Introduction and the ophiolite modely to land-bound lay people the great depth of the oceans, the fundamental differences between continents and oceans, and the constant renewal of the ocean floor by seafloor spreading and subduction, when their concepts are bounded by a wrinkled sea surface viewed from the air. In the early nineteenth century such ideas lay beyond everyone’s grasp.

Oceanic peridotiteshat partial melting of garnet peridotite would lead to the production of a basaltic magma and a ‘barren’ or residual peridotite. This idea of a partial melting continuum [i.e. garnet peridotite (source)-dunite (residue)-basalt (partial melt)] gained wide acceptance and was fundamental in any consideration of upper mantle evolution.
