Apollo 11 and 12 mare basalts and gabbros: Classification, compositional variations, and possible petrogenetic relations Apollo 11 and 12 mare basalts and gabbros: Classification, compositional variations, and possible petrogenetic relations
On the basis of composition, it is possible to distinguish three major groups of Apollo 12 basaltic rocks: olivine-pigeonite basalts and gabbros, ilmenite-bearing basalts and gabbros, and feldspathic basalts. Two major groups of Apollo 11 basalts are also distinguishable: ophitic ilmenite basalts and intersertal ilmenite basalts. Compositional variations between samples within groups are...

Volcanic stratigraphy of the Quaternary rhyolite plateau in Yellowstone National Park Volcanic stratigraphy of the Quaternary rhyolite plateau in Yellowstone National Park
The volcanic sequence of the Quaternary Yellowstone plateau consists of rhyolites and basalts representing three volcanic cycles. The major events of each cycle were eruption of a voluminous ash-flow sheet and formation of a large collapse caldera. Lesser events of each cycle were eruption of precaldera and postcaldera rhyolitic lava flows and marginal basaltic lavas. The three major ash...
