GEOFF NORRIS is Director of the Palynology Laboratory and
a professor in the Department of Geology. Geoff is broadly interested
in all aspects of palynology, particularly as it relates to solution
of stratigraphic problems. He has a particular interest in
Mesozoic-Cenozoic palynology and the integration of information
from all available taxa marine and terrestrial. He has published
extensively on embryophyte spores and pollen, dinoflagellates, and
fungal palynomorphs, and believes that the successful application
of palynology to stratigraphy must rest on a firm, high resolution,
taxonomic base.
Geoff has recently completed a monograph on spores, pollen, and
dinoflagellates from Paleocene-Pliocene deltaic and inner shelf
sequences in the Beaufort-Mackenzie Basin, NWT. This has allowed
integration of sedimentological and faunal data into a robust
chronostratigraphic framework capable of extension across major
facies boundaries, and capable of rigorous application to
sequence stratigraphic models. He has extended this to other
Cenozoic basins in the eastern and western Canadian Arctic
and is hoping to contribute to the puzzling diversity changes
and evolution-extinction patterns - and lack thereof - of high
latitude floras.
His long-term interest in high-level taxonomy and phylogenetic
relationships of dinoflagellates cysts initially started with
W.A.S. Sarjeant in the early 1960's has culminated in a joint
publication with several co-authors of a classification which
appears to satisfactorily integrate existing knowledge of the
cysts and thecae of living and fossil dinoflagellates. Much of
the credit for bringing this work to completion rests with Rob
Fensome who actively pursued this research while a post-doctoral
fellow in the Toronto Palynology Laboratory and formerly with
Bill Sarjeant, University of Saskatchewan. Rob Fensome and
Geoff Norris were also invited to prepare summary of Cretaceous
dinoflagellates and spores and pollen for the DNAG volume on the
Canadian craton which appeared recently.
Geoff's earlier interests in the non-marine Cretaceous of the
Moose River Basin, James Bay Lowland, Ontario was recently
augmented by the completion of a doctoral thesis by Pierre
Zippi. He proved that spores and pollen could be used to
accurately date the main phase of sedimentation which occupied
a relatively brief period of time in the mid-Cretaceous. Further,
Pierre showed that the lacustrine environments were populated by
distinctive non-marine dinoflagellates and zygnematacean
cysts, representing some of the earliest records of these freshwater
algae. Comparable cysts in recent and sub-recent lake sediments
appear to offer the potential for tracking pH and Eh changes
associated with global change phenomena.
He has just completed a paper with Oyuang Shu (a Visiting Scientist
from the Nanjing Institute of Palaeontology, PRC) on Early Triassic
spore-pollen assemblages from northwest China. This is important
because the Dalongkou site in the Junggar Basin, Xinjiang is a
potential candidate for a global continental Permian-Triassic
boundary reference section.
Although most of the work done in our laboratory is focussed on
projects for which funding has been procured from national and
international sources, we do take the opportunity to welcome
undergraduates to investigate projects of their choosing which
can be researched using facilities in the Palynology Laboratory.
In this way, Lee Fortner wrote a B.Sc. thesis a couple of years
ago on Silurian acritarchs of the Rochester Shale of the Niagara
Escarpment. Lee has recently been revising for publication the
taxonomy and biostratigraphy of this work and has been collaborating
with Prof. H. Brett to place it in a sequence stratigraphic framework.
MARTIN J. HEAD is an independent consulting palynologist
as well as a research associate, sessional lecturer, and graduate
faculty member in the Department of Geology. His current research
interests are in the biostratigraphy, paleoecology, and taxonomy
of Upper Cretaceous and Cenozoic dinoflagellates. He is a veteran
of two ODP cruises (Legs 105 and 144) and is developing a
magnetostratigraphically-constrained Neogene dinoflagellate
biostratigraphy for the North Atlantic based on DSDP and ODP
cores. This work has been supported by the Palynology Industrial
Consortium comprising Amoco, Phillips, Unocal, Elf-Aquitaine,
Norsk Hydro, and Statoil. Research has shown that many dinoflagellate
and acritarch events are synchronous over large areas of the North
Atlantic. This suggests exciting possibilities for refining the
biostratigraphy of shelf and deltaic sequences where mineralized
microfossil zonations are sometimes difficult to apply, and for
the precise dating of high-latitude sites where other microfossils
are sparse or absent.
