CEES Seminar

[Natalie Campbell]

Post 1:
subject line: CEES Seminar

The CEES Seminar Series presents:

*Dr. Laura Webb, *University of Vermont, Department of Geography and

Geosciences


*New insights on polyphase deformation in the New England Appalachians *


Reverse faults along the western front of the Berkshire and Green Mountains
place very old basement rocks over younger Cambrian–Ordovician rocks,
cutting across earlier structures

formed during the Taconic Orogeny. Microstructures and Argon–argon
(40Ar/39Ar) dating show
that these faults were reactivated multiple times beginning about 420
million years ago and continued for at least 70 million years.
40Ar/39Ar dating
that was once thought to indicate slow cooling following the Taconic
Orogeny, may in fact date the reactivation of these faults.  This talk will
explore these new findings and how they relate to recent and ongoing
results from seismic imaging of the lithospheric and mantle structure in
the northern New England Appalachians.




*Friday March 27**  3:30**pm. *
*Hudson 106*
*Reception prior to the talk at 3:00*
