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. ❋ Thomas Mitchell (1823)
I ascended one, and found it was capped with trap rock in amygdaloidal nodules. ❋ Unknown (2003)
This hill consisted of amygdaloidal trap in nodules, the crevices being filled with crystals of sulphate of lime, and there were many round balls of ironstone, like marbles or round shot, strewed about. ❋ Unknown (2003)
It is a common product of alteration in igneous rocks, and frequently occurs as well-developed crystals in association with zeolites lining the amygdaloidal cavities of basaltic and other rocks. ❋ Various (N/A)
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. ❋ Unknown (1915)
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. ❋ Unknown (1915)
The Fountain of Saint Vulcan, anti-blepharous and amygdaloidal, was charged with such potent minerals that a single spoonful produced a diarrhoea more distressing to witness than cholera. ❋ Norman Douglas (1910)
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. ❋ James Bryce Bryce (1880)
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. ❋ Unknown (1865)
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. ❋ Unknown (1864)
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. ❋ Thomas Belt (1855)
There was no outlet, for it was a _cul-de-sac_ -- a natural court -- such as are often found among the amygdaloidal mountains of Mexico. ❋ Mayne Reid (1850)
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. ❋ Mayne Reid (1850)
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. ❋ Hugh Miller (1829)
Liasic bed occurs in an exposed front directly over it, coped by a thick bed of amygdaloidal trap. ❋ Hugh Miller (1829)
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. ❋ Hugh Miller (1829)
Among the blocks that load the beach, and render our onward progress difficult and laborious, we detect occasional fragments of an amygdaloidal basalt, charged with a white zeolite, consisting of crystals so extremely slender that the balls, with their light fibrous contents, remind us of cotton apples divested of the seeds. ❋ Hugh Miller (1829)
