Extract

Calcic and alkaline eruptive rocks representing many varieties have an extensive development along the northern portion of the eastern Rift Zone in the Tanganyika Territory. They are closely similar to those better known to British geologists in Kenya Colony, and in both areas have received a considerable amount of attention from petrologists.1 In Tanganyika Territory the nearest of these occurrences to the Indian Ocean hitherto known, with one exception, to be referred to later, is more than 130 miles from the coast, and the greatest development lies at 170 to about 250 miles inland.
