Distribution of Au and Pd in basalts and diabases in DSDP/ODP Hole 504B
Listed in PANGAEA
Au contents have been determined in 77 samples of basalts and sheeted diabase dikes.
Description
Pd has been evaluated in 39 of the samples. The mean amount of Au is 3 parts per billion (ppb), fluctuating from 0.4 to 10 ppb.
Au contents appear to be independent in type and intensity of alteration as well as with depth sub-bottom, although in the lower part of Hole 504B, 1900-2000 mbsf, Au contents are markedly decreased (mean: 1.1 ppb) and show a distinct correlation with a decrease in Zn contents. Pd contents vary from 2 to 360 ppb (mean: 37 ppb) Pd is higher in basalts (53.7 ppb) and lower in diabase dikes (30 ppb), especially in moderately or strongly altered ones (12.5 ppb).
