Kigoma is one of Tanzanias most remote and poor regions. Even though it has a huge geological diversity (surveyors identified gold, copper, opal, magnetite, agate, limestone and salt sites), there is very limited investment and infrastructure. Only limestone and salt mining got well off the ground.
The limestone that makes up these cave formations is known as quot;travertinequot; and is a chemical sedimentary rock. A rock known as quot;tufaquot; is a limestone formed by evaporation at a hot spring, lake shore, or other area.

Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being limesecreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil
