Great masses of iron haematite cropped up above the surfaces in these forests.
2
There is also a large rock of haematite under Mount Jellula.
3
The ridges are generally hardened sandstone, marked with madrepores, and masses of brown haematite.
4
And something called haematite-haveyou ever heard of haematite?'
5
Another technique is to hold a piece of haematite, a stone formed from iron oxide.
6
These are, cornelian, rock-crystal, chalcedony, onyx, jasper, quartz, serpentine, sienite, haematite, green felspar, pyrites, loadstone, and amazon-stone.
7
We now come to large masses of haematite, which is often ferruginous: there is conglomerate too, many quartz pebbles being intermixed.
8
The steep banks beyond the river consisted of clay-slate having under it a conglomerate containing fragments of quartz cemented by compact haematite.
9
Yellow haematite is very abundant, but the other rocks scarcely appear in the distance; we have mountains both on the east and west.
10
Holly, there isn't a force on Earth or under it powerful enough to stop a hundred million tonnes of molten haematite in freefall.
11
But now, laser drilling has revealed a deep orebody of haematite, iron ore, on the bottom edge of the crust, right here in Sicily.
12
Haematite has a natural grounding quality and will have some effect all by itself.
13
It chiefly occurs as oxide, as in magnetite, hæmatite, and in the brown iron ores and ochres.
14
Upon these fuliginous and amethystine crystals are many sphericles or hemispheres of red compact iron-ore, like haematites.
15
Chalybite and the hydrated oxides dissolve very readily in hydrochloric acid; hæmatite and magnetite dissolve with rather more difficulty.
16
Yellow hæmatite, which bears not the smallest resemblance either in colour or weight to the metal, is employed near Kolobeng for the production of iron.
