The rarer stones, sphene and epidote, likewise exhibit this property markedly.
Mica, epidote, and chlorite are also present as accessories.
Magnetite is often accompanied by rocks containing garnet, epidote and hornblende.
He lets the pale little film of epidote grow right past him; stopping his own summit for it; and he never himself grows any more.
A rock composed of quartz and epidote is known as epidosite.
epidote is an abundant rock-forming mineral, but one of secondary origin.
Biotite, if present, is brown; epidote is yellow or colourless; rutile, apatite and quartz all occur with some frequency.
These are dependent upon a secondary characteristic, viz, the presence of epidote in large or small quantities.
Parallel with the micas that cause the schistosity, the growth of the quartz and epidote lenses took place.
A nearly uniform greenish compound of epidote intimately mixed with quartz, also occurs at this place.