Along with his work on deep-sea deposits, Martin has been examining
neritic assemblages from classic Pliocene onshore sections in
northwestern Europe including the Royal Society borehole at
Ludham, the Chillesford Church beds, the Coralline Crag (all
eastern England), the St. Erth Beds (southwestern England),
and the Bosc d'Aubigny deposits (France). These studies are
helping to establish the superiority of dinoflagellates for
Plio-Pleistocene paleoclimatic reconstruction in Northwestern
Europe a field traditionally dominated by spore-pollen and
foraminiferal studies.
Martin is also studying the taxonomy and morphology of Cenozoic
dinoflagellates, with emphasis on cyst wall ultrastructure. This
character is best explored with a finely-tuned SEM and so is
often neglected in dinoflagellate taxonomy. The payoff is not
entirely esoteric. Recent taxonomic work has enhanced the
paleoecological and biostratigraphic utility of several
frequently confused species of the important Cenozoic genera
Habibacysta, Tectatodinium, Bitectatodinium, and
Filisphaera.
When Martin is not doing palynology or teaching, he can be
found at his computer working on the CAP finances and membership
files, editing the AASP Newsletter, or updating the AASP
Web site.
LAURENT DE VERTEUIL is a post-doctoral fellow in the
Department, having recently gained his PhD from the University
Toronto. As an undergraduate he visited the Calvert Cliffs in
Maryland and became fascinated with the exquisitely preserved
dinocysts he found there. The Chesapeake material provided the
basis for his dissertation, fieldwork for which was partially
funded by an AASP Student Scholarship. Laurent's research tries
to balance his theoretical interest in dinocyst morphology and
taxonomy, with a pragmatic approach to allostratigraphic basin
analysis. For example, he completed an original evaluation and
synthesis of published cyst terminology and applied the results
in describing stratigraphically useful new taxa. He developed a
ten part Miocene zonation for the coastal plain formations and
used it to delineate the subsurface allostratigraphy in
Virginia, Delaware and New Jersey. His dinocyst stratigraphy of
the Salisbury Embayment and adjacent Baltimore Canyon Trough
represents the state-of-the-art in Miocene chronostratigraphic
correlation for these basins. These taxonomic and stratigraphic
studies formed the core of his thesis, which he defended in
January. The results are presented in two papers that will
appear together next year in a Micropaleontology Special
Publication.
Following a summer stint at Exxon Production Research Company,
where he demonstrated that the zonation developed onshore in
Maryland could be applied to industry and COST wells off New
Jersey, Laurent was accepted to sail as palynologist on the
ODP New Jersey Sea Level cruise (Leg 150, summer 1993). With
calcareous dissolution affecting most of the Neogene sections
recovered from the New Jersey continental slope, the shipboard
dinocyst stratigraphy provided a solid correlation framework
between all the Leg 150 sites. These data, plus later shore-based
work, still provide the only sure Neogene correlations between
the continental slope and complimentary drilling in the New
Jersey Coastal Plain (ODP Leg 150X).
Three onshore boreholes in New Jersey (at Cape May, Atlantic City
and Island Beach), plus the Leg 150 sites on the continental slope
and rise, form part of the ongoing New Jersey Transect Project,
whose aim is to document the Oligocene to Recent record of sea-level
change and sequence architecture on this margin. A dip-parallel
series of shelf sites, that will be drilled in 1997, will complete
the transect. Laurent is the dinocyst stratigrapher for the New
Jersey Transect Project and in addition to his key responsibility
for erecting the Neogene chronostratigraphic framework for the
project, he is actively helping to delineate and interpret
stratigraphic sequences.
