Strontium isotope stratigraphy for CRP-3, Victoria Land Basin, Antarctica
Lavelle, M.. 2001 Strontium isotope stratigraphy for CRP-3, Victoria Land Basin, Antarctica. Terra Antartica, 8 (4). 593-597.Full text not available from this repository.
Strontium isotope stratigraphy was used to date 5 discrete horizons within the CRP-3 drillhole. A single in situ modiolid bivalve fragment at 10.88 mbsf gives an age of 30.9 (±0.8) Ma for the associated sediment. The four remaining well preserved fragments recovered from 29.94-190.31 mbsf are within error of this age, indicating a high sedimentation rate and suggesting little time is missing in disconformities. The diagenetic alteration of carbonate macrofossils by continental fluids (and possibly seawater) is a common feature to 320 mbsf.
