Meanwhile I was occupying myself in classifying my mineralogical
, botanical, and zoological riches, when the accident happened to the Scotia.
The frequent and great changes in the mineralogical composition of consecutive formations, generally implying great changes in the geography of the surrounding lands, whence the sediment has been derived, accords with the belief of vast intervals of time having elapsed between each formation.
When we see, as is so often the case, a formation composed of beds of different mineralogical composition, we may reasonably suspect that the process of deposition has been much interrupted, as a change in the currents of the sea and a supply of sediment of a different nature will generally have been due to geographical changes requiring much time.
constitution is not simple; in some parts the rock is of a cherty, in others of a felspathic nature, including thin veins of serpentine.
They had a little conchological cabinet, and a little metallurgical cabinet, and a little mineralogical
cabinet; and the specimens were all arranged and labelled, and the bits of stone and ore looked as though they might have been broken from the parent substances by those tremendously hard instruments their own names; and, to paraphrase the idle legend of Peter Piper, who had never found his way into their nursery, If the greedy little Gradgrinds grasped at more than this, what was it for good gracious goodness' sake, that the greedy little Gradgrinds grasped it!
Raw minerals chemical and mineralogical
compositions vary significantly.

Despite the unimaginable energy produced during large impacts on the Moon, those impacts may not wipe the mineralogical
slate clean, the study suggested.
Sampling will also include recovery of a suite of samples for mineralogical
evaluation and two samples for metallurgical testing.
studies have commenced on selected REO mineralised samples as a first step prior to metallurgical test work.
After its identification, the manganese silicide became mineral number 4,325, according to the International Mineralogical
Association, which christened it Brownleeite after Donald E.
