"Augite" Quotes from Famous Books
 ... bed of the river contains very minute particles of igneous rock. The slopes of the range of Comet Creek are composed of rich black soil, in some places without trees, in others openly timbered. Stones of a light coloured rock, with crystals of augite, pebbles of sandstone, of conglomerate, and of quartz, are scattered over the ground, or imbedded in the loamy beds of the water-courses. The belt of scrub at the foot of the slopes runs out in narrow strips towards the river, and these are separated by box-tree thickets, and open ...

... remain suspended in the water like a balloon in midair. Taken, then, a liquid which is heavy—the most convenient is methylene iodide, whose specific gravity is 3.3—a fragment of zircon will sink in this, and a fragment of tourmaline will float, but a fragment of the mineral augite, whose specific gravity is also 3.3, will remain ...
