Wednesday, April 2 with Dr. Marian Lupulescu
The Fascinating Science of Pegmatite Rocks – Storehouse of Gems, Industrial and Strategic Minerals

Pegmatites are basically igneous rocks with composition similar to granites, gabbros, syenites, but characterized by exceedingly coarse, sometimes gigantic, crystal size. The focal point of research by mineralogists and petrologists comes from the pegmatites's intriguing texture and anatomy, and diversity of the rare, strategic, industrial, and spectacular gem mineral species they contain. Dr. Marian Lupulescu, Curator of Geology, will present a general overview with a case study of the New York pegmatite rocks.


Appalachian Mountains


Wednesday, April 9 with Dr. Chuck Ver Straeten
Back When the Appalachians Were Young, Rugged, and Tall
Three times in the geologic past small to large continents collided with eastern North America, forming what today are the deeply eroded Appalachian Mountains. But New York's sedimentary rocks preserve a record of times when Appalachians were as high as today's Andes Mountains. Join Dr. Chuck Ver Straeten and "read" what New York's rocks tell about ancient Appalachian uplift and erosion, volcanism and more around 400 million years ago, during the Devonian Period.


Land Forms


Wednesday, April 16 with Dr. Andrew Kozlowski
Landforms and Time: A Closer Look at Geologic Processes and Time
How long did it take for that hill, knoll or that favorite glen you like to hike to form? And how did it form? These features, known as landforms consist of a wide range of physiographic features that collectively form the surface of the Earth. New York States landscape is diverse and provides stunning examples of multitude geologic processes from the last glaciation and much older processes. Join Dr. Andrew Kozlowski, Museum Scientist and Quaternary Geologist as he provides a general overview of landforms and techniques used by scientists to understand rates of erosion and deposition and how they shape the surface of our planet.



Carbon Sequestration


Wednesday, April 30 with Museum Geologist, Brian Slater
Carbon Sequestration in New York State:  A Decade of Research
Most scientists agree that greenhouse gasses such as carbon dioxide (CO2) are a major contributor to global climate change. The geologic sequestration of carbon dioxide has emerged as one of the leading methods for reducing the emission of greenhouse gases. For the past 10 years New York State Museum geologists have worked on several projects that investigate the potential for carbon sequestration in New York State. Join museum geologist Brian Slater as he discusses some of these studies and how each presents its own unique challenges.
