Mica   Listen
noun
Mica  n.  (Min.) The name of a group of minerals characterized by highly perfect cleavage, so that they readily separate into very thin leaves, more or less elastic. They differ widely in composition, and vary in color from pale brown or yellow to green or black. The transparent forms are used in lanterns, the doors of stoves, etc., being popularly called isinglass. Formerly called also cat-silver, and glimmer. Note: The important species of the mica group are: muscovite, common or potash mica, pale brown or green, often silvery, including damourite (also called hydromica and muscovy glass); biotite, iron-magnesia mica, dark brown, green, or black; lepidomelane, iron, mica, black; phlogopite, magnesia mica, colorless, yellow, brown; lepidolite, lithia mica, rose-red, lilac. Mica (usually muscovite, also biotite) is an essential constituent of granite, gneiss, and mica slate; biotite is common in many eruptive rocks; phlogopite in crystalline limestone and serpentine.
Mica diorite (Min.), an eruptive rock allied to diorite but containing mica (biotite) instead of hornblende.
Mica powder, a kind of dynamite containing fine scales of mica.
Mica schist, Mica slate (Geol.), a schistose rock, consisting of mica and quartz with, usually, some feldspar.

... to the northeast over several craggy hills. At one place we found many exfoliating lumps of mica; we cleaved out sheets of it nearly a foot square, which Addison believed might prove valuable ...

... the limestone as being useless, and thrown aside, or in some instances, when of peculiar beauty, sold as specimens. The variety of serpentine known as marmolite, which is made up of numberless plates of the mineral packed together similar to mica, but of the green color of the serpentine picolite, or fibrous serpentine, also frequently occurs of a light grass green color, and is a very ...

... everywhere among the rosemary-bushes, while the Glow-worms light up their blue lamps to complete the revels. The delicate instrumentalist consists chiefly of a pair of large wings, thin and gleaming as strips of mica. Thanks to these dry sails, he fiddles away with an intensity capable of drowning the Toads' fugue. His performance suggests, but with more brilliancy, more tremolo in the execution, the song of the Common Black Cricket. Indeed the mistake would certainly be made by any one who ...

... rivers or torrents, even when they have no communication with the high mountains, are filled with fragments of granite and shistose mica; but the hills themselves are in general composed of clay, intermixed with various proportions of sand, mica, and gravel. This mixture contains many masses of rock, and is disposed in strata, that are either horizontal, or dip towards the north with an angle less than 25 degrees. ...

... par, but particularly the former, not only in the mouth and external appearance, but also in the anatomical structure. Upon the top of the head there is a very distinct shape of a heart, covered with a transparent substance of a brownish colour, resembling a thin lamina of mica slate, through which the brain is visible. This peculiar mark proves it to be as yet a distinct and undescribed species. Nothing is ever found visible to the naked eye in the stomach of the Vendace. They are ...

... along the coasts. In the same manner as the granite of Galicia contains tin disseminated in its mass, that of Cape Finisterre probably contains micaceous iron. In the mountains of the Upper Palatinate there are granitic rocks in which crystals of micaceous iron take the place of common mica. ...

... the girls as well as the boys were hilarious. When they shouted in the high and vaulted chambers their voices were echoed thunderously in their ears. The flaming tapers were reflected in places from many points of quartz, or mica. The floor of the cavern was quite smooth, and rose only a little. In places the walls were worn as smooth as glass. In some dim, past age the center of this island must have been a great lake, and the water had found ...

... heat by radium is in itself sufficiently remarkable, this heat is probably only a small portion of the energy radium is constantly sending into space. It is at the same time hurling off material particles which reveal their impact on a screen by luminous scintillations. Stop these by a glass or mica screen, and torrents of Roentgen rays still pour out from a few milligrams of radium salt in quantity to exhibit to a company all the phenomena of Roentgen rays, and with energy enough to produce a nasty blister on the flesh, if kept near ...

... to find, for I came down through the mountains, and as I looked from a distant shoulder of the hills for the little bay full of greenery, it was not to be seen. There was only a white town shining far off against the brown cliffs, like a flake of mica in a cleft of the rocks. Then I slept that night, full of care, on the hillside, and rising before dawn, came down in the early ...

... others formerly in use. He thinks they were brought from Borneo. (H.V. Stevens, Zeitschrift fuer Ethnologie, 1896, ht. 4, p. 181.) Bloch, who brings forward other examples of similar devices (Beitraege zur AEtiologie der Psychopathia Sexualis, pp. 56-58), considers that the Australian mica operation may thus ...

... those days the art of constructing dynamos was about as dark as air navigation is at present.... Edison also improved the armature by dividing it and the commutator into a far greater number of sections than up to that time had been the practice. He was also the first to use mica in insulating the commutator sections from ...

... ever with his eyes to earth for minerals, he finds stones specked with mica, and false diamonds, whence the height above Quebec is called Cape Diamond. It is enough. The crews spend the year loading the ships with cargo of worthless stones, and set sail in May, high of hope for wealth great as Spaniard carried from Peru. June 8 ...