Samples from New Jersey Transect sites provide some material
for a related project that is being funded by a consortium of
five oil industry majors. The Integrated Neogene Geochronology
And Sequence Stratigraphy Project is coordinated from Woods Hole
Oceanographic Institution by William Berggren, and is beginning
work on integrating the next generation Neogene timescale with
well-constrained sequence records from basins with high-resolution
seismic and biostratigraphic data sets, and well-studied continuous
cores. As a post-doc with this project, Laurent is responsible
for the dinocyst horizons and palynofacies, and is working with
Marie-Pierre Aubry (calc. nannos.), William Berggren (planktonic
forams.), Anne Boersma and Mimi Katz (benthic forams.), and
Kenneth Miller (strontium isotopes).
In August, at the SEPM Congress in Florida, Laurent summarized
his results from the middle Atlantic Coastal Plain to an audience
composed mostly of Atlantic and Gulf coastal plain stratigraphers.
In the Neogene of Florida, where shallow water carbonate systems
are difficult to correlate, dinocysts have the potential to impact
the resolution of some long-standing basic questions in the regional
stratigraphy, including the timing of major oceanographic and
tectonic events in the history of the Florida Platform. Combining
dinocyst and strontium stratigraphy, and calcareous biostratigraphy
wherever available, is providing the key to inter-regional
chronostratigraphic correlation on the U.S. Atlantic margin.
Most recently, Laurent has begun to explore opportunities in low
latitude palynology, particularly in hydrocarbon-producing areas
such as Venezuela, and his native Trinidad. In July he attended
the joint Caribbean Geological Conference/Geological Society of
Trinidad and Tobago meeting in Port of Spain, and was encouraged
by the extent of biostratigraphic input into local
exploration and production. When asked to comment on future
directions in his career, Laurent managed only "Have scope,
will travel."
FLORIN NEUMANN is a PhD candidate with interests mainly in
dinocyst taxonomy, biostratigraphy, and palaeoecology. He worked
initially on Late Cretaceous cysts, but for his Ph.D. project,
which is supervised by M. J. Head and G. Norris, he has switched
to Cenozoic material. Florin earned the degree of Master of
Palynology from the University of Liège (Belgium), with a thesis
on the taxonomy of Campanian dinocysts from the Nevele borehole
(Western Flanders).
At the University of Toronto he studied dinocysts and pollen
from the Kanguk Formation on Banks Island (NWT). Preliminary
fission-track data from a tephra bed within Kanguk suggested
a latest Maastrichtian age for this formation, which was usually
considered to span the Campanian-Maastrichtian interval. Florin
proved conclusively that samples from below and above the tephra
bed were Late Campanian, and it was recognized that the fission-track
dating method used in this instance was in need of further refinement.
Florin is now working on a Ph.D. thesis on the distribution of
dinocysts in Pliocene deposits in areas adjacent to the Panama
isthmus, based chiefly on DSDP/ODP samples. He is developing a
dinocyst biostratigraphy for the area, and test-ing whether the
palaeobiogeography of Pliocene cyst-producing dinoflagellates
reflects the impact of a classical vicariant event, namely the
emergence of the Panama isthmus at approximately 3.5 Ma. Part
of this work was included in a presentation at the Fourth Canadian
Palaeontology Conference (1994), which received the best student
paper award.
Florin has been recently selected as shipboard palynologist for
ODP Leg 165 (Caribbean Ocean History and K/T Boundary Event).
Drilling at the five sites proposed for this leg will address
two major themes, the nature of the K/T boundary, and the
influence of tropical seas on global ocean history and climate
evolution. Objectives range from the study of ejecta mechanisms
of the Chicxulub impact event to the examination of effects of
the late Neogene closing of low-latitude oceanic gateways.
Florin has been a recipient of the prestigious University of Toronto
Connaught Research Fund Scholarship; in 1995 he was awarded the
American Association of Stratigraphic Palynologists Student Scholarship.
