When conducting an investigation of the subsurface a geoscientist will often locate specific borehole geophysical data for the area of study. This process of locating spatially where the geophysical logs have been conducted and what specific parameters have been run in each logging suite can often be difficult and take the investigator several hours or even days depending upon the size of the s...

the study area covers the northern part of the baft geological map (scale of 1:100 000 ). several porphyry and vein-type mineralization are reported from this area. a topic that is discussed in the mineral exploration community is the use of remote sensing and airborne geophysics for porphyry type mineralization. which one is more reliable and efficient in hydrothermal alteration mapping? airbo...

Electromagnetic exploration is a geophysical method for examining the Earth's interior through observations of natural or artificial electromagnetic field fluctuations. The method has been in practice for more than 70 years, and 40 years ago it was first applied to ocean areas. During the past few decades, there has been noticeable progress in the methods of instrumentation, data acquisition (o...

Over the last two decades, several advances have been made in the development and application of slim-hole geophysical sondes for use in groundwater, engineering, and environmental applications. This equipment is commonly used to provide qualitative (but detailed) estimates of grain size, sediment type, porosity, density, pore-water salinity, as well as bulk and shear moduli, to supplement geol...
