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.

Wide Format Ceramic Stones Based on Coal Mining Screenings | Chapter 1 | Research and Developments in Engineering Research Vol. 3

 This item presents the results of scientific research and laboratory experiment of the use of screenings from the Angren bitumen basin in the production of absorbent large-plan wall stones. In current years, pebbles from the Angren mine have been actively intentional as a raw material for absorbent ceramics. Interest in this bitumen residue as a raw material for the result of wide layout building stones has raised significantly. Energy preservation measures are more cost-effective than those that involve the growth of new energy beginnings. In light of economic reforms and unfavourable referring to practices or policies that do not negatively affect the environment conditions in the grown countries of the world, the intelligent use of fuel, raw materials, and additional material resources is increasingly main for the development of ceramic result. In this regard, the problem of gettv large-format potteries in the production of obstruction materials is a particularly crucial and unresolved question. The most significant factor moving the level of consistency is noticed with an increase in the sintering temperature and an increase in the grade of grinding of the coal hide. The moulding soil used to create wall grains has been assign attempts to change its composition. As a result, it was likely to produce a lot of heat-insulating, multi-slit obstruction stones, which is individual of the most hopeful developments in the field of strength-efficient construction.

Molecular Analysis of Rhizopus Fungal Species on Deteriorating Historical Sandstone Monuments: An Advanced Approach | Chapter 04 | New Visions in Biological Science Vol. 4

 Sandstone monuments may sustain a wide range of microorganisms that are involved in the biodeterioration process. Sandstone monuments are made up of Bryophyte and fungal consortia. Fungi are thought to be the most effective category of microorganisms in generating sandstone monument biodeterioration. When fungal units grow outside in the absence of food and water, they can initiate fungal colonisation and biodeterioration processes. When microbes are found on cultural heritage artefacts, it is not always assumed that they are changing the sandstone's physical qualities or chemical composition. Our research project objectives are to use molecular approaches such as RFLP and RAPD to isolate and recognise fungi. Eleven fungus species with dominance over the sandstone structures of the various monuments were isolated. It was discovered during the examination that Aspergillus species outnumber Rhizopus species. Microfungi produce discoloration and mechanical exfoliation of various monuments, which were investigated utilising molecular techniques for the creation of dark pigments, Hyphae penetration, and organic acid. As a result, the present state of knowledge regarding Rhizopus is summarised in this review.
