PhysOrg: New finding could inform how zeolites are used in carbon capture and storage

„Filled with microscopic holes and channels, these ultraporous minerals can soak up environmental contaminants, filter drinking water, manage nuclear waste and even absorb carbon dioxide (CO2).Now, in the first study of its kind, Northwestern University researchers have analyzed ancient zeolite specimens collected from the edges of East Iceland to discover that zeolites separate calcium isotopes in a wholly unexpected way.“
