Green opals in hydrothermalized basalts (Tenerife Island, Spain): alteration and aging of silica pseudoglass

Green opals have been identified in veins and vugs in hydrothermalized basalts from the area of Taganana (Tenerife). The aim of this paper is to document the petrology and geochemistry of these opals and to describe the formation process from amorphous components. Green opals were studied using opti...
