Abstract
Petrographic, mineralogical and bulk chemical data are presented for three of approximately 25 L‐group chondrites with which we are attempting to define and interpret major element chemical variations in the L‐group. Two of these unbrecciated L6 chondrites ‐ Aïr and Apt ‐ have olivine and feldspar characteristics that testify to shock pressures of approximately 240–260 kb; they contain sparse veins and pockets of glass. The third, Tourinnes‐la‐Grosse, experienced a lower shock pressure and lacks such evidence of melting.
