Minerogenesis Of Volcanic Caves Of Kenya, Paolo Forti, Ermanno Galli, Antonio Rossi
Minerogenesis Of Volcanic Caves Of Kenya, Paolo Forti, Ermanno Galli, Antonio Rossi
International Journal of Speleology
Kenya is one of the few countries in which karst cavities are scarce with respect to volcanic ones, which are widespread throughout the whole country. The great variability in lava composition allowed the evolution of very different cavities, some of which are amongst the largest lava tubes of the world. As normal for such a kind of cave, the hosted speleothems and cave minerals are scarce but important from the minerogenetic point of view. Anyway up to present no specific mineralogical research have been carried out therein. During the 8th International Symposium on Volcanospeleology, held in Nairobi in February 1998, …
Guano Mining In Kenyan Lava Tunnel Caves, Jim W. Simons
Guano Mining In Kenyan Lava Tunnel Caves, Jim W. Simons
International Journal of Speleology
Commercial mining of bat guano for agricultural fertilizer only became possible in Kenya through discovery of major deposits in the lava tunnel caves of Mt. Suswa and the North Chyulu Hills in the early 1960’s. This paper provides historical information leading up to the guano mining, describes the cave deposits, outlines the mining under-takings, and provides information on the guano producing bats and insect faunas. The results of guano analyses, details of the tonnages extracted and sold to recipients between 1966 to 1984, and some benefits which resulted from its use on crops are given. A brief outline of attempts …
Overview Of The 8th International Symposium On Vulcanospeleology, William R. Halliday
Overview Of The 8th International Symposium On Vulcanospeleology, William R. Halliday
International Journal of Speleology
In February 1998 the 8h International Symposium on Vulcanospeleology was hosted by CEGEA (Cave Exploration Group of East Africa) in Nairobi, Kenya: it was attended by 16 scientists coming from 4 continents. Pre- and Post- Symposium excursions allowed the participants to have an overview on the most important and famous volcanic cave of that area.
The Cave Exploration Group Of East Africa And Volcanic Caves In Kenya, Michael Declan Kennedy
The Cave Exploration Group Of East Africa And Volcanic Caves In Kenya, Michael Declan Kennedy
International Journal of Speleology
This paper looks at the history of the Cave Exploration Group of East Africa with special reference to the exploration of volcanic caves. It demonstrates that the group has concentrated on two main areas, the Chyulu HiIls and Mt. Suswa, although other areas have also been studied. The Cave Exploration Group of East Africa has had to cope with various problems. The most important of which are related to the socio-economic conditions of a developing country. These problems have not prevented the group from making a valuable contribution to vulcanospeleology.
Lave Caves Of Kilimanjaro. Mawenzi Lava Tubes, Clive Ward
Lave Caves Of Kilimanjaro. Mawenzi Lava Tubes, Clive Ward
International Journal of Speleology
This is the first short report on the exploration of lava tubes in the upper part of Kilimanjaro. The area seems to be extremely interesting from vulcanospeleological point of view.
Tectonic Caves Of Solai In The Kenyan Rift Valley, Robert A. Davis
Tectonic Caves Of Solai In The Kenyan Rift Valley, Robert A. Davis
International Journal of Speleology
Tectonic caves at Solai, Kenya, were explored in 1970. These lie in a complex geological area of the Great Rift Valley in columnar-faulted ignimbrite. Fissures are presumed to have been widened by later tectonic activity -e.g. the major earthquake of January, 1928. The caves and exploration are briefly described. Questions of formation, drainage and possibilities of steam reservoirs are discussed.
