Anomalous Thermal Expansion of Muscovite Mica Implanted with Noble Gases

, 1992
Natural phlogopite micas may contain occluded water which gives rise to anomalous reversible thermal expansion behavior at high temperatures. Expansions as much as 200% at 600°C, are observed, when water vapor bubbles form within the mica and expand ...

Neoarchaean and Palaeoproterozoic tectono-metamorphic events along the southern margin of the Zimbabwe craton: Insights from muscovite 40Ar/39Ar geochronology from rare-metal pegmatites, Zimbabwe

Muscovite 40Ar/39Ar geochronology on ten samples from complex-type, rare-metal (e.g., Li, Cs, Ta, Rb, Be, Nb, Sn and W) pegmatites from the Bikita and Mweza pegmatite fields in Zimbabwe yield ages that range from ca. 2622–1940 Ma.
