A dodo laying an egg makes a distinctive musical plop sound. While dodo eggs set on the ground like other dropped items, they do not appear to move and cannot be picked up by passing them. They must be specifically tapped and harvested.
As noted above, hornblende is a name used for a number of dark-colored amphibole minerals that are compositional variants with similar physical properties. These minerals can not be distinguished from one another without laboratory analysis.he mineral hornblende has very few uses. Its primary use might be as a mineral specimen. However, hornblende is the most abundant mineral in a rock known as amphibolite which has a large number of uses. It is crushed and used for highway construction and as railroad ballast. It is cut for use as dimension stone.
Chlorite and serpentine are alsosimilar but are usually a pale green color, are usually length slow, and are biaxial.Brucite may be stained to aid in rapid identification. Amphibole: (Hornblende) Distinctly colored and pleochroic, usually in shadesof green, yellow-green, blue-green, and brown. Green varieties usually have X =light yellow, light yellow-green, light blue-green; Y = green, yellow-green, gray-green; Z = dark green, dark blue-green, dark gray-green.
