>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.<p>Forgive me for my poor terminology here as this isn't my area.<p>Considering they found the signs of the impact, and other impacts like the Chicxulub Crater have left similar debris / signs in soil samples.<p>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?
