This sample can be classified using the Dunham/Folk Classification. Grains: mostly carbonate but some qtz. Sparite: 10%, Micrite: 60%. Non-skeletal grains: Monocryst qtz. Skeletal grains: Crinoid ossicles, echinoderm fragments (mostly), spines, forams, ostracods. Classification: Bioclast-rich pelmicrite / packstone . Diagenesis: Pressure solution seams / stylolites run through thin section. Lots of grains are broken and incomplete - high energy environment?
A group of iCRAG members (UCC, TCD, NUIG and UCD) in partnership with The Open University have created a new collection of Irish rocks and associated learning materials for the Virtual Microscope of Earth Sciences.
The project which is entitled 'The Geoscience e-Laboratory (Geo-LAB): Developing Digital Teaching and Learning Resources for the Virtual Microscope' seeks to develop open access teaching resources in the form of interactive exercises and assessment rubrics for the Virtual Microscope.
