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. ❋ Unknown (2004)
Pumice and trachyte are the most common rocks around this mountain, and these are augitic or porphyroid. ❋ James Orton (1853)
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. ❋ Charles Darwin (1845)
The molten trap broke through at various times, and presenting various appearances, but in nearly the same centre; here existing as an augitic rock, there as a syenite, yonder as a basalt or amygdaloid. ❋ Hugh Miller (1829)
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. ❋ Hugh Miller (1829)
The bones were dug up by Mr. Walter Mantell from a bed of marly sand, containing magnetic iron, crystals of hornblende and augite, and the detritus of augitic rocks and earthy volcanic tuff. ❋ Alexander Von Humboldt (1814)
Jasper, which, * as I have already remarked, is a production formed by the volcanic action of augitic porphyry, could only be obtained in small quantities by the ancients, while another material, very generally and efficiently used by them in the arts, was granular or saccharoidal marble, which is likewise to be regarded solely as a sedimentary stratum altered by terrestrial heat and by proximity with erupted rocks. ❋ Alexander Von Humboldt (1814)
The character of rocks, as we have already remarked is so independent of geographical relations of space, * that the geologist recognizes with surprise, alike to the north or the south of the equator, in the remotest and most dissimilar zones, the familiar aspect, and the repetition of even the most minute characteristics in the periodic stratification of the silurian strata, and in the effects of contact with augitic masses of eruption. ❋ Alexander Von Humboldt (1814)
The diamonds that occur furthest to the north, as those discovered in 1829 at 58 degrees lat., on the European slope of the Uralian Mountains, bear a geognostic relation to the black carboniferous dolomite of Adolffskoi* and to augitic porphyry, although more accurate observations are required in order fully to elucidate this subject. ❋ Alexander Von Humboldt (1814)

The thickness of the vegetation on the sides of its crater-like basin renders it difficult to discover the nature of the subjacent rock, but it is probably composed of black cellular augitic lava. ❋ Alexander Von Humboldt (1814)
'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. ❋ Alexander Von Humboldt (1814)

The cavern we had come to examine we found to be a noble arched opening in a dingy-colored precipice of augitic trap, -- a cave roomy and lofty as the nave of a cathedral, and ever resounding to the dash of the sea; but though it could have amply accommodated a congregation of at least five hundred, we found the way far too long and difficult for at least the weak and the elderly, and in some places inaccessible at full flood; and so we at once decided against the accommodation which it offered. ❋ Hugh Miller (1829)
