Massive Volcanic Glass: Natural Pozzolan in the West of São Paulo State

Massive Volcanic Glass: Natural Pozzolan in the West of São Paulo State

Some occurrences of massive volcanic glass have been recorded in the western region of São Paulo State duringgeological mapping and prospecting and technological characterization of pozzolanic materials. The massive volcanic glassis associated with trachydacites from the Serra Geral Formation. The g...
