That which resembles a rock in firmness; a defense; a support; a refuge. "The Lord is my rock, and my fortress." (2 Sam. Xxii. 2) 4. Anything which causes a disaster or wreck resembling the wreck of a vessel upon a rock. 5. <zoology> The striped bass. See Bass.

Roche a rock] Same as Roche alum. Rock barnacle, any one of several species of wrens of the genus Salpinctes, native of the arid plains of Lower California and Mexico. Origin: OF. Roke, F. Roche; cf.

| rock oil | Rock oil, mineral oil, or natural oil, a dark brown or greenish inflammable liquid, which, at certain points, exists in the upper strata of the earth, from whence it is pumped, or forced by pressure of the gas attending it. It consists of a complex mixture of various hydrocarbons, largely of the methane series, but may vary much in appearance, composition, and properties. It is refined by distillation, and the products include kerosene, benzine, gasoline, paraffin, etc. Petroleum spirit, a volatile liquid obtained in the distillation of crude petroleum at a temperature of 170 deg Fahr, or below. The term is rather loosely applied to a considerable range of products, including benzine and ligroin. The terms petroleum ether, and naphtha, are sometimes applied to the still more volatile products, including rhigolene, gasoline, cymogene, etc. Origin: NL, fr. L. Petra a rock + oleum oil: cf. F. Petrole. Cf. Petrify, and Oil. Source: Websters Dictionary (01 Mar 1998) |
| rock shaft | <machinery> A shaft that oscillates on its journals, instead of revolving, usually carrying levers by means of which it receives and communicates reciprocating motion, as in the valve gear of some steam engines.

| rock crystal |
Quartz is the second most abundant mineral in the Earth's crust. It has a hexagonal crystal structure made of trigonal crystallized silica (silicon dioxide, SiO2), with a hardness of 7 on the Mohs scale. Density is 2.6 g/cm³. The typical shape is a six-sided prism that ends in six-sided pyramids, although these are often distorted, or so massive that only part of the shape is apparent from a mined specimen. ...
