January Talk: Thrust Faults as a Mechanism for Attenuation in the Steep Limbs of Laramide Folds in Colorado by Dr. Vince Matthews
THRUST FAULTS AS A MECHANISM FOR ATTENUATION IN THE STEEP LIMBS OF LARAMIDE FOLDS IN COLORADO By Dr. Vince Matthews, Retired Colorado State Geologist and Director of the Colorado Geological Survey ABSTRACT Key exposures of several Laramide, basementcored folds in Colorado provide views of an ordered architecture of faults in their forelimbs. The faults provide an important mechanism for thinning and extending the strata in the steep limbs as displacement on the master, basement fault increases. One location demonstrates…

February Talk: Structural inheritance for the Laramide, Central Montana Uplift: A wrench-fault tectonic model related to Proterozoic Orgogenesis in the Foreland of the North American Cordillera By Jeff Bader
Structural inheritance for the Laramide, Central Montana Uplift: A wrench-fault tectonic model related to Proterozoic Orgogenesis in the Foreland of the North American Cordillera By Mr. Jeffrey W. Bader, North Dakota Geological Survey ABSTRACT The Central Montana uplift of eastern Montana lies adjacent to the Northern Rocky Mountains on the western edge of the Northern Great Plains Physiographic Province, and just north of the Laramide belt of the Central Rockies. The origins of this deformed region have received little…

May Talk: Seeing the Forest for the Trees Across North America’s Cordilleran Foreland Megasequence by Erik Hulm, TeoGeo Consulting
Seeing the Forest for the Trees Across North America’s Cordilleran Foreland Megasequence by Mr. Erik Hulm, TeoGeo Consulting ABSTRACT: The North American Cordilleran foreland basin once formed a contiguous succession of sedimentary rocks that extended from the Gulf of Mexico to the Arctic Ocean. Much has been published on the structural character and evolution of the Cordilleran but little on the full breadth of the foreland sedimentary fill and hydrocarbon endowment. This is largely due to post-Cretaceous structural modification and…

September Meeting – Using the rock record to explain anomalous seismic velocities in modern subduction zones – Carolyn Tewksbury-Christle (FLC)
Cost is $20 - Scroll down to pay online or RSVP to pay at door Happy Hour from 5:30 to 6:30 on the Sitter Family Hall 3rd floor deck overlooking the city of Durango with drinks and heavy appetizers. Talk starts at 6:30 pm in SFH 710 (the classroom with the wall-o-screens). Abstract: Subduction zones play a major role in large-scale Earth processes, including seismic and volcanic hazards and mass and volatile recycling. The interface between the overriding and downgoing…
