[meteorite-list] Related Meteorite Falls 11 years apart? Both Hammers! Both L6 Olivine-hypersthene

Walter,
Yes,  there are documented strewnfields which prove more than one classification does exist within a single area. But, Now that Almahatta Sitta has been found to have several different classes within one fall it seems to me this changes everything.
In fact as you know they were so confused by the differences that they tested every single find to be absolutely sure they were all from just one fall. I believe they decided that they were in fact all from one fall. This makes buying and selling Almahatta Sitta a bit tricky because you may not actually get the Ureilite you are expecting. You may get some other classification all together. 
It has been widely speculated that this fall was a real smorgasbord of many different types that possibly all collided together  in space at some point prior to colliding with Earth. 
In addition there are two distinct irons that have been found within the Canyon Diablo strewnfield just to name one more. . Nininger refers to the second higher nickel one as CD 2,  I believe. 
So, What this might tell us is that our past Science about overlapping strewnfields may have been the wrong theory. Maybe these odd balls hit and mix elsewhere in space and land together on Earth. They don't even have to be the same age or the same class for that matter. Who is to say that an old fall did not collide with a newer fall while still in space? Seems to me we may need to rethink and recheck this whole theory. Carl
