Description- This material has a H.H. Nininger provenance. The impactite "bomblets", as Nininger called them, are small impact pieces. Upon examination under a 60 power loupe, aerodynamic shapes are clearly defined in some of the pieces. (see photos)
Location- Meteor Crater in Arizona; the world's best preserved meteorite impact crater.
Weight- Vial contains 1.0 grams
Measurements- The vial measures 38 x 12 mm. Bomblets measure between 1 to 3 mm at their widest.
The Nininger label on the jar reads "Impactite bomblets from depth 4 to 5 ft. in pit on N.N.W. lower "half"(? illegible) of Crater rim.". The label inside the jar reads "Bomblets taken from 4 - 5 ft depth in excavation, passed 16 mesh caught by 24, no volcanics, no acid used, contents of this jar represents approx. 200 hrs. of magnetic separation by use of hand magnet."
