...) and the axinite-(Fe) end-members. We report data on the composition of axinite-(Mn) and the formation conditions of axinite-containing mineral assemblages in miarolitic granitic pegmatites of the Malkhan gem-tourmaline deposit. Axinite-(Mn) occurs only in the pockets in which Li-Al tourmaline (rubellite...

... enriched in metasedimentary xenoliths. Muscovite extracted from aplite, pegmatite and quartz – muscovite – tourmaline pocket zones give flat 40 Ar/ 39 Ar age spectra with 370 Ma plateau ages. Petrographic observations indicate rapid post-crystallization cooling and minimal deuteric alteration, although...

... and New Meadows, Idaho, along U.S. Highway 95. West-central Idaho has played a leading role in identifying and interpreting geologic and geochemical features of collisional margins in the North American Cordillera (Fig. 1 ). The pioneering fieldwork of Hamilton (1960, 1962, 1963a, 1963b, 1969...

... fluctuations in element concentrations that attest to episodic cycles of growth. One can envision periodic sealing of the pocket zone, as Jahns (1982) proposed, during which closed-system growth takes place, followed to repeated reopening of the system. Thus the beginning of each new zone is marked...
