Pascal NKURUNZIZA is Associate Professor and Teacher in the Department of Earth Sciences of the Faculty of Sciences at the University of Burundi. He is responsible for the courses of Mineralogy, Crystallography, Surface Geology and Sedimentology. He has also held political positions in the past, such as Minister of Public Works and Equipment, Minister for the Reintegration and Resettlement of Displaced Persons and Returnees (1996-2001), but has also held legislative functions such as Senator in the Senate of Transition (2001-2005). Professor Pascal NKURUNZIZA has made several publications and research related to the Earth Sciences, notably in the field of alteration, transport and sedimentation processes, geohazards but also in the sector of Integrated Water Resources Management. He is an academic resource for other Universities such as the Official University of Bukavu and the University of Ngozi where he teaches for several years the courses of Exogenous Petrology, Geology and Mineralogy of Clays and Superficial Geology. For some time, he is a Visiting Professor at the German Universities of Tuebingen and Rottenburg.


ABSTRACT

SESSION 3:  The Geology and Geomorphology of the Lake Tanganyika and the Status of Hydrocarbon Exploration


Several studies have been carried out by various researchers (Lezzar et al.1996, Tiercelin et al., 1992, Elf-Aquitaine (1983-1986), etc... with the aim of knowing the geology and geomorphology of Lake Tanganyika.


The aim of this work is to summarize some of the results obtained by these different studies so that the public can benefit from them. The latter were carried out in different periods and various methods according to the objective were used. In order to know the geomorphology of Lake Tanganyika, geophysical methods of seismic reflections were used. Using these methods, it was possible to identify different normal sequences of sedimentary deposits as well as discontinuities and asymmetries of tectonic structures which sometimes form the basis of the formation of hydrocarbons.


Thus, We are now observing a lot of research that are conducted with the aim of investigating the possibility of finding oil deposits taking into account already collected data on the geology, tectonic structure and type of sedimentation in this tectonic rift which houses the Lake Tanganyika.


Moreover, when we analyze the different discoveries of hydrocarbon deposits, whether it is methane gas or petroleum, in the sub-region, as well as the comparison of sediment types and their thicknesses in the various basins along the Albertine rift, it becomes justified to have hope that someday, these investigations will lead to positive results: the discovery of hydrocarbon deposits.


However, the exact knowledge of such deposits requires not only tremendous financial resources but also a very advanced know-how in connection with the hydrocarbon formation. In this context, it is necessary to acquire knowledge in disciplines such as geology in general but especially in geophysics, structural geology, sedimentology, hydrocarbon gitology, biology and bio-ecology, etc.


Taking into account the knowledge already accumulated on the geology and geomorphology of the rift, foreign companies are in the process of making explorations and 4 blocks of explorations have already been attributed to them. These are blocks A (793.1Km2), B (697.1Km2), C (664Km2) and D (813.4Km2).
