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
