| Abstract: | The size frequency distributions of fluid drop chondrules in 11 ordinary chondrites (five H3, one H4, four L3, one LL3) have been determined by optical measurements in petrographic thin sections. The extreme range of median size of the fluid drop chondrules in individual meteorites is only slightly greater than lφ unit, and the grain size frequency distributions are approximately log normal. Chondrule size frequency distributions generally are fine skewed, platykurtic, and indicate moderate sorting. The size frequency distributions of fluid drop chondrules in ordinary chondrites are distinctly coarser than similar chondrules measured previously in CM2 and C03 carbonaceous chondrites. |
