Meanwhile I was occupying myself in classifying my mineralogical
, botanical, and zoological riches, when the accident happened to the Scotia.
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!
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.
The team examined more than 200 Cambrian rock samples using powder X-ray diffraction analysis to determine their mineralogical
composition, comparing rocks with Burgess Shale-type fossils with those with only fossilised shells and bones.
These samples were studied by optical microscopy and X-ray diffraction for petrographic and mineralogical
characterization and for understanding the manufacturing process/ technique.

In this paper, we systematically utilized X-ray diffraction (XRD), scanning electron microscope and energy dispersive spectrometer (SEM-EDS), and electron microprobe analyzer (EPMA), and carried out detailed mineralogical
and geochemical investigations on the Salento-type bauxite in Guigang, Western Guangxi.
