Extensive and ancient feldspathic crust detected across north Hellas rim, Mars: Possible implications for primary crust formation

Autor: Michael S. Phillips, Christina E. Viviano, Jeffrey E. Moersch, A. Deanne Rogers, Harry Y. McSween, Frank P. Seelos

Publikováno v: Geology. 50:1182-1186

Due to its size and observable record of ancient rock, Mars is key to understanding crustal formation on planetary bodies, including Venus and Earth, which may have derived their first stable crust from mantle-overturn melting. Recent evidence that a

Evidence for early fragmentation-reassembly of ordinary chondrite (H, L, and LL) parent bodies from REE-in-two-pyroxene thermometry

Autor: Nathaniel R Miller, Jialong Ren, Nick Dygert, Harry Y. McSween, Marc A. Hesse, Michael P. Lucas

Publikováno v: Geochimica et Cosmochimica Acta. 290:366-390

Ordinary chondrites (OCs) are variably thermally metamorphosed meteorites thought to originate from at least three different parent bodies (H, L, and LL) in the Main Belt of asteroids. The thermal evolutions of OC parent bodies are frequently explain

Petrology and geochemistry of olivine-phyric shergottites LAR 12095 and LAR 12240: Implications for their petrogenetic history on Mars

Autor: E. T. Dunham, Thomas G. Sharp, Meenakshi Wadhwa, Harry Y. McSween, J. Brian Balta

Publikováno v: Meteoritics & planetary science

Larkman Nunatak (LAR) 12095 and LAR 12240 are recent olivine-phyric shergottite lnds. We report the results of petrographic and chemical analyses of these two samples to understand their petrogenesis on Mars. Based on our analyses, we suggest that th

Publikováno v: Icarus. 318:42-55

Combined analyses of the surface elemental composition and mineralogy of Vesta and Ceres provide insights into their interior evolution, crustal formation, and regolith processes. Compositional data acquired by Dawn's Visible to Infrared Mapping Spec
