“…Subordinate facies include non-marine lignite and palaeosols, and shallow-marine shellbeds. As for elsewhere in the Wanganui Basin, the succession of facies in the Nukumaru section can be resolved into depositional sequences following the sedimentary facies and shellbed approach developed by Abbott & Carter ( 1994), Naish & Kamp ( 1997), and Kondo et al (1998). These sequences were deposited on the basin margin during successive interglacial sea-level highs.…”

“…Shellbeds regarded as significant in a sequence stratigraphic context are classified following the scheme applied by Naish & Kamp (1997) after Kidwell (1991, fig. 15), and elaborated upon by Kondo et al (1998). Onlap, backlap, compound (a combination of onlap and backlap), and toplap shellbeds are recognised in the Nukumaruan stratotype, the characteristic features of which are summarised in the following.…”

Late Pliocene to Early Pleistocene (c. 2.08-1.63 Ma) strata exposed in coastal cliffs along Nukumaru and Ototoka beaches near Wanganui, between the top of the Nukumaru Limestone and the base of the Butlers Shell Conglomerate, comprise 11 depositional sequences of a total thickness of c. 86 m. The sequences consist predominantly of silicilclastic shoreline facies. Non-marine facies (including palaeosols), and a variety of shallow-marine shellbed facies, are also represented. Patterns in facies composition and sequence architecture reveal three sequence motifs (Maxwell, Nukumaru, and Birdgrove) that represent progressively increasing maximum palaeowater depths within a broadly basin-margin palaeogeographic setting. The sequence motif changes systematically up section and records a lower order tectonic influence on accommodation that has modulated the stacking patterns of individual sequences. Correlation of the sequences with oxygen isotope stages 77-57 is achieved using the basin-wide Ototoka tephra, and indicates that the sequences accumulated in response to obliquity driven (41 k.y. duration) glacio-eustatic sea-level oscillations. Correlation of the Nukumaru coast sequences with other sections along basin strike, and the global oxygen isotope record indicates that (i) 500 k.y. (δ 18 O stages MIS 56-34) is missing at the unconformity between the Nukumaruan and overlying Castlecliffian stratotypes on the Wanganui coast, and (ii) the Pliocene-Pleistocene boundary lies within sequence NC7 at the base of the Lower Maxwell Formation.

“…The black pebbles indicate coastal erosion during relative sea-level rise (Strasser 1984). The deposit would therefore be categorized as a transgressive lag (Kondo et al 1998) yet the shell destruction and encrustation commonly associated with such a deposit (Kidwell 1991) is lacking. Therefore, the coquina is interpreted as a complex composite storm accumulation formed during transgression, which possibly underwent repeated burial (Kidwell 1991;Meldahl 1993).…”

High-spired nerineoid gastropods are abundant in the tropical Kimmeridgian carbonate deposits of the Swiss Jura Mountains. Understanding the mode of life of this extinct group of gastropods is crucial for palaeoenvironmental reconstructions. The knowledge on their ecology is, however, limited by the near absence of comparable large high-spired gastropods in Recent carbonate systems. Large high-spired turritellid gastropods are, however, abundant in siliciclastic-dominated environments in the tropical Indian Ocean. In order to compare the Recent and fossil environments of these two morphologically similar groups, a Recent tidal Xat, where abundant turritellids occur, was studied in the National Park of Nopparat Thara in the district of Krabi, South Thailand. Ninety specimens of Turritella duplicata were measured and mapped, revealing zonations in population distribution, both parallel and perpendicular to the beach line. Attention was also paid to other faunal elements and sedimentary features. The thusgained information on the depositional environment was then compared to a section of shallow-water carbonate deposits from the Kimmeridgian of the Swiss Jura Mountains. These are characterised by the occurrence of tidal laminites, dinosaur tracks, beach deposits and nerineoid gastropods. Especially for one succession, the faunal composition and sedimentary structures in the fossil record show intriguing similarities to those found today on the Nopparat Thara tidal Xat, indicating that it formed in a comparable setting. It is therefore suggested that for some Kimmeridgian carbonate deposits, the Nopparat Thara tidal Xat, although dominantly siliciclastic, represents an environmental analogue.

“…Thus, the recognition of (1) vertically-stacked facies successions bounded by sharp erosion surfaces (sequence boundaries), and (2) the distinctive shellbeds and their associated stratal discontinuities, delineate the stratigraphic geometry of the sequences and allow systems tracts to be differentiated (e.g., sensu Vail 1987). Naish & Kamp (1997a) and Kondo et al (1998), after Kidwell (1991), have recognised onlap, backlap, downlap, and flooding surface shellbeds. These shellbeds are associated, respectively, with the transgressive surface of erosion (TSE), a local flooding surface, the downlap surface, and paracycle-bounding marine flooding surfaces.…”
