Simplified model taking into account two parallel methods of methane gas formation in Lake Kivu ((K. Tietze, 1974 - 75).

K. Tietze's figure presents a model of the origins of methane gas.

The formation of Kivu's methane seems to be the result of two simultaneous actions :
The first due to the fermentation of biogenic sediments
The second due to the reduction in magmatic CO2 by bacteria

Our experiments in 2003-2004 indicate that the biogenic process is by far the most important
