The quoted uncertainties are the standard deviations shown by replicate measurements on a single aliquot.
COMMENTS: The following comments are based on natural TL data, TL sensitivity, the shape of the induced TL glow curve, classifications, and JSC and Arkansas sample descriptions.
QUE 97030 is confirmed as type 3.4 by TL sensitivity (AMN 22:1). QUE 97014 and QUE 97053 have TL sensitivities similar to eucrites of petrologic type 5 in the classification system of Takeda et al. (1983, Proc. 8th Symp. Antarctic Meteor., 181-205) and Batchelor and Sears (1991, GCA, 55, 3831-3844). It is, however, possible that QUE 97053 has a low TL sensitivity due to shock processing (AMN 22:1). Pairings suggested by TL data:
