The fundamental approach for the confirmation of any terrestrial meteorite impact structure is
the identification of diagnostic shock metamorphic features, together with the physical and …

Studies of impact structures in Sweden date back almost 60 years. They have so far resulted
in the confirmation and understanding of eight impact structures and one impact-derived …

Planar deformation features (PDF s) in quartz are the most widely used indicator of shock
metamorphism in terrestrial rocks. They can also be used for estimating average shock …

Discordant U–Pb data of zircon are commonly attributed to Pb loss from domains with
variable degree of radiation damage that resulted from α-decay of U and Th, which often …

Finding direct records of the ancient Earth's atmosphere is key to understand the evolution of
the entire planet. Nevertheless, such records are scarce, and only a few geological samples …

Heat-flow data from deep boreholes are of particular value as a number of factors, including
climatic surface temperature variations, may disturb subsurface thermal conditions …

Impact cratering is associated with extreme physical conditions with temperatures and
pressures far exceeding conditions otherwise prevailing at the surfaces of terrestrial planets …

Shocked quartz and feldspar grains commonly exhibit planar microstructures, such as
planar fractures, planar deformation features, and possibly microtwins, which are considered …

Little is known about the microstructural behavior of magnetite during hypervelocity impact
events, even though it is a widespread accessory mineral and an important magnetic carrier …

The Ilkurlka structure is an~ 12 km diameter buried circular aeromagnetic anomaly within the
Officer Basin in Western Australia. Prior studies postulated a range of origins, including …
