...H. W. Fairbairn Abstract X -ray examination of oriented thin plates of some fine grained foliated rocks (slate and shale) shows the following: (1) A definite relation exists between the angular spread of the reflections from the oriented platy minerals and the cleavability of the rock. The smaller...

...M. D. Shappell Abstract Mineral cleavage can be resolved into two components: cleavability and optical effect. The electrical theory of matter in the solid state leads to a quantitative expression for the cleavability of ionic minerals C { h k l } = A ( h k l ) Σ i n i s i cos ⁡ θ i . Approximate...

..., but such applications require precise knowledge of the dielectric behavior of the clay. The purpose of the present study was to use Terahertz time-domain spectroscopy (THz-TDS) to determine the dielectric properties of certain cleavable layered clay minerals, including muscovite, vermiculite, phlogopite, and biotite...

... preparation using dyes. Oil-inclusion artifacts are particularly likely in soft, easily cleavable and oil-wetting minerals, including evaporites and carbonates, which are common components of petroleum reservoirs around the world. Also pseudo-inclusions could form in hard minerals and have aqueous...

.... This technique produces a sphere whose surface is entirely covered with minute cleavage steps. By employing optical light figure techniques, the planes which cleave can be identified and their relative degree of cleavability ascertained. The essence of this method is that every plane which is part...

..., and vauquelinite in the oxidized zone of galena-bearing veins. Analysis gives PbO 80.88, CrO 3 18.08; total 98.96, corresponding to Pb 2 O(CrO 4 ). The mineral is dark, cochineal red with a yellowish-orange streak; H = 2 1 2 ; p = 7.01 (meas.) 7.075 (calc.). It occurs in anhedral cleavable translucent masses. Good...

.... The principal occurrence of the sphalerite is as cleavable, red-brown masses, with calcite, filling hollows in a breccia of stromatoporoid fragments, the so-called ‘horse-bone’ conglomerate. It more rarely occurs in developed crystals in the reef itself. Several well developed crystals are in the R oot...

..., but a large angle with those of . . . * Schist and the adjectives derived from it are used in literature in somewhat variable senses. As I use it, schist denotes cleavable rooks which are allied to slates, but in which the cleavage surfaces are not all sensibly parallel to one another as they are in true...
