Harrisburg Area Geological Society

HAGS

The purpose of the Harrisburg Area Geological Society (HAGS) is to stimulate geologic thought, advance and disseminate geologic knowledge, and provide fellowship amongst area individuals interested in earth sciences. Monthly meetings (at GTS Technologies at 441 Friendship Road in Harrisburg) present a realm of geologic topics, ranging from tectonics, coal, carbonate groundwater geochemistry, Martian geomorphology, engineering geophysics, nuclear waste repositories, and ore mineralogy. Field trips allowed members to visit geologic sites within and beyond Pennsylvania. All events are open to the public and free unless otherwise stated. Meetings are at GTS Technologies, 441 Friendship Rd, Harrisburg, PA 17111. They occur at 6:30 PM on the second Thursday of the month, except summer months.

Amber, copal, and plant exudates: the sticky stuff that many plants ooze

Presented by:

Dr. Jorge Santiago-Blay, Department of Paleobiology, National Museum of Natural History 

Abstract: Many plants produce organic materials – called exudates – out their surfaces. Through carbon-13 solid state nuclear magnetic resonance spectroscopy, it has been discovered that there are three major categories of plant exudates – resins, gums, and phenolics.  Fossilized resins are known as amber, the oldest of which has been dated to the Carboniferous period.  Resins provide an insight to scientists with respect to paleoclimates, and allow for the study of ancient animal species which become entombed in the substance.  In this talk, the speaker will explain the basics of plant exudates, their classification, cultural uses, chemistry, and how they are studied.

Speaker Bio:  Dr. Jorge A. Santiago-Blay completed his BS and MS in Biology, with emphasis in zoology, at the University of Puerto Rico. In 1990, he completed his MA in Botany and PhD in Entomology at the University of California at Berkeley. His professional career has had three simultaneous facets: research, teaching, and administration.  Since 1998, he has pursued his research interests in arthropods and plants as a Research Associate in the Department of Paleobiology at the National Museum of Natural History (Washington, DC). Also, he is a faculty member at different universities, including serving as a Lecturer at The Johns Hopkins University. In addition, he serves as Editor-in-Chief of Life: The Excitement of Biology (https://blaypublishers.com).
