ACCEPTED MANUSCRIPT ABSTRACT
16
The island of Jamaica forms the northern extent of the Nicaraguan Rise, an elongate linear tectonic
17
feature stretching as far as Honduras and Nicaragua to the south. Uplift and subaerial exposure of
18
Jamaica during the Neogene has made the island rare within the Caribbean region, as it is the only area
19
where rocks of the Nicaraguan Rise are exposed on land. Biostratigraphic dating and
20
palaeoenvironmental interpretations using larger benthic foraminifera, supplemented by planktonic
21
foraminifera, nannopalaeontology and palynology of outcrop, well and corehole samples has enabled
22
the creation of a regional relative sea-level curve through identification of several depositional
23
sequences. This study recognises ten unconformity-bounded transgressive-regressive sequences which
24
record a complete cycle of relative sea-level rise and fall. Sequences are recognised in the Early to
25
‘Middle’ Cretaceous (EKTR1), Coniacian-Santonian (STR1), Campanian (CTR1), Maastrichtian
26
(MTR1-2), Paleocene-Early Eocene (PETR1), Eocene (YTR1-3) and Late Eocene-Oligocene (WTR1).
27
These transgressive-regressive cycles represent second to fourth order sequences, although most tie
28
with globally recognised third order sequences. Comparisons of the Jamaican relative sea-level curve
29
with other published global mean sea-level curves show that local tectonics exerts a strong control on
30
the deposition of sedimentary sequences in Jamaica. Large unconformities (duration >1 Ma) are
31
related to significant regional tectonic events, with minor overprint of a global eustatic signal, while
32
smaller unconformities (duration 1 Ma), quantified through biostratigraphic analyses, are related to
924
significant regional tectonic events, with minor overprint of a global eustatic signal, while smaller
925
unconformities (duration
