Improvements in Search Techniques to Detect Kimberlite Pipes

81st EAGE Conference and Exhibition 2019, 2019
Summary A review is made of traditional methods that have proven popular in aiding exploration for diamonds. Simple pattern recognition technique can be used to locate kimberlite pipes that have a magnetic response. Gravity tensor gradients have also started to be used.

XENOLITHS OF HORNBLENDITES FROM THE UDACHNAYA KIMBERLITE PIPE

Russian Geology and Geophysics, 1995
Based on study of structural characteristics of mineralogy and chemistry of hornblendite xenoliths from the Udachnaya Kimberlite Pipe, we have recognized pyroxene, pyroxene-plagioclase, monomineral, and mica varieties. The reaction relationships of amphibole with relict pyroxene suggest metasomatic nature of hornblendites.

Diamondiferous Eclogites from the Udachnaya Kimberlite Pipe, Yakutia

International Geology Review, 1994
Xenoliths from the upper mantle have undergone a wide variety of processes at varied temperatures and pressures, as recorded by mineral compositions and textures. Eclogite xenoliths in kimberlites are a unique source from which to obtain information about such processes.

The Geophysical Signature Of The Marsfontein Kimberlite Pipe

7th SAGA Biennial Technical Meeting and Exhibition, 2001
The M1 kimberlite pipe is located on the farm Marsfontein near Potgietersrus in the Northern province. With a surface area of roughly 0.5ha, this is by no means an insignificant diamond deposit. Over 1.8 million carats were recovered from the start of the project in 1998 to the end of 2000.

Eclogite clinopyroxenes from the kimberlite pipes of Yakutia

Lithos, 1968
The kimberlite pipes of Yakutia contain a number of rare xenoliths of deep seated origin (corundum eclogites, grospydites and diamond bearing eclogites). The chemistry of the clinopyroxenes from each of these rock types is distinctive. The pyroxenes of corundum eclogites and grospydites are aluminium rich, while a high Na 2 O content is characteristic ...
