Rocks of augitic trap are found in various positions on it; the general strike is north and south; but when the gneiss was first seen, near to the basalt of the falls, it was easterly and westerly, and the dip toward the north, as if the eruptive force of the basalt had placed it in that position.    From Wordnik.com.  [Missionary Travels and Researches in South Africa] Reference

'Euphotide' and serpentine, containing sometimes crystald of augite and uralite instead of diallage, are thus nearly allied to another more frequent, and I might almost say, more 'energetic' eruptive rock -- augitic porphyry.    From Wordnik.com.  [COSMOS: A Sketch of the Physical Description of the Universe, Vol. 1] Reference

The sandstone rests on lava, is covered by a great bed apparently about 1,000 feet thick of black augitic lava, and over this there are at least 5 grand alternations of such rocks and aqueous sedimentary deposits, amounting in thickness to several thousand feet.    From Wordnik.com.  [More Letters of Charles Darwin — Volume 1] Reference

It forms the opening of a dreary moorland valley, bounded on one of its sides, to the mouth of the loch, by a homely ridge of Old Red Sandstone, and on the other by a line of dark augitic hills, that attain, at the distance of about a mile from the sea, an elevation of two thousand feet.    From Wordnik.com.  [The Cruise of the Betsey or, A Summer Ramble Among the Fossiliferous Deposits of the Hebrides.

(diorite, augitic porphyry, basalt, and the lava of AEtna) yield different products, according to the difference of the pressure under which they have been fused, and the length of time occupied during their cooling; thus, where the cooling was rapid, they form a black glass, having a homogeneous fracture, and where the cooling was slow, a stony mass of granular crystalline structure.    From Wordnik.com.  [COSMOS: A Sketch of the Physical Description of the Universe, Vol. 1] Reference
