Announcement:

In the event that US 101 remains closed through Tuesday, January 16th, there is a chance our planned speaker may not be able to join us. 

In any case, we will still hold our meeting and dinner, as it is too late to make cancellations with our venue and caterer. We still encourage you to come and share a delicious meal with your fellow CGS members and hear about our upcoming plans. 

Thank you for your continued participation through this difficult season!

Please Join CGS on Tuesday January 16th, 2018

Dr. Matthew Jackson, Professor in the Department of Earth Science at UC Santa Barbara, will give his talk titled:

Talk Abstract:

The fate of subducted tectonic plates and the survival of primordial reservoirs in the Earth’s deep interior

          The Earth’s deep interior is a dynamic environment that convects and stirs on billion-year timescales.  Plate tectonics injects altered oceanic crust, sediments, and depleted mantle lithosphere into the mantle, permitting communication between surface and deep reservoirs in the Earth. The fate of the subducted material is not known, but it constitutes a significant reservoir in the Earth’s mantle that may be sampled by buoyantly upwelling mantle plumes that source volcanic hotspots. While prospecting for geochemical signatures of ancient subducted oceanic lithosphere in hotspot lavas, fingerprints of surviving relics of the earliest history have been identified. Mantle domains sampled by these hotspot lavas date to the earliest Hadean, prior to the formation of the moon, and provide insights into the evolution of the planet.
