| On the Moore's Station piece: The pyrite appears to be in lines. Is that so, and are those lines on edges of the calcite crystals?

The micro pyrite crystals are randomly scattered about the stilbite, and included in and on the calcite crystals. Greater pyrite concentrations are situated along the edges of approximately half the calcites, giving a linear appearance.
