Conichalcite is a copper mineral (CaCu(AsO4)(OH))
Conichalcite is including (growing inside) the calcite crystals. We bought a mineral treasure hoard a few years ago from a family that traveled to Mexico in the 70's and 80's. These had been tucked away for years and had never been on the mineral market. They were so unusual an expert on Mexican minerals insisted on taking a small sample and having it analyzed in his laboratory. The results are in and this is conichalcite.
A little mineral trivia. "cal" from the Latin for lime. "Chalc" is from the Greek khalkos for Copper.
So for coniChalcite it refers to the copper content.
