Powdering Powdering is the pulverization of the cuttings by regrinding (failure of the mud to remove cuttings from the bit), or by crushing between the drill pipe and the wall of the borehole. It can result in the disappearance of cuttings from some intervals and the erroneous logging of chalky limestone where none exists. Fusing

Mica Schist is a metamorphic gemstone showing pronounced "schistosity". This means that the stone is composed of mineral grains oriented in such a way that the stone is easily split into thin flakes or plates of Mica. This effectively gives the stone a characteristic lustre or pearlescence making it a beautiful gem to work with.

Mica is widely distributed and occurs in igneous, metamorphic and sedimentary regimes. Large crystals of mica used for various applications are typically mined from granitic pegmatites.. The largest documented single crystal of mica was found in Lacey Mine, Ontario, Canada; it measured 10 m × 4.3 m × 4.3 m (33 ft × 14 ft × 14 ft) and weighed about 330 tonnes (320 long tons; 360 short tons).
