- wanderr 8y agopelagic_sky's link to the study is useful, I'm not sure why their comment is dead: http://advances.sciencemag.org/content/4/11/eaar8173 http://advances.sciencemag.org/content/4/11/eaar8173

- duxup 8y ago>Some of the minerals they analyzed exhibited the telltale characteristics of a catastrophic impact, such as shocked quartz grains and other impact-related grains, such as glass. Forgive me for my poor terminology here as this isn't my area. Considering they found the signs of the impact, and other impacts like the Chicxulub Crater have left similar debris / signs in soil samples. Are we at the point now where we can take soil samples in an area and without finding a creator see that there was a large impact somewhere (near or far) around a specific time based on the soil date?
