Abstract:
The 27 mantle xenoliths have been collected in eastern China. The content of CaO, Au and PGE of 21 peridotite xenoliths were determined. The relationship of gold with CaO for the 27-peridotite xenoliths suggests that the gold content of the xenoliths relates to partial melting degree of mantle. The peridotite xenoliths that their chondrite-normalized PGE patterns are smooth have higher golden contents. The peridotite xenoliths that their chondrite-normalized normalized PGE patterns are decline have lower gold content.
