Mineral Identification

Marcasite is an iron sulphide mineral and the orthorhombic polymorph of pyrite. The term “opalised marcasite” indicates that the specimen is presented with an opalised character associated with the marcasite identification. This combination gives the piece a specialised collecting interest for those who enjoy mineralogical varieties, altered mineral textures and geological specimens with an unusual appearance. The Grade A designation is part of the supplied product identification.

Geological Context

The specimen is identified as Miocene. The Miocene is a recognised epoch of the Neogene Period, extending from approximately 23.0 to 5.3 million years ago. In a mineral and geological collection, a Miocene identification provides useful chronological context and connects the specimen with geological materials formed during a clearly defined interval of Earth history.
