Book Review Impact structures in Canada, by Richard A. F. Grieve. Geological Association of Canada, , p., $60 (Canadian dollars), hardback (ISBN ). Cratonic regions of the world provide rich libraries of remnant impact craters, and Canada is one of the richest among them. For nearly six decades, Canadian scientists haveAuthor: David A. Kring.

Even after the rapid drop in crater production rate after the end of the Late Heavy Bombardment, the impact cratering has remained the most common surface-shaping process for all the solid bodies of our Solar System.

This list includes all 60 confirmed impact craters in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth.

For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface g: Shock Zoning. Manicouagan Crater, located in Canadian province of Québec, is one of the Earth’s oldest and the most visible impact craters.

Manicouagan Crater was formed by an asteroid strike over million years ago. Like a pebble creating ripples when dropped into water, the crater has concentric rings formed by shock waves transmitted by the : Caitlin Dempsey. crater is the most persuasive evidence for an impact origin, but the criterion is not ubiquitously applicable.

For impact events that form craters larger than roughly km across, the shock pressures and temperatures produced upon impact are sufficient to completely melt. Evidence for the collision of fragmented comets or asteroids with some of the larger (jovian) planets and their moons is now well established following the dramatic impact of the disrupted comet.

It is 65 kilometers (40 miles) in diameter, but it is worth remembering that this is small compared with some of the larger lunar structures that measure more than km ( miles) across. New crater size-shape data were compiled for fresh lunar craters and youthful mercurian craters. Terraces and central peaks develop initially in fresh craters on the Moon in the 0–10 km diameter interval.

Above a diameter of 65 km all craters are terraced and have central by: Mistastin crater is a meteorite crater in Labrador, Canada which contains the roughly circular Mistastin Lake.
