... A slight slope of the spectrum curves and slight Eu-anomaly are typical for them. ... The TR spectrum of the same type is indicative of similar genesis of the lamproites from various massifs of the Aldan Shield. ...
... The data of the microprobe, chemical and physical analysis show that this mineral is a pickeringite – sulfates of Fe and Mg (Fe,Mg)Al2(SO4)4ћ22 H2O. For diagnostics of a mineral we used Infra-red spectrum methodic and X-Ray powder diffraction spectrum. ...
... Since the indication from the studies of the spectrum of heterogeneity is that the spectrum is red, we might be able to determine quite accurately the long wavelength field without being aliased by the presence of the relatively weak, high wavenumber ...
