EarthRef.org Digital Archive (ERDA) -- Extrusive Series of a Seamount Sequence

Description
Interpretive section through the 1800 m thick extrusive series of a seamount sequences on La Palma. It starts on top of a sequence dominated by dikes and sill intrusions, and shows a transition from mostly thick pillow deposits to highly fragmented pillow breccias and hyaloclastites. This sequence also shows the transition from a mostly effusive deep water stage to a dominantly clastic intermediate and shallow water stage. The depth, given as stratigraphic depth measured from the top of the submarine extrusive series, corresponds to a minimum eruption depth.

Keywords
