Bowie glass and whole-rock analyses span a wide range of compositions, from
basanite to near-trachyte, and cover the entire compositional range for the Pratt--Welker and other Gulf of Alaska seamount chains (Fig.
Glass in the Baarley xenoliths has three different origins: infiltration of an early host melt different in composition from the erupted host
basanite; partial melting of amphibole; reaction of either of these melts with xenolith minerals.
Based on the chemical analysis, they are classified into dominant alkali olivine basalts and
basanites with minor olivine tholeiites.
4c and d).The volcanics in Bhm where least altered are petrographically
basanite and alkali- basalt contain phenocrysts of olivine and augite with a groundmass consisting of plagioclase, pargasite, phlogopite and opaque and glassy material.
Other famous mineralogical locality of zeolites (natrolite, analcime, phillipsite, mesolite, thomsonite) together with apophyllite, calcite and chlorite was described by Bouska and Malec (1971) in amygdales of a
basanite intrusion near Soutesky.
Predominance of sulphates (mikasaite,
basanite and anhydrite) over pyrite was identified by X-ray powder diffraction, and pyrite was identified only in samples 2 and 4 (Table 3, Fig.

Basanites and crustal contamination in the Cartagena volcano field (South-East of Spain).
The volcanics are mainly
basanites and tephrites, mildly to strongly alkaline, and akin to the intra-plate volcanic rock series.
