Aragonite over Calcite from Limpopo Province (formerly Transvaal), South Africa

DESCRIPTION:No. 37593
Mineral:Aragonite over Calcite
Locality:Limpopo Province (formerly Transvaal), South Africa
Description:Elongated transparent colorless aragonite crystals up to 5 mm over milky white calcite crystals. Since both minerals are CaCO3, I suspect the mineral identification is based on morphology rather than XRD. Both minerals fluoresce brightly under UV. Ex. Robert C. Lambert (1919-2008) collection #RL489
Overall Size:8x7x4 cm
Crystals:1-5 mm
Archived: For reference only
