Friability of Meteorites
This bundle contains the complete experimental dataset and visual documentation from the friability analysis of seven meteorites: Richardton (H5), Tamdakht (H5), Zhob (H3/4), New Concord (L6), Allende (CV3), Murchison (CM2), and Aguas Zarcas (CM2). The dataset records the mass retained in each sieve bin after successive tumbling stages of 10, 100, 1,000, 10,000, and 100,000 revolutions, performed using the PTF-100 friability tester. All measurements were conducted according to the USP 1216 friability standard, using a 28.7 cm diameter drum that rotated at 25 rpm. Corresponding sieve sizes are 2000, 841, 400, 250, 177, 125, 63, 37, and 0.1. The data quantify the progressive mechanical disaggregation and redistribution of fragment sizes across increasing revolution counts, providing a quantitative basis for modeling the friability of meteorites. Seven chondritic meteorites representing diverse lithologies. The archive enables reproduction of all plots and calculations related to the evolution of friability as a bounded, multiplicative process, and provides a benchmark for linking laboratory comminution to asteroid surface processes.
