Neo-volcanic ridge
Definition
Axial volcanic ridges (AVRs). Composite volcanic edifices, comprising an elongate, typically spreading-normal orientated topographic high, produced within the inner valleys of mid-ocean ridges, usually those that are slow spreading.
Introduction
The surface expression of volcanic activity is extremely variable at different spreading rates (see “Morphology Across Convergent Plate Boundaries”), as a result of the differing eruption styles associated with each. Axial volcanic ridges (AVRs), sometimes called neo-volcanic ridges, have been recognized at many slow-spreading Mid-Atlantic Ridge (MAR) spreading segments (e.g., Ballard and Van Andel, 1977; Karson et al., 1987; Smith and Cann, 1992; Parson et al., 1993; Sempere et al., 1993; Lawson et al., 1996; Bideau et al., 1998; Gracia et al., 1998; Navin et al., 1998; Briais et al., 2000; Peirce and Sinha, 2008; Searle et al., 2010) and some ultraslow-spreading segments elsewhere (Mendel et al., 2003)....
