ABSTRACT
From April to June, 1960, a geological team from the University of Ghent at the Lower Semliki, south of Lake Albert, sought to settle the question of existing relations between peneplains and sedimentary formations of the Albertine Rift. These are two kinds: the cartography of the glacial moraines, and a botanical treatise of the special flora of the high African mountains. The dispersion of certain species and the relationships of certain others indicate that important climate fluctuations, principally of temperature, must have extended over all the center of the African continent during recent geological times. The paleoecological interpretation of geological succession depends on paleoclimatic indices, many of which, based on the facies of formations, are illusory for many reasons. Among others: the conditions of the genesis of the recent sediments are not well known; in spite of the recent progress of pedology, genetic interpretation of paleosoils is extremely tricky, more so, at least, than has been generally believed.
