Geochemistry data for bedrock volcanic samples listed in Table 1 Volcanic Rock Samples. Samples collected from the Mushroom Rock region, northeastern California.
-
Mineral compositions are reported for Quaternary volcanic rocks of the Matan volcanic center, northern Harrat Rahat, Saudi Arabia. Compositions were measured by wavelength-dispersive methods with...

This dataset contains 40Ar/39Ar data and ages for volcanic rocks in the Mushroom Rock region, northeastern California
-
This data set represents the presence or absence of basalt and volcanic rocks in the conterminous United States. The data set was used as an input data layer for a national model to predict...

While the timing and composition of the Yellowstone Plateau volcanic field’s caldera-forming tuffs and rhyolite flows are well-characterized, the chronology of smaller-volume mafic eruptions is...
-
This dataset is the assembled analytical results of geochemical, petrographic, and geochronologic data for samples, principally those of unmineralized Tertiary volcanic rocks, from the Tonopah,...
