Abstract/Notes | In almost every collection of minerals there may be found specimens of the curious little glassy balls, which, from the locality of their occurrence—the great Marekanka, near Okhotsk in Siberia—have received the name of Marekanile. These glassy balls are more or less perfectly rounded in form, they vary in their colour, through different shades of smoke-grey to orange-brown, while in size they range from the dimensions of a pea to those of a walnut. Most mineralogical treatises still continue to recognize Marekanite as a mineral, and class it either as a variety of Obsidian or of Pearlstone.While totally disallowing the claim of Marekanite to rank as a mineral-species or even variety—the petrographer recognizes in this substance a type of rock, which proves to be by no means devoid of interest, when its properties are carefully studied, nor destitute of suggestiveness, when its mode of occurrence is thoughtfully considered. |
