ENERGY-DISPERSIVE X-RAY FLUORESCENCE (EDXRF) ANALYSIS OF MAJOR OXIDE AND TRACE ELEMENT CONCENTRATIONS FOR RHYOLITE AND DACITE PROJECTILE POINT FRAGMENTS FROM THE TULAROSA BASIN, SOUTHERN NEW MEXICO [PDF]
The non-destructive whole rock analysis here of three projectile point fragments from unknown provenience in the Tularosa Basin of southern New Mexico indicates that one of the artifacts was likely produced from the Socorro hydrothermally altered ...

Dacite origins during a compositional shift in eruptive products at Middle Sister volcano, Oregon Cascades [PDF]
The Three Sisters Volcanic Complex (TSVC) in the Oregon Cascades provides a unique framework for investigating trans-crustal magmatic systems and intermediate magma petrogenesis at arc systems, due to its compositional variability (erupting the full ...
