Global Mars Crater Database, Complete to 1 km

Every red dot on the globe is a single crater larger than 1 km in diameter. This work comes from a published paper by Robbins and Hynek in the Journal of Geophysical Research that came out in 2012. (There is no audio to the video.)

yes, I find it interesting, but don't k now what the commonly held theory(ies) is(are). A later large impact?

Yes, The large basins are just really big craters. Argyre and Hellas, the two in the south you referred to, are around 1500 and 2300 km across, respectively. Formed very early in Mars' history (around 3.95 billion years ago and around 4.1 billion years ago, respectively).

Any theories about the 2 large impact craters in the South?

[astrostu206265]

Are you talking about the large basins, Argyre and Hellas? There's been a lot of study about them in the past, and these craters are being used by different groups to understand some of their history.
