Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Cosmic Rays and Galactic Winds

Astrophysics and Space Science, 2004
Repeated SN-explosion provide large amounts of thermal energy as well as energetic particles through a 1. order Fermi-process. Both effects together with the generation of AlfveŽn-waves are considered to drive a large scale outflow from a galaxy. These so-called galactic winds transport stellar material enriched by heavy elements into the intergalactic

Galactic winds: a short review

Astrophysics and Space Science, 2007
Galactic winds are important in recycling energy and metals in galaxies. They are also suspected to be the primary mechanism in the enrichment of the intergalactic medium. New observations are revealing the ubiquity of galactic winds, particularly at high redshift. We review the observational evidence for them in nearby star-forming and active galaxies

Galactic winds in dwarf galaxies

New Astronomy Reviews, 2007
Abstract Galactic winds are mayor ingredients of our current paradigms of galaxy formation and evolution. They are needed to explain the chemical evolution of galaxies and the intergalactic medium, the luminosity function of galaxies, the formation of galaxies, and the reionization of the universe, just to name a few topics.
