Chromites separated from the upper mantle or lower crustal portions of 18 ophiolites ranging
in age from 900 Ma to 50 Ma are examined for Re-Os isotopic systematics. The ophiolites …

The timing and genesis of the major Ni–Cu–Co sulfide deposit in the **angshan intrusion
have been studied based on newly obtained in-situ U–Pb, Hf and Re–Os isotopic analyses …

New Os isotope and highly siderophile element (HSE) abundance data, in combination with
lithophile trace element and Sm–Nd, Lu–Hf, and Hf–W isotope data, are reported for …
