Use of gamma-ray spectrometry for identifying weakly magnetic diamondiferous kimberlites [PDF]

, 2016
Diamondiferous kimberlites are the most important source of bedrock diamond deposits. The goal of the study is to analyze the use of gamma-ray spectrometry techniques to explore weakly magnetic diamondiferous kimberlites.

Kimberlitic olivine

, 2009
Kimberlite hosts two populations of olivine that are distinguished on the basis of grain size and morphology; the populations are commonly described genetically as xenocrysts and phenocrysts. Recent studies of zoning patterns in kimberlitic olivine phenocrysts have cast doubt on the actual origins of the smaller olivine crystals. Here, we elucidate the

To assess the value of satellite photographs in resource evaluation on a national scale [PDF]

The author has identified the following significant results. The limit of resolution on ERTS imagery is normally acknowledged to be about 60 miles although very long features such as roads and railways which are often less than 10 miles long are easily ...
