magnetic survey is nowadays the most efficient non-destructive geophysical method. this technique puts emphasis on the measurement of anomalies of the earth’s magnetic field, caused by the presence of archaeological remains in the ground. magnetic survey is one of the oldest geophysical methods for airborne and land use. that is why there is a large volume of data that could be used for geologi...

The main purpose of geometallurgy is to develop a model to predict the variability in the mineral processing performance within the ore body. Geometallurgical tests used for developing such a model need to be fast, practical and inexpensive and include as an input data relevant and measureable geological parameters like elemental grades, mineral grades and grain size. Important in each geometal...

evaluation of the geochemistry and hydrochemical quality of bam salt dome located in southern iran, was conducted in this study. two composite samples from salt units were collected and analysed by xrd and xrf to determine their mineral and elemental compositions. water samples were also collected from the only spring in the area and analysed for major anions, cations and some toxic elements. t...

Human beings are facing a global mineral resource crisis. The earth's finite supply of minerals İs being used by a population that is growing faster than at any time in history. To make matters worse, mineral consumption İs growing even faster man the population. Although we need more minerals to supply society, we are becoming increasingly aware that their production and use pollute the planet...

Extracting and synthesizing information from existing and massive amounts of geology spatial data sets is of great scientific significance and has considerable value in its applications. To make mineral exploration less expensive, more efficient, and more accurate, it is important to move beyond traditional concepts and establish a rapid, efficient, and intelligent method of predicting the exis...

Variation in the mineral composition of rocks results in a change of their spectral response capable of being studied by imaging spectroscopy. This paper proposes the use of a low-cost handy sensor, a calibrated visible-very near infrared (VIS-VNIR) multispectral camera for the recognition of different geological formations. The spectral data was recorded by a Tetracam Mini-MCA-6 camera mounted...

Abstract The use of copper isotopes related to ore deposit location and genesis has greatly expanded over the past twenty years. isotope values in ores, rocks, soils, water range greater than 10‰ provide ample isotopic variation identify interpret complex geological process. From an exploration standpoint, waters, sulfides weathered rocks vector mineralization at depth. Ground surface waters di...
