Abstract

BOOK REVIEW | Diversity of Hydrothermal Systems on Slow Spreading Ocean Ridges

Highlights

The global mid-ocean ridge system spreads over a spectrum of rates, and oceanic crust formed at slow and ultraslow spreading ridges (< 40 mm yr–1) differs from the more “ideal” layered structure formed at faster spreading ridges
Hydrothermal activity at slow spreading ridges can range from mafic- to ultramafic-hosted systems that have different rock and fluid compositions; both of them can occur over a range of temperatures
The chapters do not seem to be arranged in any systematic order, other than the Introduction and the short chapter by Rona, which gives a historical perspective of exploration for hydrothermal activity and documents discoveries on the MidAtlantic Ridge

Summary

Introduction

The global mid-ocean ridge system spreads over a spectrum of rates, and oceanic crust formed at slow and ultraslow spreading ridges (< 40 mm yr–1) differs from the more “ideal” layered structure formed at faster spreading ridges. Review of Diversity of Hydrothermal Systems on Slow Spreading Ocean Ridges, edited by P.A. Rona, C.W. Devey, J. Hydrothermal activity at slow spreading ridges can range from mafic- to ultramafic-hosted systems that have different rock and fluid compositions; both of them can occur over a range of temperatures.
