The geology of the Singida kimberlite pipes, Tanganyika
1962Fifty-four kimberlite pipes and dykes cut Precambrian granite in the Singida region of Tanganyika. The pipes range from 60 to 2500 feet in diameter, and occur in clusters and lines. The lines follow fracture zones. In addition to intrusive kimberlite, the pipes contain massive to stratified kimberlite tuff and sedimentary-tuffaceous beds.

XENOLITHS OF HORNBLENDITES FROM THE UDACHNAYA KIMBERLITE PIPE
Russian Geology and Geophysics, 1995Based 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.

Improvements in Search Techniques to Detect Kimberlite Pipes
81st EAGE Conference and Exhibition 2019, 2019Summary 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.

Eclogite clinopyroxenes from the kimberlite pipes of Yakutia
Lithos, 1968The 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 ...
