Introduction: The HEDs make up the largest suite of crustal igneous rocks available from asteroids. Sili-cate clasts in the mesosiderite metal-silicate breccias are also dominated by crustal rocks that resemble the HEDs in many ways. Silicate petrology in both groups of meteorites range from strikingly similar fine-grained basalts to coarse grained orthopyroxenites. Mesosid-erites furthermore c...

Magma genesis, migration, and eruption have played prominent roles in the chemical differentiation of the Earth. Plate tectonics has provided the framework of tectonic environments for different suites of igneous rocks and the dynamic mechanisms for moving masses of rock into melting regions. Petrology is rooted in geophysics. Petrological and geophysical processes are calibrated by the phase e...

The core-mantle boundary region is often considered to be the source of narrow upwellings which drive or influence plate motions and continental breakup, fuel large igneous provinces and generate volcanic chains. The plume hypothesis has influenced most fields of geochemistry, petrology, geodynamics and mantle evolution. The key axioms underlying the plume paradigm are identified: Axioms are se...

Forging a link between quantitative skills and geologic problem solving is a valuable instructional approach that can guide the development of quantitative course material. A conceptual framework is presented that shows how various research tasks (for example, data collection and hypothesis development) employ certain combinations of quantitative skills (for example, graphical presentation and ...

Introduction: Chondrules are sub-mm to mm-sized igneous inclusions that can comprise up to ~80% of the primitive meteorites called chondrites, and provide us with snapshots of the solar nebula. They are the key to understanding the early history of the Solar System and the formation of terrestrial planets. Chondrules formed in the first few million years (Myr) of the Solar System’s history [e.g...
