Abstract
Modern data on the formation of the mineral composition, geochemical and isotope-geochemical features of sediments from large rivers in Africa (Zambezi, Nile, Congo), as well as U–Pb isotope ages of detrital zircon populations in sands, obtained during complex long-term studies by Prof. E. Garzanti (Universita’ Di Milano-Bicocca, Italy) and his colleagues are considered. Ideas about the influence of chemical weathering on the composition of both silts and sands of the named large rivers are briefly summarized. The influence of river segmentation on the composition of the transported aluminosiliciclastics is discussed. The key points of the research results presented in the overview are outlined for specialists studying ancient sedimentary sequences.
期刊介绍：
Lithology and Mineral Resources is an international peer reviewed journal that publishes articles on a wide range of problems related to the formation of sedimentary rocks and ores. Special attention is given to comparison of ancient sedimentary rock and ore formation with present-day processes. The major part of the journal is devoted to comparative analysis of sedimentary processes on the continents and in oceans, as well as the genetic aspects of the formation of sedimentary and hydrothermal–sedimentary mineral resources. The journal welcomes manuscripts from all countries in the English or Russian language.
