Pennsylvanian
conodont elements
One of the most striking features of Precambrian through Phanerozoic
deep-water carbonates is a bedding style characterized by thin,
even-bedded, fine-grained limestone layers rhythmically interbedded
with marl or shale layers ("rhythmites"). Individual
limestone-marl (or shale) couplets can be traced for hundreds of meters
to many kilometers. The origin of the rhythmites has been
attributed to primary depositional alternations between carbonate-rich
(limestone) and carbonate-poor (marl or shale) facies and are termed
"depositional rhythmites" (e.g., Elrick et al., 1991; Elrick and
Hinnov, 1996). Alternatively, the interlayering has been
attributed to differential diagenesis and unmixing of a relatively
homogeneous precursor and are called "diagenetic rhythmites" (Ricken,
1986; Munnecke and Samtleben, 1996; Westphal et al., 2000).
The origin and duration of at least 12 different
Paleozoic depositional rhythmites successions has been investigated,
and in each case, the individual limestone-marl/shale couplets
represent <3000 years of time and the main process influencing the
deposition of alternating lithologies was controlled by paleoclimatic
changes which controlled 1) the amount of eolian and/or fluvial
sediment input into the offshore basins, 2) storm-generated or dilute
density currents delivering fine detrital carbonate and sponge spicules
to the offshore basins, and/or 3) wind-driven upwelling currents which
supplied dissolved silica to benthic sponge populations. (various past
NSF and PRF funding).
CYCLOSTRATIGRAPHY AND SEQUENCE
STRATIGRAPHY OF PROTEROZOIC, PALEOZOIC,
MESOZOIC, AND TERTIARY CARBONATES OF THE WESTERN U.S., MEXICO, AND
SPAIN
Our research group has been studying the cyclostratigraphy and sequence
stratigraphpy of various Proterozoic, Paleozoic, Mesozoic, and Tertiary
marine systems across the western U.S., Mexico, and Spain. This
type of work forms the basis for all subsequent paleoceanographic,
paleclimatologic, or geochemical studies. (Work funded by various past
NSF funding)
MILANKOVITCH-SCALE
CYCLICITY RECORDED IN THE MAGNETIC SIGNATURE OF CARBONATE ROCKS
(collaboration with Dave Anastasio and Ken Kodama, Lehigh University)
Rock magnetic
variations record cyclicity within lithologically homogeneous, outer
shelf lime mudstones of the Lower Cretaceous San Angel Limestone,
northeastern Mexico. Variations in ferromagnetic mineral
concentrations, as measured by anhysteretic remanent magnetization
(ARM), occur at frequencies consistent with Milankovitch orbital
rhythms. Magnetic mineral composition, grain-size distributions, and
grain shapes from digested samples are congruent with far-traveled
atmospheric dust. Prevailing winds and the proximity of the Cretaceous
basin to an African eolian source support the encoding of orbitally
modulated changes in wind intensity or source area aridity within the
San Angel Limestone. ARM measurements offer great potential to
calibrate the pace of depositional processes in carbonate-dominated
sedimentary deposits and to investigate high-frequency orbitally driven
climate change in widely distributed basinal strata throughout geologic
time (from Latta et al., 2006, Geology, Latta et al., submitted
to P-3) (NSF funding).
INVESTIGATING
THE USE OF APATITIC CONODONTS FOR U-Pb AGE DATING OF PALEOZOIC-TRIASSIC
MARINE SEDIMENTARY DEPOSITS (collaboration with Steve Getty, James
Ebert, Yemane Asmerom,
Victor Polyak)
Conodonts are
phosphatic microfossils common in many marine deposits of Cambrian
through Permian age and they provide some of the highest resolution
biostratigraphic age control available for rocks of this
age. U-Pb isotopic age dates from conodonts would provide
much needed absolute age control for many stratigraphic successions
which contain conodonts. We are testing the utility of conodonts
for U-Pb isotopic age dating using limestone samples from the Middle
Devonian Onondaga Formation (Cherry Valley, New York) and compared the
U-Pb age to that of the well dated Tioga “B” bentonite which
immediately overlies the sampled limestone layer. Zircons and
monazites from this bentonite have been dated by Tucker et al. (1998)
and Roden et al. (1990) as 391 ±1.8 Ma and 390 ± 0.5 Ma,
respectively. Approximately 6 kg of skeletal limestone was
collected and 70-120 individual conodont elements were analyzed for
each data point using standard isotopic dilution techniques.
Preliminary results indicate that the conodont ages overlap with the
bentonite age; the conodonts are dated as 406 ± 18 Ma.
These promising results from the Middle Devonian conodonts may
partially be a function of the fact that the conodonts were partially
silicified which limited the affects of burial diagenesis.
PALEOCEANOGRAPHIC CHANGE RECORDED
IN THE C-ISOTOPE STRATIGRAPHY AND SEQUENCE STRATIGRAPHY OF
MID-CRETACEOUS (CENOMANIAN-TURONIAN) MARINE CARBONATES OF SOUTHERN
MEXICO (collaboration with Roberto
Molina-Garza, UNAM)
The Albian-Turonian Morelos Formation (>800 m) was deposited along a
westward-deepening carbonate platform in southern Mexico (Guerrero
state) and is composed of subtidal through peritidal skeletal
wackestone-grainstones. It is abruptly overlain by the Turonian Mexcala
Formation (1000 m), which is composed of pelagic carbonates and
siliciclastic turbidites. The higher sediment accumulation rates of
platform carbonates (vs. pelagic rates) permits previously unattainable
high-resolution data on the Cenomanian-Turonian (C-T) boundary and the
relationship between nearshore physical/biologic processes (sea-level
and benthic biota changes) and geochemical processes (anoxia, stable
isotope, TOC, trace elements). In addition, these C-T boundary deposits
provide a much-needed record of Pacific/Caribbean ocean influences;
much of our present knowledge comes from C-T sections in the
proto-Atlantic or Western Interior seaway.
Only minor evidence of high-frequency sea-level
changes is observed (meter-scale upward shallowing cycles) and
systematic facies changes related to M.y.-scale sea-level change
(depositional sequences) are absent except for abrupt deepening just
above the C-T boundary. Three sections show similar C-isotope trends
over a 60-100 m-thick interval (~0.5 m sampling interval): relatively
uniform values positive values (over ~30 m), two abrupt 2-3‰ negative
shifts (<10 m), an abrupt 5-6‰ positive shift (<3 m), plateau of
uniformly higher values (~10 m), a gradual 2-6‰ decrease (~10 m),
followed by relatively uniform values (10<sup>+</sup>m).
TOC values are low (<0.2 wt%) and show no obvious stratigraphic
trends. Trace metal abundance anomalies (Co, Ni, Cr, Pb, Zn, Cs, W, Sb,
Mo, Ag, Se) across the Mexican C-T boundary are explained by magma
outgassing and hydrothermal exchange with seawater during volcanic
activity that built the Caribbean oceanic plateau at ~90-94 My,
supporting a possible link between the global C-T isotope excursion
(OAE-2) and large oceanic plateau formation.
