Slimline magma chambers
Article Abstract:
The magma chambers which lie below the mid-ocean ridges and which yield up the oceanic crust may be made up of narrow, hot crystal-melt mush zones beneath very thin lenses of pure melt. J.M. Sinton and R.S. Detrick relied on observational, geophysical, geochemical and computational data to propose a refinement of the traditional view that magma chambers are mostly liquid reservoirs varying in form. In reality, the chambers may be variegated structures marked by a hot transition zone.

Frozen magma lenses below the oceanic crust
Article Abstract:
The images of groups of Moho transition zone reflection events that resulted from the analysis of approximately 1,500 km of multichannel seismic data collected across the intermediate-spreading-rate Juan de Fuca ridge are presented. The observations suggest that gabbro lenses and melt accumulations embedded within dunite are the most probable cause for the observed reflectivity.

Portrait of a magma chamber
Article Abstract:
Issues are presented concerning the spreading centres which form around 20 square kilometers of ocean crust each year. The nature of the spreading centres of the mid-ocean-ridge systems are discussed.
