The irregular and sporadic occurrence of chromite pods in podiform chromite deposits (PCD), especially in mountainous terranes with rough topography, necessitates finding innovative methods for reconnaissance and prospecting. This research combines several remote sensing methods to discriminate the highly serpentinized …
Borehole thermal methods have been applied in geothermal exploration, but have seldom been used in mineral exploration. However, this method has potential usefulness in exploration and in geoenvironmental investigations (Ovnatanov and Tamrazyan, 1970; Brown and others, 1980; Zielinski and others, 1983; Houseman and others, 1989).
It is commonly quoted that carbonate reservoirs contain some 50–60% of the world's oil and gas reserves (e.g. Roehl & Choquette 1985).Indeed, the world's largest oil field (Ghawar, Saudi Arabia) and the world's largest gas field (North Field/South Pars straddling the Qatar/Iran border) are both reservoired in carbonate rocks.
This is the fifth of a series of review papers on the subject of research and progress in geophysical exploration.

The primary Chromite composition exhibits high Cr varieties; the average Cr# of Chromite is 0.714, and have <0.3 % TiO2 content, which may reflect the crystallization of Chromite from boninitic magma.
mines are already exploiting other chromite layers within the Middle group, and these are the MG2, 3 and 4 [6]. This might be due to depreciation of high-grade chromite seams. Chromite processing involves crushing, milling to less than 1mm and further beneficiation using gravity circuits and spiral concentrators are widely used for this purpose.
The GREENPEG project, which is funded by the European Commission Horizon 2020 'Climate action, environment, resource efficiency and raw materials' programme, aims to develop multimethod exploration toolsets for the identification of European, buried, small-scale (0.01–5 million m 3) pegmatite ore deposits of the Nb–Y–F (NYF) and Li–Cs–Ta …

I. CHROMITE EXPLORATION Geophysical exploration methods could produce good results to outlining "anomalies", which in turn represent hidden ore bodies. Chromite is a high density metallic mineral and it is often associated with mafic/ultramafic rock. Due to its high density, gravity is the best approach for its investigation.

Mining professionals use ground penetrating radar for mineral exploration in igneous and metamorphic rocks, such as granitic pegmatite, to locate hydrothermal features including cavities and vugs. This 2D data set shows a large void containing emeralds in a pegmatite mine. This data was collected with a 900 MHz in contact with the rock surface.

22 3 Surface Geophysical Petroleum Exploration Methods 3.4 Seismic Exploration Survey 3.4.1 General The word "seismic" refers to vibrations of the earth, in-cluding both earthquakes and artificially created sound waves that penetrate into the earth. Sounds measured are in the frequency range of about 10–100 cycles s−1.
Along with the reflection studies of Reid and others (1980), this work suggests that seismic methods may be the best single exploration approach for podiform chromite discovered so far. The full results of seismic measurements at the Red Mountain site, and results at the other two mines and a fourth experimental location, are part of an ongoing ...
