Spinel phases of the White Hills peridotite, St. Anthony complex, Newfoundland: part 1 occurrence and chemistry.
This peridotite is an interlayered sequence of spinel lherzolite and harzburgite; subordinate dunite occurs in layers and in 'dykes' and lenses. Pyroxenite and gabbroic dykes occur both crosscutting and occasionally parallel to the tectonite fabric; chromitite lenses or seams are associate...
