Van Tuyl: Cenozoic Flat-slab Subduction Processes and The Tectonic Development of Southern Alaska

Dr Ken Ridgway of Purdue University and, previously, Chevron, spoke on a unique subduction zone in south-central Alaska. Here, in a situation similar to that at the Ontong Java Trench in the southwestern Pacific, a large oceanic plateau is subducting under the continent. Because the majority of oceanic crust is relatively thin and dense, it readily slides under continental crust, which is thicker and more buoyant. When a thick deposit of undersea lavas reaches a subduction zone, however, it causes problems, since such volcanic provinces are different from normal oceanic crust. Such a situation is called “flat slab subduction” because of the tendency of the subducting crust to go under the continent at a much shallower angle than normal.

UC&T/UCA: Tunnelling in the Nation’s Capitol

The Clean Rivers Project is a multi-billion-dollar endeavour, projected to run until 2025, to stop sewer overflow during storms from going into the three rivers that flow through the D.C. area, which is the current destination for sewer overflow for a third of the region. It will also help mitigate extreme flooding from even relatively minor storm events. The slowest-moving of the rivers concerned, the Anacostia, is being tackled first. Four major CSO tunnels are being constructed, at a cost of $3.5 billion, to tie into and divert storm overflow from the city’s sewers.

Scientific discoveries this week: 3/3/14

Jack Hills, Australia – A piece of zircon discovered in an outcrop on a sheep farm in Western Australia has been discovered to been discovered to be the oldest unchanging piece of earth discovered, at an age of 4.4 billion years. John Valley, the geoscience professor from the University of Wisconsin who led the research, claims that this could imply that the planet was capable of sustaining earth 4.3 billion years ago where the earliest fossils are 3.4 billion years old, implying life-sustaining temperatures earlier than previously thought.
