Trace element and Sr isotopic geochemistry have been used to demonstrate what happens chemically to the rocks that have been hit and melted by the impact of a meteorite.
Two meteorite craters were studied by these techniques. The one in Labrador has a simple geology and this has allowed the construction of a model of the geochemical processes involved in the impact of a meteorite. The other, at Sudbury, has a much more complex geological history which does not allow the direct application of the model because of post-crater events.
