Sukulu
The Sukulu is a tertiary carbonatite complex with a diameter of around four kilometers and the southernmost of a group of alkaline complexes in southeastern Uganda near the Kenyan border and belongs to the African rift valley .
location
Its name comes from the Sukulu Hills, an approximately 200 m high, ring-shaped group of hills. It is located about 4 kilometers south-southwest of the city of Tororo .
geology
The syenites surrounding the complex are not exposed and only known from drilling. The carbonatite consists mainly of coarse-grained calcite carbonatite ( Sövit ), with dolomitic and ankeritic phases occurring. In addition, tingual dikes and occasionally fenitized breccias occur. The accessory minerals mainly represented by magnetite, apatite, pyrite , pyrochlore and dark mica , subordinate to zircon , baddeleyite , barite , pyroxene , chalcopyrite , lead and gold .
Due to the morphology, residual soils up to 60 m thick have been deposited in the three valleys between the carbonatitic hill chains , in which magnetite and apatite in particular have accumulated as residual soaps in partially degradable amounts. In the North Valley in particular, these were produced by Tororo Industrial Chemicals and Fertilizers Ltd. between 1960 and 1970. (TICAF) and enriched in a flotation plant to around 40% phosphate content and sold as fertilizer. During the economic decline under the rule of Idi Amins and the subsequent civil war, production was stopped.
