Geophysical methods have been important in the search for gold in the Witwatersrand Basin of South Africa (magnetic, gravity and even seismic reflection methods), various areas of Canada (e.g. the Abitibi greenstone belt; magnetic, EM and IP surveys), and to a smaller extent in Australia (e.g. Tennants Creek, NT and Water Tank …
Magnesium frequently substitutes for iron in chromite. A solid solution series exists between the mineral chromite (FeCr 2 O 4) and the isomorphous mineral magnesiochromite (MgCr 2 O 4).Intermediate specimens can be rich in iron ((Fe,Mg)Cr 2 O 4) or magnesium ((Mg,Fe)Cr 2 O 4).For convenience in communication, these minerals …

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 chemical composition of the chromite tailings sample is shown in Table 1. Table 1 shows that the sample had a chromite content of 20.03% with silica as the major gangue measured at 33.50%. The iron oxide content assayed at 17.94%. The chromite content corroborates the research that was conducted by [4] which indicated that there is sufficient
2.1. Characterisation. Chromite sample was obtained from the western limb of the BIC along the Middle group seam. The samples were from MG1, MG2, MG3 and MG4. Particle size distribution on the as received samples were analysed using laboratory sieve screens. 1kg from each sample was pulverised to 80% -75μm in preparation for chemical and ...
In Orissa, India, chromite deposits occur in a NE-SW trending belt as discontinuous pods associated with tectonically deformed and metamorphosed ultramafic rocks. Geological mapping and detailed geophysical survey (including gravity, magnetic, electrical, and electromagnetic methods) for exploring chromite were conducted in a area at …

ONTARIO — Toronto-based Noront Resources is pleased with the latest high-grade assays from its Blackbird chromite deposits in the Ring of Fire. Fourteen diamond drill holes encountered massive chromite up to 32.2 metres thick and averaging 36.96% Cr 2 O 3. The highest assays were in the 40% range, but over much shorter …
This is the fifth of a series of review papers on the subject of research and progress in geophysical exploration. In the three years since the last presentation of this nature, the most salient trend in geophysical exploration has been one toward full utilization of the available data. Modern data‐processing equipment and techniques of analysis are …
