Geological and mineralogical research were conducted by the scanning probe microscopy and showed that in plagioclase pegmatites of North Baikal muscovite province the average thickness of the peristerites increases from early graphic zones to late trochlear zones and pegmatoid zones of pegmatite veins. The thickness reaches a maximum in the pegmatites of pegmatoid structure which contain large-crystalline muscovite. This regularity can be used for development mineralogical criteria for evaluation of pegmatite veins productivity at the large size muscovite source.
Physico-mathematical modeling has shown that color of iridescent depends on spacing of peristerite lattice. The more spacing lattice, the color of iridescent is higher. The phenomenon of iridescent in plagioclases has an interferential nature. We can select two genetic types of peristerites: peristerites of decomposition and segregation peristerites. Segregation peristerites are formed from postcrystallizational consolidation of peristerites of decomposition. The form of segregation pertisrerites is one of the reasons of polychromatic iridescent genesis in plagioclases.
Spacing of lattice for non-iridescent labradorite, blue-iridescent labradorite, green-iridescent labradorite and red-iridescent labradorite were determined with scanning probe electron microscope. Lattice spacing increases the dynamical trend for different kinds of labradorite, line non-iridescent labradorite (107,5 ± 10 nm), blue-iridescent labradorite (150 ± 10 nm), green-iridescent labradorite (196 ± 10 nm), red-iridescent (231 ± 10 nm). This trend let is state iridescent of these samples to be caused by interference of secondary order.
The small-angle X-ray scattering method was used to study samples of iridescent and noniridescent labradorites, albite and quartz. An X-ray unit fitted with a U-shaped Kratky collimator was used in the research at the wavelength of 1,51 Å. 0,1-0,2 mm thick labradorite plates and powdered minerals were used as the samples; the plates were cut across the crystallographic axis. Anisotropic scattering has been found in the plates of iridescent labradorite for the first time in the history. This scattering is probably connected with structural defects in iridescent crystals, whose typical dimensions are 50-150 nm. The curves of small-angle X-ray scattering obtained for iridescent labradorite and albite in the «scattering intensity» – «inverse space vector module» coordinates show expressed rectilinear dependence on the log-log scale. The fractal parameter D of these curves equals 2. This proves that the investigated plagioclase powder particles are characterized with flat surface within a wide range of dimensions from 10 to 150 nm. Similar scattering characteristic were received when investigating the quartz powder. It may be preliminary hypothesized that these features of X-ray scattering do not depend on cleavage characteristics.
Powders of irizing and non-irizing plagioclases (labrador and albite) were studied using a small-angle X-ray camera. The obtained curves of X-ray small-angle scattering in the coordinates "scattering intensity" - "backspace vector modulus" on a double logarithmic scale reveal a pronounced rectilinear dependence. The fractal dimensionality for these curves is D=2. This indicates that the particles of the studied plagioclase powders have a flat surface in a wide range of sizes from 10 to 150nm. It is assumed that during mineral grinding, fractures occur predominantly along certain planes. A similar scattering pattern is observed on quartz powders: a rectilinear dependence and fractal dimension D=2 are obtained. It is assumed that this peculiarity of X-ray scattering is not related to the property of mineral cleavage.
Irizing and non-irizing labrador have been studied by small-angle X-ray scattering for a wavelength of 1.51angstrom (Cu-alpha). Plates of 0.1-0.2 mm thickness cut perpendicular to the c crystallographic axis were investigated. For the experiment, an X-ray setup with a U-shaped Kratky collimator was used. Two types of scattering were detected for the first time: anisotropic and isotropic. Anisotropic scattering is characteristic only for irizing labradors. It is observed at angles of 1-5 mrad and decreases with increasing scattering angle. The isotropic scattering has a maximum at an angle of 8 mrad, the position of which does not depend on the irization of the sample. Anisotropic scattering is presumably associated with defects in the structure of irizing crystals, characteristic sizes of which are 500-1500 angstroms. Isotropic scattering is apparently determined by structural elements with linear dimensions of 150-180 Å.
An attempt is made to consider the problem of spiritual freedom through a particular symbol - edged weapons. Information is given about the main schools of the blade, internal training of a warrior. As one of the modern manifestations of the art of the blade the film "Crouching tiger, lurking dragon" is analyzed. Its main characters show the difference between a true master, who has learned harmony, and a fighter who did not devote enough time to internal training. The philosophical conclusions of the Wudang school can still facilitate some decisive choices for man today. The eternal truths help us to find peace within ourselves and to reconcile with the world around us.
