A Diagnostic Impact Criteria List to Confirm Terrestrial Impact Craters by the Meteoritical Society Impact Cratering Committee — Work in Progress
[#6248]
The Meteoritical Society Impact Cratering Committee is evaluating which features constitute diagnostic evidence that can be used to confirm terrestrial impact craters. The information will be used to compile a list of confirmed impact craters.

New Evidence for an Endogenic Origin of the Talemzane Crater (Algeria)
[#6103]
A seismic section across the Talemzane crater (Algeria) reveals the presence of a narrow, disturbed zone just below the structure. The presence of this deep seismic anomaly seems to favour an endogenous origin (rising salt or gas) for this crater.

Geophysical Update of the Diameter of the Zhamanshin Impact Crater (Kazakhstan)
[#6172]
Using new potential-field and passive seismic measurements over the Zhamanshin impact structure in Kazakhstan, we propose to revise the apparent diameter from 14 km to only 6 km. The impact crater is almost entirely buried.

The Case for a Peak Ring Morphology for the Morokweng Impact Structure
[#6255]
Based on lithological, geophysical, geochemical, structural and petrographic data from the M4 drill core in the Morokweng impact structure we propose the intersected rock volume represents the eroded peak ring of an ~80 km wide crater.

Stratigraphic Uplift in the Central Area of Ouarkziz Transitional Crater (Algeria)
[#6042]
Ouarkziz is classified as a transitional structure with six others in the world. Based on its diameter alone it is a complex crater; however, no central peak is observed in the central area.
