Abstract

The micromorphology and elemental composition of celestobarite crystals in a duripan from central Australia are examined. These crystals are flabellate (fan-shaped), have a Ba/Sr ratio of 11.1, and are up to 50 μm in size. The location of the celestobarite crystals within silicified roots and in close association with calcite and clay coatings indicates that these celestobarite crystals are authigenic and were formed under aridic environments.
