| Abstract | Northwest Africa (NWA) 10416, weighing 964 g was found in Mali, 2015. It is an olivine-phyric shergottite with a high degree of alteration present within it, unusual for shergottites. The olivine megacrysts show amber-brown altered cores and clear unaltered rims (Fig. 1), distinctive concentric colourations not previously reported in the olivine-phyric shergottites. The groundmass plagioclase and maskelynite have also been extensively altered to a secondary phase. Here we report on the petrology and alteration history of the olivine-phyric shergottite, NWA 10416, paying particular attention to the origin of the aqueous alteration seen within the meteorite. |
