WebA calcium metasomatized rock in which the primary igneous composition and texture have been destroyed to an extent that the nature of the protolith is uncertain. If the nature of the protolith can be discerned but calcium metasomatism is obvious, the rock was described as rodingitized. Selvages WebAlteration intensity in the gabbroic rocks, recovered in the upper 150m of Hole CM1A, varies from fresh (5%) to highly altered (95%) with an overall average alteration of approximately 30%. In both holes, alteration of the gabbros is highest near hydrothermal veins and in rodingitized domains within the crust-mantle-transition sequences. bcc safeguarding training
