The origin of pantellerites and the geology of the Eburru volcanic complex, Kenya Rift, Africa

Abstract

The Eburru volcanic complex is located in the central portion of the Kenya rift. It belongs to the complex of volcanoes—Suswa, Longonot, Olkaria, Eburru, and Menengai—that form the Kenya Dome. These volcanoes are geothermal fields, and Olkaria is the site for the first geothermal power plant (1980) in the East African Rift System (EARS). On the other hand Eburru was explored in 1989, and only one of six wells drilled was productive. ^ The Eburru volcanic complex is formed of trachytes, pantellerites and pyroclastic deposits, and it is associated with a basaltic field immediately to its north, the Bad Lands or Elmenteita basaltic area. The volcanic lavas of Eburru and Bad Lands have not been geochronologically dated, although their relative ages are estimated to be between 1.2 Ma and 100 years (Clarke et al., 1990). A major faulting event has been used to differentiate the lavas into older and younger sequences. (Abstract shortened by UMI.) ^
