Meteorite impact picture of the month

In the future we will present interesting pictures – megascopic to microscopic – from the world of our impact research in roughly monthly intervals. A small accompanying text explains the presentation and, where appropriate, links to further pages are given.

A typical polymictic impact breccia with breccia generations (breccias-within-breccias-within-breccias) – Crooked Creek impact structure, Missouri) – Arnold Spitzer collection.

Moldavite tektite

Artifact-in-impactite – worldwide novelty

Impact shock feature: ballen structures from four new impact sites in Central Europe (Germany, Czech Republic)

Impact feature: thermal shock in quartz

Chiemite – carbon impact rock (impactite) – the Chiemgau impact event as namesake

Ground Penetrating Radar (GPR): Emmerting #004 crater, Chiemgau meteorite impact strewn field (Bavaria, Southeast Germany)

Impact breccia in lapillistone matrix. – Rubielos de la Cérida impact basin (Spain) near Olalla.

Polymictic impact breccia dike sharply cutting through well-bedded Muschelkalk limestone. – Rubielos de la Cérida impact basin (Spain) near Olalla.

Impact sulfate melt rock from the Rubielos de la Cérida  impact basin (Azuara impact event, Spain) – a rare meteorite impact signature

Trigonal and cubic Fe2Si polymorphs (hapkeite) in the eight kilograms find of natural iron silicide – a probably new class of meteorites

Enigmatic Impact Breccias Probably Linked to the Ries Crater (Germany) Impact Event -Alemonites from Bavaria and sunstones from the Czech Republic

Impact spallation – completely underestimated by impact researchers.

Rock fluidization, Azuara Impact Structure (Spain)

Shocked calcite

shocked calcite multiple sets of planar deformation features Rubielos de la Cérida impact

Shock effect in calcite. Multiple sets of closely spaced planar features (micro twins). The width of the twins is of the order of only one micrometer. Thin section micrograph, crossed polarizers. From a polymictic breccia, rim region of the Rubielos de la Cérida impact basin crater chain.
