Kimberlites

, 1986
This is a book about the petrology of kimberlites. It is not about upper mantle xenoliths, diamonds, or prospecting for kimberlites. The object of the book is to provide a comprehensive survey and critique of the advances which have been made in ...

Indian kimberlites and the genesis of kimberlites

Chemical Geology, 1984
Abstract Late Proterozoic kimberlites occur in both southern and central India. They are similar in petrography and geochemistry to the kimberlites of southern Africa and Yakutia, U.S.S.R. These rocks contain low-CaO forsteritic olivines (Fo92), abundant phlogopites, magnesian ilmenites, aluminous—magnesian chromites, chrome-pyrope garnets surrounded

Compositional classification of ?kimberlitic? and ?non-kimberlitic? ilmenite

Lithos, 2004
Abstract Ilmenite is one of the common kimberlitic indicator minerals recovered during diamond exploration, and its distinction from non-kimberlitic rock types is important. This is particularly true for regions where these minerals are present in relatively low abundance, and they are the dominant kimberlitic indicator mineral recovered.

Kimberlite and kimberlitic intrusives of southeastern Australia

Mineralogical Magazine, 1980
SummaryFifteen widely separated occurrences of kimberlite and kimberlitic rocks are now known in south-eastern Australia. Those that have been satisfactorily dated isotopically give ages ranging from Permian to Late Jurassic. One occurrence exhibits an intimate spatial association with carbonatite.
