Introduction: Highly refractory micro-minerals such as zircon, monazite and baddeleyite can survive and record intense shock metamorphism, and occasionally recrystallize to date impact events. Their microscale records have the potential to be used to deduce the timing and magnitude of large impacts in ex-situ solar system samples (i.e. meteorites, crystal clasts in breccias) provided we have a ...
Five soil-transmitted pathogenic fungi (Aspergillus niger) were isolated and selected to investigate the effect of Rare earth elements on their disease causing ability. The present study reveals the response of leguminous plant (Arachis hypogaea L.) to monazite soil containing Rare earth elements. A significant increase in plant biomass, total chlorophyll content and stress resistant product (p...
Perhaps the best known occurrence of an inverted metamorphic sequence is that found immediately beneath the Himalayan Main Central Thrust (MCT), generally thought to have been active during the Early Miocene. However, in situ 208Pb/ 232Th dating of monazite inclusions in garnet indicates that peak metamorphic recrystallization of the MCT footwall occurred in this portion of the central Himalaya...
This paper shows a simple way to synthesize series of Ce1-xSrxPO4 ceramic materials using acetate solutions Ce and Sr instead nitrate which were used so far. For synthesis, the preparation method was by mixing Ceand Sr(, with NaH2PO4 at room temperature, studied compositions (where x = 0, 0.1, 0.2, 0.3, 0.4, 0.5). The disintegration in monazite structures different sintering temperature ranges ...
