Formational types of porphyry copper deposits and their ore-magmatic systems
Autor: Igor MIGACHEV, Vadim ZVEZDOV, Olga MININA
Publikováno v: Domestic geology. :26-48
Two individual ore-formational types have been identified within the porphyry copper family: the gold-copper-porphyry and molybdenum-copper-porphyry ones. The fundamental difference between them lies in their geotectonic position that determines the

Typomorphic gold features as criteria of placer association with primary gold-silver-type sources (example from Mnogovershinnoye ore placer cluster)
Autor: Igor F. Migachev, Olga Minina, Vadim S. Zvezdov
Publikováno v: Domestic geology. :3-23
A comprehensive study of native gold from Mnogovershinnoye gold cluster ores and placers (granulometry, crystal morphology, internal structure, nature of exogenetic transformations, fineness and trace element composition) was performed to define plac

Self-channeling of spatially modulated femtosecond laser beams in the post-filamentation region
Autor: Yury Geints, Olga Minina, Alexander Zemlyanov
Publikováno v: Journal of the Optical Society of America B. 39:1549
The propagation of high-intensity femtosecond laser pulses in air under conditions of superposed spatial phase modulation is considered theoretically. The numerical simulations are carried out on the basis of the reduced form of a nonlinear Schrödin

Formation of The Scattering Phase Function in The Interaction of Ultrashort Laser Pulses with a Drop In a Nonlinear Mode
Autor: Andrey Bulygin, O I. Kuchinskaya, A. V. Petrov, Olga Minina, Pavel A. Babushkin
Publikováno v: 2020 7th International Congress on Energy Fluxes and Radiation Effects (EFRE).
The propagation of ultrashort laser pulses in the atmosphere is accompanied by nonlinear effects. The most low-threshold of them is the effect of cubic nonlinearity along with nonlinear absorption manifesting in aerosol. This effect should lead to th

Diffraction-ray tube analysis of ultrashort high-intensity laser pulse filamentation in air
Autor: Alexander A. Zemlyanov, Olga Minina, Yury E. Geints
Publikováno v: Journal of the Optical Society of America B. 36:3209
The results of theoretical simulation of femtosecond Ti:Sapphire laser pulse propagation in air in the self-focusing and filamentation regimes are presented. The self-focusing of pulsed radiation was analyzed based on the diffraction-ray tracing meth
