...James D. Webster; Wendell A. Duffield Abstract Crystal-bearing glass inclusions are hosted by quartz phenocrysts in eruptive units of the tin-mineralized Taylor Creek Rhyolite, New Mexico. Inclusions from four units were refused at 2 to 4 kbars and temperatures > or = 890 degrees C and analyzed...

... data of Tilton and others (1981) supports a mantle component in the Cordillera Real melts. The Cordillera Real granites are characterized by high tin contents. Geochemical indicators such as TiO 2 content and Rb/Sr, Rb/Ba, and Mg/Li ratios suggest that the tin was introduced by assimilation during...
