Troodos extrusive series of Cyprus; a comparison with oceanic crust

1,000 to 1,500 m thick and consists of 12 lithologic units of pillowed and massive lava and breccia. Episodic volcanic accretion. Fresh volcanic glass throughout most of the section. Lavas are subdivided into a lower, differentiated andesite to dacite series and an upper series of mafic basalts and...

Description
Summary:1,000 to 1,500 m thick and consists of 12 lithologic units of pillowed and massive lava and breccia. Episodic volcanic accretion. Fresh volcanic glass throughout most of the section. Lavas are subdivided into a lower, differentiated andesite to dacite series and an upper series of mafic basalts and basaltic andesites. Lateral continuity of lithologic units interpreted as individual volcanoes. Occurrence of fractionated lavas at the base and primitive lavas at the top suggests a broad zone of accretion, located above a subduction zone.—Modified journal abstract.
