KRöHNKITE SPECIMENS

Kröhnkite is a rare copper sulfate mineral named after B. Kröhnke who first researched it. It has the same general formula as minerals which are found in environments affected by hydrothermal alteration, making it important in identifying where such alterations have occurred. Furthermore, the minerals sharing this composition are organized according to three crystal structure types, one being the unique kröhnkite structure which is often used to describe minerals exhibiting the same chain-like structure.
