Abstract

The carbonate matrix of several pyroclastic tuff rings and cones in the Monduli-Arusha area of northern Tanganyika, is believed to be of volcanic carbonatitic origin. One of the pyroclastic tuff rings contains ejected blocks of ultrabasic composition which are minera-logically similar to the cognate xenoliths found in kimberlite pipes.
