The epidote of this place is in general of a pale-greenish colour, but is mixed with, and sometimes appears to pass into, spots of a rich purplish-brown. The specimens resemble generally the epidote of Dauphiny and Siberia; but Mr. Levy, who has been so good as to examine them, informs me that the crystals exhibit some modifications not described either by Hauy, or by Mr. Haidinger in his paper on this mineral, and which are probably peculiar to this locality.
WATER ISLAND, on the west side of CAPE VOLTAIRE, at the south-west entrance of Port Warrender, is described (volume 1) as consisting of quartzose sandstone; as is also KATER ISLAND, in Montagu Sound. And the same rock appears to occur throughout the islands on this part of the coast. (Narrative 1.)
MONTAGU SOUND, about five-and-twenty miles south-west of ADMIRALTY GULF (Narrative 1). Greyish granular quartz; like that of the Lickey Hill, in Worcestershire. Fine-grained quartzose sandstone, of a purplish hue, resembling a rock on the banks of the Severn, near Bridgenorth. Grey and reddish sandstone; apparently composed of the debris of granite, and very nearly resembling that of Simms Island above-mentioned.
HUNTER’S RIVER, falling into YORK SOUND, on the north-east side. Somewhat coarse reddish-white sandstone; like that of the coal formation, and some varieties of millstone grit. Fine-grained, reddish-grey quartzose sandstone, having the appearance of stratification, and resembling the rocks of Cambridge Gulf.
ROE’S RIVER, at the eastern termination of York Sound (Narrative 1) runs between precipitous banks of sandstone, in nearly horizontal strata, which rise to the height of three hundred feet.
CAREENING BAY, between York Sound and Prince Regent’s River (Narrative volume 1. See the plate volume 1). Crystalline epidote, and whitish quartz, apparently from a vein. Purplish-brown epidote, with small nests or concretions of green epidote and quartz; forming a sort of amygdaloid. Conglomerate, containing angular fragments of yellowish-grey quartz-rock, in a base of compact epidote. A nearly uniform greenish compound of epidote intimately mixed with quartz, also occurs at this place. Flat lamellar chalcedony. Very fine-grained reddish-grey quartzose sandstone, with traces of a slaty structure, resembling that of York Sound, and Cambridge Gulf, was found in the north-east end of this bay; and fine-grained greenstone, on the summit of the adjacent hills.
Several of these specimens are almost identical with those of Port Warrender; from which place Careening Bay is distant about sixty miles.
BAT ISLAND (Narrative volume 1) western entrance of Careening Bay. Quartz from thin veins, with particles of an adhering rock, probably chlorite-slate. Quartz, containing disseminated hematitic iron-ore and copper pyrites. Quartz crystals, with chalcedony, from nodules in amygdaloid. Quartz with specular iron ore. Greenstone, with chalcedony and copper pyrites. A decomposed stone, probably consisting of wacke. The specimens of trap-rocks from this place are from a cavern.
