Waconda, Rare Kansas L6 Find, ex-Dietz Coll, Micromount



Waconda is a L6 chondrite first discovered in a Kansas farm field prior to 1871. Of the history of the stone little is known except the weight of the stone when secured in 1873 was about 120 pounds. Several persons remember to have seen it in the same locality as early as 1870 at the time of the first settlement of the town but at that time it attracted no special attention.

The stone was broken into several pieces (largest 26.3 kg). Olivine composition (Fa25) is characteristic of L (low iron) ordinary chondrites. A number of opaque minerals were reported by Ramdohr, 1973. The meteorite was also part of the Stöffler et al. (1991) work which established the framework for determining the current shock levels of ordinary chondrites. The meteorite is considerably weathered. Approximately half of the original mass [25.9572 kg - July 2016] is at Arizona State University's Center for Meteorite Studies.

The material being offered here was part of the Robert S. Dietz collection (a respected scientist, Google him for more information) and was deaccessioned from a major university collection. This specimen is a fragment that weighs .67 grams and comes with the labeled glass vial from the university.
