NMS March 20th regular meeting:
Examples and applications from the Newark Basin, the Calvert Cliffs, and the Italian Apennines
Dr. Frank J. Pazzaglia
Our March 2019 meeting will be held Wednesday the 20th in room 116 (smaller auditorium) Earth & Engineering Sciences Building (EESB) on the west side of the Penn State campus in State College, PA. Maps are available on our web site.
6:45 to 7:45 p.m.: Social hour, special refreshments
7:45 to 8:00 p.m.: Announcements, questions, answers
about 8:00 p.m.: featured program
The event has free admission, free parking, and free refreshments, and is open to all; parents/guardians must provide supervision of minors. Bring your friends and share an interesting evening!
The Newark basin in Pennsylvania and New Jersey, the Calvert Cliffs of Maryland, and the Po foreland in northern Italy represent three different kinds of basins where cyclostratigraphy allows for the construction of novel age models in the basin sediments that can be utilized for the interpretation of diverse tectonic and climatic forcings. Cyclostratigraphy is predicated on the climate-sensitivity of the sedimentary record in a wide array of depositional environments, arising from the direct observation of distinct, repetitive patterns or cycles in lithostratigraphic or geochemical characteristics. Many cycles have been shown to have periodicities similar to those predicted by orbitally-driven climate changes when analyzed using spectral analysis. Growing recognition of signal shredding as well as sampling biases, incorrect data smoothing, tuning, and red noise models commonly applied during spectral analysis have justifiably questioned the veracity of some orbitally-driven interpretations; however there are a plethora of studies that demonstrate robust cyclostratigraphic records and interpretations when there is an appropriate age model anchored by numeric ages and correct statistical analysis of tuned data. Rock magnetic cyclostratigraphy measures variations in concentration, particle size, and mineralogy of ferromagnetic (magnetite, titanomagnetite, hematite, and Fe-sulfides such as greigite) and paramagnetic (Fe-rich silicates and diamagnetic quartz and carbonate) minerals in sediment or sedimentary rock. The sampling and measurements are quick and inexpensive so data can be collected at high resolution to document high frequency cycles. With the exception of diagenetic Fe-sulfides common in marine sediments, the variations in ferromagnetic and paramagnetic concentration and particle size in clastic-sink environments is linked back to the availability of these minerals recruited from the source basin, presumably as they are liberated from rocks by weathering. As a result, the ferromagnetic and paramagnetic concentration and particle size in sediments is a proxy for the efficacy of sediment recruitment in the source and delivery to the sink, a metric that clearly varies with both exogenic and autogenic drivers of surficial processes. In this way, rock-magnetic based cyclostratigraphy offers a superior way to see processes in the source through the lens of the stratigraphic record in the sink. The magnetic minerals are a kind of tracer, with memory of their genesis in the source.
DRIVING DIRECTIONS and PARKING for Earth & Engineering Sciences Building meetings on the Penn State campus (NOT Minerals Junior Ed. Day): After 5:00 p.m. and on weekends, free parking is available immediately across the street from the building. From North Atherton St. (Business Rt. 322) between College Avenue and Park Avenue, turn west (toward the golf course) off North Atherton at the traffic signal marked "White Course Drive." Go past the parking attendant's booth, follow the curve to the left, then turn right into the parking lot before reaching the stop sign. The building entrance is a little beyond the center of the lot, at the crosswalk. Enter the building, then go all the way across the lobby for our social hour & meeting room. We have a simple map at http://www.nittanymineral.org/EESBmap.jpg. For official campus maps see http://www.geog.psu.edu/print-campus-maps .
NMS has in stock T-shirts in Galapagos blue, Texas orange (both shown here) and royal blue.
