I am in Tenerife. Today was very long day in the field. I am too tired to write a lengthy post. But I would like to share at least one picture with you.
This is pyroclastic sequence which is composed of dark layers of scoria and light-colored layer of phonolitic pumice fall deposit between them. Pumice layer is a product of violent plinian eruption farther away. Scoriaceous mafic dark-colored lapilli were ejected from nearby vents (strombolian eruptions). You can also see a minor fault running through the outcrop.
Here are the coordinates of the outcrop: 28° 20′ 02″ N 16° 27′ 50″ W. Altitude 1970 meters.
