Anorthite-calibrated backscattered electron profiles, trace elements, and growth textures in feldspars from the Teide-Pico Viejo volcanic complex (Tenerife)

Correlations between zonation patterns of single crystals in different rocks show that the Teide magma chambers are larger and chemically buffered compared with the smaller Pico Viejo system. Feldspars from Pico Viejo exhibit rather complex anorthite-profiles and more frequently display disturbances likely to be caused by arrival of new magma batches.
