Title Description

About this title

This volume is a collection of papers to celebrate the life and work of Professor lan Gass. The research themes cover many of the subjects which most interested him, especially processes operating in oceanic crust. The introductory papers examine evolution of magmas from mantle melting to eruption. A central section concerns ophiolite complexes. Several papers focus on different aspects of the Troodos ophiolite complex in Cyprus, where lan first recognized that sheeted dykes within the ophiolite sequence must have formed in an oceanic spreading environment. In addition, ophiolites ,are reviewed and examined in terms of tectonics, magmatic and mantle textures, metallogenesis and hydrothermal alteration. A further section concentrates on tectonics and the genesis of magmas associated with collision and subduction. This contrasts with continental rifting and the effects of mantle plumes.

This collection of papers covers a broad range of topics from processes in the mantle to those in the oceanic crust. The volume will be of interest to all scientists concerned with igneous processes and global tectonics.
