One of my own ( Shitasoaras I need to add this to my stuff)
Pyrite on Calcite
El Hammam Mine Meknes, Fes-Meknes Region, Morocco
Pyrite often times after forming from Hydrothermal activity or bacterial processes clings to surfaces with edges and groves that share similar geological settings. Being that Calcite is often plentiful in the area and forms first it's a perfect setting for the Pyrite to grow.
This is a first for me. I have plenty of Pyrite on Quartz but not Calcite.
