ich spore-pollen assemblage. The sample is<br />
from the base of approximately 32 in of medium-<br />
to coarse-grained sandstone with<br />
streaks of brown-gray clay and occasional<br />
carbonaccous streaks. Forty-nine species of<br />
pollen and spores in 36 genera are documented.<br />
On the basis of the occurrences of<br />
Aequitriradites plicatus, Appendicisporites<br />
jansonii, Contignisporites multimuratus, Cyclusphaera<br />
sp. A, Muricingulisporis annulatus,<br />
and Ornamentifera echinata, the age of the<br />
sample is considered to be Early Cretaceous<br />
(Hauterivian). The absence of marine palynomorphs<br />
indicates that the horizon sampled was<br />
deposited in a non-marine setting, close to<br />
araucarian and fern vegetation. The spore genus<br />
Sphagnites Cookson 1953 is emended,<br />
and the species Sphagnum antiquasporites<br />
Wilson & Webster 1946 is transferred to<br />
Sphagnites.<br />

Late Jurassic and Cretaceous palynomorph<br />
assemblages were recovered from the Macomia,<br />
Pemba, and Mifume formations front the<br />
onshore Rovuma Basin. northern Mozambique.<br />
These assemblages provide new evidence for<br />
in Aptian-Albian age for the Macomia Formation<br />
and the Upper member of Pemba Formation,<br />
and confirm that these two stratigraphic<br />
units are coeval and laterally continuous. The<br />
lower member of the Pemba Formation contains<br />
Kimmeridgian-Tithonian palynomorphs,<br />
thus documenting for the first time the existence<br />
of Upper Jurassic strata north of Nacala<br />
in the onshore Rovuma Basin. The rich and<br />
diverse dinoflagellate cyst assemblage recovered<br />
from the Mifume Formation is of late<br />
Campanian age. This indicates an early Late<br />
Cretaceous hiatus between the sandstones of<br />
Pemba Formation, and the marls of the overlying<br />
Mifume Formation. The hiatus corresponds<br />
to a break in sedimentation prior to a<br />
rapid. global marine transgression, recognised<br />
in the Rovuma and Mozambique basins, during<br />
the middle Campanian, associated with the<br />
onset of Gondwana fragmentation. Earlier,<br />
Late Jurassic faulting produced local halfgrabens<br />
filled with continental debris, for example<br />
the N'Gapa Formation of northern Mozambique.<br />

粉 研 究 = Upper Cretaceous to Neogene palynology<br />
of the Melut Basin, Southeast Sudan.<br />
( 英 文 ). Eisawi A; Schrank E. Palynology,<br />
2008, 32(): 101-129<br />
The palynology of the Upper Cretaceous to<br />
Neogene non-marine succession in the Melut<br />
Basin, southeast Sudan was investigated. The<br />
palynomorphsare overwhelmingly of terrestrial<br />
origin, but rare brackish water dinoflagellate<br />
cysts and scolecodonts were encountered<br />
from the Lower Miocene and Oligocene-<br />
Miocene. Mangrove pollen, which is common<br />
in coeval West African coastal basins, is rare<br />
and inconsistent. Examples are Spinizonocolpites<br />
(Nypa) from the Campanian-<br />
Maastrichtian to Eocene and Rhizophoraceae<br />
(Zonocostites romonae) from the Neogene.<br />
Based on the stratigraphic distribution Of Selected<br />
pollen and Spores from four exploration<br />
wells, eight informal palynozones from the<br />
Campanian to the Neogene are proposed. The<br />
zones. in stratigraphically ascending order, are<br />
as follows: Assemblage Zone 1, Campanian<br />
(lower Melut Formation) Assemblage Zone 11,<br />
(middle Melut Formation): Assemblage Zone<br />
III, Maastrichtian (upper Melut Formation)<br />
Assemblage Zone IV, Palcocene (Yale Formation)<br />
Assemblage Zone V, Eocene (upper Yale<br />
and Adar formations); Assemblage Zone VI,<br />
Oligocene-Early Miocene (Jimidi and lower<br />
Miadol formations): Assemblage Zone VII,<br />
Early Miocene (uppermost Miadol and lowermost<br />
Daga formations)-. and Assemblage<br />
Zone VIII, Late Miocene-Pliocene (Daga<br />
Formation). The ages are based on stratigraphic<br />
positions and a series of first downhole<br />
appearances of key species Such as Foveotricolpites<br />
cf. giganteus (Zone I), Auriculiidites<br />
reticulatus (Zone II), Ariadnaesporites<br />
spinosus (Zone III), Periretisyncolpites giganteus<br />
(Zone IV), Retistephanocolpites williamsii<br />
(Zone V), Cricotriporites camerounensis<br />
(Zone VI), Peifotricolpites digitatus (Zone<br />
VII), and Peregrinipollis nigericus (Zone<br />
VIII).<br />
