Tenerife

There are mostly Zeolithes on Tenerife, but not as much as on the other islands. I managed to find a few. The vulcanic landscape is great there! Mindat:

“The largest of the Canary Islands (and the most densely populated). Under-sea volcanic eruptions created the island base 20-50 mya. Subaerial eruptions created three distinct islands at the end of the Miocene (about 7 mya), represented by the present-day Anaga, Teno and Adeje massifs. About 3 million years ago, a further cycle of eruptions joined the islands into one. Today, Tenerife is dominated by the central Pico del Teide-Pico Viejo volcanoes and Las Cañadas caldera. Teide (3718 m) last erupted in 1909 and is considered a dangerous stratovolcano; it bulges on the northern flank, has several active fumaroles and seismic activity has occurred periodically since 2003.”

Some pictures of the vulcanic landscape are added at the Spain main page.
