Nuclear Tracks and Radiation Measurements (1982), 1984
Abstract Anisotropic track registration in muscovite is studied by means of a point-like 252Cf source. Impact distributions are analysed as well as distributions in azimuthal angles. It is found, by comparison with other data, that irradiation from external sources may lead to a pattern of anisotropy that differs from that of inner tracks.

IT is well known that large, well-crystallized sheets of muscovite mica are resistant to thermal decomposition at temperatures above 500° C. Hidnert and Dickson1, for example, reported that heating at 600° C for 1 h produced little or no change in the properties of a large number of different muscovite samples. Finely divided muscovite, however, begins

Experimental deformation of muscovite
Journal of Structural Geology, 1993Abstract The strength and mechanical anisotropy of muscovite have been investigated by shortening single crystals at 45°, 0° and 90° to the basal plane (001) at temperatures T from 20 to 400°C, confining pressures Pc from 10 to 400 MPa, and strain rates e from 2.5 × 10−7 to 2.3 × 10−4 s−1.

Diffusion of 40Ar in muscovite
Geochimica et Cosmochimica Acta, 2009Abstract Hydrothermal treatment of closely sized muscovite aggregates in a piston-cylinder apparatus induced 40Ar∗ loss that is revealed in 40Ar/39Ar step heating spectra. Age spectra and Arrhenius data, however, differ from that expected from a single diffusion length scale.
