Palaeogene Sandstones of the Manika Plateau, DR Congo: Sedimentology, Geochemistry, and Tectonic Implications | Chapter 4 | Chemical and Materials Sciences: Developments and Innovations Vol. 7

This study presents an analysis of Paleogene sandstones from the Manika Plateau in Kolwezi, Democratic Republic of Congo. These sandstones are classified in the “Grès polymorphes” group, which, together with the overlying “Sables ocre”, make up the Kalahari Supergroup. The sedimentological study of this sandstone was based on granulometric analysis by sieving, petrographic and morphoscopic analysis using an optical microscope and binocular loupe, and chemical analysis of major and trace elements by optical emission spectrometer (ICP-OES) and mass spectrometry respectively (ICP-MS). The results show that the sandstones are quartz arenites with a high degree of mineralogical, textural and chemical maturity. Sandstones are recycled deposits formed in an intracratonic sedimentary basin within a passive continental margin. They have been transported over long distances by fluvial processes. Initially, these sandstones were derived from intense alteration of felsic magmatic rocks, mainly tonalite-trondhjemite-granodiorite (TTG) complexes, under warm, humid paleoclimatic conditions and oxidizing environments.

Organic Manure on the Crop Yield of Corn (Monoculture in Association with Cowpea) in Ngandajika Region in Central Democratic Republic of Congo: A Comparative Analysis | Chapter 6 | Research Highlights in Agricultural Sciences Vol. 3

 The present study highlights to compare the two coprolites Tithonia diversifolia and club stool in both monoculture systems as association that's used by tropical directors inSub-Saharan Africa, particularly the DRC, with the variety of QPM. This logic includes the artistic association system, which is used by small growers and the maturity of growers inSub-Saharan Africa. still, this system faces the same limitations as the conventional system, similar as the lack of readily available organic fertiliser despite input from the most accessible agrarian patron in tropical areas. Tithonia diversifolia and stool- club organic emendations can be set up in the tropics, with the club parentage ways producing club stool that have just been developed. Both diseases may well contribute to the development of husbandry, not only because of their uproariousness in nutrients, but also their vacuity. A study was conducted in the region Gandajika by testing, both organic diseases in monoculture sludge( QPM variety) and in association with cowpea. The organic ordure can be recommended to growers in their product systems in tropical regions, especially those in the read Ngandajika region.
