Autor: P.J. Aruscavage, Norma Rait, David Gottfried, Albert J. Froelich
Publikováno v: Journal of Geochemical Exploration. 37:75-89
The York Haven diabase sheet displays clear-cut evidence of fractionation of Pd and Pt during differentiation of a high-Ti (about 1.1%) quartz-normative tholeiitic magma (York Haven type). At York Haven the sheet is about 750 m thick. It is character
