Berriasian to Aptian Dinoflagellate Cysts from the Galicia Margin, Offshore Spain, Sites 638 and 639, ODP Leg 103

Abstract

The dinoflagellate cyst assemblages in 42 samples collected from Sites 638 and 639 were analyzed. All samples from Site 639 are barren; relatively poor assemblages occur in samples from Site 638. The distribution of 61 dinoflagellate cyst taxa identified in samples from Holes 638B and 638C are tabulated.The assemblages from Site 638 are comparable to those of Tethyian stratotypes and from neighboring areas, which permits age determinations and correlations between Holes 638B and 638C. The interval from Cores 103-638C-14R to 103-638C-1R is late Berriasian through Valanginian in age. In Hole 638B, the interval from Core 103-638B-43R to Sec tion 103-638B-23R-2 is dated as early Valanginian through middle Barremian. Sections 103-638B-21R-2 and 103-638B-21R-1 are late Aptian in age.Taxonomic remarks are made about some species; a new dinoflagellate cyst Heterosphaeridiuml galiciae is de scribed.
