Early Eocene Radiolarian Fauna from the Sangdanlin, Southern Tibet: Constraints on the Timing of Initial India‐Asia Collision

“…Buryella tetradica first appeared approximately at the Early/Late Paleocene boundary at Site 208(mid NP4) (Hollis, 1997). Although only a maximum age limited could be determined for the top of RP5 (lower NP6), it was close to the minimum age limit provided by the FA of Bekoma campechensis in tropical and North Atlantic (Foreman 1973a;Nishimura 1987). (Nishimura, 1992).…”

“…P. s. striata first appeared in lower RP8 in the Mead Stream (Hollis, 1997). Buryella clinata had not been encountered in the Sangdanlin section, but elsewhere the top of the B. clinata zone (Foreman, 1973a;Nishimura, 1987) was marked by the evolutionary transition from P. s. exquisita to P. s. striata and the LA of Bekoma divaricata. In summary, the zone could roughly be compared with New Zealand radiolarian zone RP7 and RP8 (Hollis, 1997), which had been explained as an age of late Paleocene to early Eocene, containing the Paleocene/ Eocene boundary.…”

“…The Late Cretaceous radiolarian assemblage of the investigated section was compared with the radiolarian zonations presented by Forman (1975,1977), Pessagno (1976), Sanfilippo and Riedel (1985), O'Dogherty (1994), Vishnevskaya and DeWever (1998), Hollis and Kimura (2001). The Paleocene samples were main dated on the basis of Riedel and Sanfilippo (1970, 1971, 1978, Foreman (1973aForeman ( , 1973b, Sanfilippo and Riedel (1973), Nishimura (1987Nishimura ( , 1992, Nigrini (1998a, 1998b), Sanfilippo and Hull (1999); De Wever et al, (2001), Liu and Aitchison (2002), Hollis (1997Hollis ( , 2002.…”

Foraminiferal, radiolarian, and dinoflagellate biostratigraphy of Late Cretaceous to Middle Eocene pelagic sediments (Muzzle Group), Mead Stream, Marlborough, New Zealand

“…15-16) Mead Hill Formation consists mainly of fine-grained, light grey-green to tan, siliceous limestone with common dolomite and abundant chert as nodules, ribbon cherts, and massive beds. Webb (1966Webb ( , 1971 (Berggren et al 1985;Sanfilippo et al 1985;Nishimura 1987) follows Hornibrook et al (1989). Radiolarian zones RK9 and RP1-5 (indicated by asterisk) have been identified only in the New Zealand region and Hokkaido, Japan (Hollis 1993a).…”

“…Faunas from uppermost Mead Hill to the top of Amuri Limestone are diverse, but many of the primary Paleogene index species that form the basis of established zonations from low latitudes (Riedel & Sanfilippo 1978;Sanfilippo et al 1985) and the North Atlantic (Nishimura 1987(Nishimura , 1992 either are absent or occur only rarely and sporadically. Nevertheless, sufficient numbers of age-diagnostic taxa occur to make preliminary correlations with established zones (referred to as Zones RP6-RP13 herein).…”
