Cavansite is a calcium vanadium silicate. Staples et al. (1973) named the mineral after the first few letters of its chemical components. The mineral was originally found in Oregon, along with its polymorph, which have now been found in India in much greater crystal sizes and quantities of specimens.

Cavansite here forms minute needles to 0.5 mm with curved calcite crystals. Cavansite and calcite form a triangular coverage, 2.4 by 1.6 cm, on altered volcanic rock. This specimen was part of the Charles Trantham (1936-2020) estate.
