Copper, mercury, and iron ores, as also pure copper, ochre and sulphur, are found in the peninsula.
In the Woldeba district hermits dress in ochre-yellow cloths, while the priests of some sects wear hides dyed red.
Minerals which were not mined commercially in 1902 include asbestos, which occurs in Spartanburg and Pickens counties; fullers'-earth; graphite in Spartanburg and Greenville counties; iron ores in the north and north-west portions of the state; iron pyrites in Spartanburg and York counties; talc, bismuth, ochre, pyrites, ' galena, brown coal, malachite, phosphate of lead and barytes.
Pottery, fire, ochre and brick clays are abundant, the first two mainly in the eastern part of the state.
Other industries are brewing, printing and iron-founding, and there are ochre and iron mines in the neighbourhood.
Gault); (5) oxides of iron (staining the clay bright red when ferric oxide, red ochre; yellow when hydrous, e.g.
Yellow ochre); (6) sand or detrital silica (forming loams, arenaceous clays, argillaceous sandstones, &c.).
Yellow and red ochre mixed with grease are coarsely smeared over the bodies, grey in coarse patterns and white in fine patterns resembling tattoo marks.
These actions are of extreme importance in nature, as their continuation results in the enormous deposits of bog-iron ore, ochre, and - since Molisch has shown that the iron can be replaced by manganese in some bacteria - of manganese ores.
Ochre, or mineral paint, and mineral waters, too, are widely distributed.
The houses are neatly built of clay, coloured with red ochre, and frequently ornamented with rudely carved pillars.
Red ochre, for which there is only a limited market, is mined on Ormuz, Abu Musa and other islands in the Gulf; salt, as deposits, on Ormuz and Qishm I., and by evaporation, near Mohammerah, Fao and elsewhere on both sides of the Gulf; gypsum is widely distributed throughout the Gulf; iron, as haematite and pyrites, widely found through the Ormuz series.
Their produce has gradually decreased since the 17th century, and is now unimportant, but sulphate of copper, iron pyrites, and some gold, silver, sulphur and sulphuric acid, and red ochre are also produced.
The element is not found in the free state in nature, nor to any large extent in combination, occurring chiefly as chrome-ironstone, Cr 2 O 3 FeO, and occasionally being found as crocoisite, PbCrO 4, chrome-ochre, Cr 2 0 3, and chromegarnet, CaO Cr 2 O 3.3SiO 2, while it is also the cause of the colour in serpentine, chrome-mica and the emerald.
The flatness of faces of stone or rock (both granite and limestone) was tested by placing a true-plane trial plate, smeared with red ochre, against the dressed surface, as in modern engineer.
It often passes into an earthy form, termed soft red ore, and when mixed with more or less clay constitutes red ochre, ruddle or reddle (Ger.
Molybdenum occurs in nature chiefly as the minerals molybdenite (MoS 2) and wulfenite (PbMo04), and more rarely as molybdic ochre (Moos) and ilsemannite; it also occurs in many iron ores.
The state contains deposits of iron, gypsum, marl, phosphate, lignite, ochre, glass-sand, tripoli, fuller's earth, limestones and sandstones; and there are small gas flows in the Yazoo Delta.
They are preceded over the whole area by a much simpler form of burial marked by the practice of staining the bones with red ochre, and the presence of one or two rude pots and nothing more: yet that some were tombs of great chiefs is shown by the great size of the barrows heaped over them.
The oxide, bismuth ochre, Bi 2 O 3, and the sulphide, bismuth glance or bismuthite, are also of commercial importance.
He stood high 3 "Reddle or Red Ochre from the Forest of Dean in Gloucestershire is very little inferior to the Sort brought from the Island of Ormuz in the Persian Gulph and so much valued and used by our Painters under the name of Indian Red" (Sir John Hill, Theophrastus's History of Stones, London, 2774).
