WebBesides minerals, mineraloid solids occur in some chemical sedimentary rocks. For example, the carbonaceous material in coal is an organic mineraloid rather than a mineral. Another example, opal, is a chemical sedimentary rock that does not have a fully developed crystal lattice and therefore is a mineraloid. Sediments Webp. 2 have distinctive colors, but a majority of minerals occur in a variety of colors or are colorless. Fluorite, for example, can be purple, green, yellow, clear, or even blue. The streak is the color of a finely powered mineral – the minerals dust. The color of the streak left by some minerals is a more reliable property than their color. Keep in mind that the streak of …
