Notes

In organizing the list here, I have followed the following principles:

Where do I find this stuff? Public libraries almost never will have any of these references. Most colleges and universities that have a geology program will carry Geology and other common publications. For the more obscure publications you may have to try a very large university or resort to inter-library loan, or in extreme cases write to the authors or publishers. Welcome to my world.

Unless meteoritic fragments have been found at a site, almost every large impact site has been claimed to be of terrestrial rather than extraterrestrial origin. Even meteorites aren't always enough; for years some geologists argued that Meteor Crater was a volcanic crater and the meteorites nearby were just a coincidence. See the references for Upheaval Dome for both sides of an ongoing controversy. Some early references date from before the recognition of certain sites as impact craters, and though the geology may be described accurately, it may not always be interpreted in terms of impact.

No two lists of sites are exactly alike. Meteorite fragments are conclusive but found only at small, recent craters. Shock metamorphism, especially high-pressure minerals like diamond or coesite, and shatter cones are widely regarded as conclusive. Structural disturbance of the rocks, circularity, and so on are suggestive but not conclusive. Sites reported as impact sites in reputable current scientific literature are included, but some might be controversial and could eventually turn out not to be of impact origin (again, see Upheaval Dome). Older lists should be taken with a grain of salt since they were compiled when our understanding of impact was a lot less and can include sites no longer considered to be impact sites.

Foreign names are often rendered in different ways and a few entries have different spellings that may or may not refer to two different sites.
