Total Count Radiation Intensity Contours 27 SE

Equivalent Uranium Concentrations 34 SE

Flight Path Location Map 51 2

Part of an airborne gephysical survey carried flown between December 1981 and February 1982. Data was collected for the Kerio valley and North East Kenya. A selection of maps were produced for each area includinga survey index map: a band pass filter magnetic field, equivalent thorium, potassium concentration contours, flight path and location maps, magnetic, radiometric interpretation, residual magnetic field contours, secondary residual magnetic field contours and profiles and target maps.

Geological mapping (1984) was carried out as part of the Samburu Marsabit Geological Mapping and Mineral Exploration Prokect, a joint Kenyan - British Overseas Development Administration Technical Co-operation Project, staffed by the Kenyan Mines and Geological Department and the Brtish Geological Survey (formerly the Institute of Geological Science) of Natural Environment Research Council. Series of 1: 250 000 scale geological maps captured in two phases. The maps cover central (phase 1) and northern Kenya (phase 2). The maps align with the 1: 500 000 scale map for the Northern Turkana area.
