The part of the western shore where the land is highest shelters a small bay which might be made a tolerable harbour by means of two piers or quays erected on reefs of a kind of rock apparently very favourable for the purpose, namely amygdaloidal trap in rounded boulders.    From Wordnik.com.  [Three Expeditions into the Interior of Eastern Australia, Volume 2] Reference

The summit of Machacha is composed of a dark igneous rock, apparently a sort of amygdaloidal trap, with white and greenish calcareous crystals scattered through it.    From Wordnik.com.  [Impressions of South Africa] Reference

On some of the ranges we crossed, the rocks were amygdaloidal, containing nests of a white zeolite, the fractured planes of which glittered like gems on the pathway.    From Wordnik.com.  [The Naturalist in Nicaragua] Reference

It was one of those mountain torrents common in Mexico -- spots of still water alternating with cascades, that dash, and foam over shapeless masses of amygdaloidal basalt.    From Wordnik.com.  [The Rifle Rangers] Reference

Both have their edges much rounded, as if, ere their deposition in the conglomerate, they had been long exposed to the wear of the sea; and both are composed of an earthy amygdaloidal trap.    From Wordnik.com.  [The Cruise of the Betsey or, A Summer Ramble Among the Fossiliferous Deposits of the Hebrides.

The openings in rocks consist of joints and many other fractures, small spaces between the grains of rocks (pore space), and amygdaloidal and other openings characteristic of surface volcanic rocks.    From Wordnik.com.  [The Economic Aspect of Geology] Reference

The ore bodies have the form of long sheets parallel to the bedding, the copper and associated minerals filling amygdaloidal openings and small fissures in the flows, and replacing conglomeratic sediments which lie between the flows.    From Wordnik.com.  [The Economic Aspect of Geology] Reference

They occur in the amygdaloidal trap of which the upper part of the hill is mainly composed, in great numbers, and occasionally in bulky masses; but it is rare to find other than small specimens that would be recognized as of value by the lapidary.    From Wordnik.com.  [The Cruise of the Betsey or, A Summer Ramble Among the Fossiliferous Deposits of the Hebrides.

The rocks in its bed are limestone, but a great bluff cliff of sandy conglomerate (strike east-south-east and dip south-south-west 70 degrees), several hundred feet high, rises on the east bank close above the village, above which occurs amygdaloidal basalt.    From Wordnik.com.  [Himalayan Journals — Complete] Reference

A soft shelly limestone, most probably of recent origin though slightly resembling some of the oolites of England, occurs extensively on the southern coast between Cape Northumberland and Portland bay where it forms the only rock with the exception of amygdaloidal trap.    From Wordnik.com.  [Three Expeditions into the Interior of Eastern Australia, Volume 2] Reference

They are generally trap-rock, embracing the varieties of gray, porphyritic, hornblendic, sienitic, and amygdaloidal trap, and appear to have had no labor expended upon them except the chiseling of a groove around the middle for the purpose of attaching a withe to serve as a handle.    From Wordnik.com.  [Ancient Mining on the Shores of Lake Superior] Reference

The groups of heliotropes clustered each around its bulky centrical mass seem to show that the principle of molecular attraction may be operative in very dense mediæ, -- in a hard amygdaloidal trap even; and it seems not improbable, that to this law, which draws atom to its kindred atom, as clansmen of old used to speed at the mustering signal to their gathering place, the various chemistry of the vesicles may owe its variety.    From Wordnik.com.  [The Cruise of the Betsey or, A Summer Ramble Among the Fossiliferous Deposits of the Hebrides.

Equally striking is the fact that I, though now only sixty-seven years old, heard the Professor, in a field lecture at Salisbury Craigs, discoursing on a trapdyke, with amygdaloidal margins and the strata indurated on each side, with volcanic rocks all around us, say that it was a fissure filled with sediment from above, adding with a sneer that there were men who maintained that it had been injected from beneath in a molten condition.    From Wordnik.com.  [The Autobiography of Charles Darwin] Reference
