Hello Rhett and List, Clipperton may be one of those meteorites about which Pierre cautioned: "is there systematic bias? (possible for weathered finds, oxidation of olivine starts by turning Fe to rust there- fore decreasing Fa%" because it was collected from the ocean floor and is highly weathered. Grady (1937), H3.6 has 26.23 % total iron Moorabie, L3.8: 22.34 % - 22.68 % total iron, olivine Fa14 (5-20); pyroxene Fs3-29; Quinyambie, LL3.4: 19.0 % - 19.48 % total iron; olivine Fa22 (5-35); pyroxene Fs15-30; Willaroy, H3.5: 25.3 % total iron, olivine Fa15 (10-19); Xinyi, H5: 26.9 % total iron, olivine Fa15; QUE 94570: Fa10-13, Fs9-12 but caution (!) - it, too, was extremely weathered, when it was found. QUE 94570 was originally classified as a C4 chondrite, but see: KALLEMEYN G.W. et al. (1998) Prompt-Gamma Analysis (PGA) and Instrumental Neutron Activation Analysis (INAA) studies of a new reduced L chondrite (Meteoritics 33-4, 1998, A081): "Our analyses show that QUE 94570 is not, in fact, a new member of the Coolidge-Loongana 001 grouplet, but is rather a new L chondrite similar to Moorabie and Suwahib Buwah."
