, because they are extremely cheap: they are even cheaper than geologists. They have only one disadvantage, and that is we never know in advance whether they are going to work or not! During my professional career, I have been intimately connected with seven geophysical.

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital. Besides, metal ores can be magnetic as well as electrically.
