Dimmitt is one of the largest meteorites known from North America; many hundreds of kilograms of fragments and individuals have been recovered from the plains around Dimmitt, Texas. This find is all the more important because it is an unequillibrated, gas-bearing regolith breccia from the surface of an asteroid. Most of the meteorite is composed of primitive material, but other pristine xenoliths have also been worked into the rock. Strangely, the largest single stones recovered from the fall have weighed less than ~ten kilograms, though this may be due to larger stones lying below the reach of plows. Here are a few papers that looked at Dimmit to draw some interesting conclusions:
Here are a few stones we’ve been fortunate to acquire over the years. Complete non-NWA stones can be tough to find, and these often get cut to bits, so we’ve accumulated a few of them. The largest stone is a little over 2 kilograms (oriented), and the total weight of the lot is ~6 kg.
