  • The coastal heavy mineral sand deposits of Africa

    The trailing margin of the stable African continent is the depositional environment of several heavy mineral placer deposits of which seven have developed Sedimentary rock Sandstones Britannica,One of the clues to origin is the overall shape of the entire sand deposit. Inland desert sands today cover vast areas as a uniform blanket; some ancient sandstones in beds a few hundred metres thick but 1,600 kilometres or more in lateral extent, such as the Nubian Sandstone of North Africa,of Mesozoic age (about 245 to 66.4 million yearsSedimentary Rocks National Geographic Society,For example, as a lake dries up over many thousands of years, it leaves behind mineral deposits; this is what happened in California’s Death Valley. Finally, lithification is the process by which
