Volcanic history of Mount Sidley, a major alkaline volcano in Marie Byrd Land, Antarctica

first_imgMount Sidley is a complex, polygenetic stratovolcano composed primarily of phonolitic and trachytic lavas and subordinate pyroclastic lithologies at the southern extremity of the Executive Committee Range, a linear chain of volcanoes in central Marie Byrd Land, Antarctica. Detailed field investigation coupled with 14 high precision 40Ar/39Ar age determinations reveal a 1.5 million year life span between 5.7 and 4.2 Ma in which three major phonolitic central vent edifices (Byrd, Weiss and Sidley volcanoes) and their calderas were developed (5.7–4.8 Ma). This was followed (4.6–4.5 Ma) by the eruption of trachytic magmas from multiple vent localities further south, and then by small volume benmoreite-mugearite lavas and tephras around 4.4–4.3 Ma at the southern end of Mount Sidley. The final phase of activity was the eruption of basanite cones at approximately 4.2 Ma. The southward migration of volcanic activity was accompanied by distinct changes in magma composition and is best explained by the sequential release of magmas stored within an intricate system of conduits and chambers in the crust by tectonically driven (magma assisted?) fracture propagation. The style of volcanic migration at Mount Sidley is emulated on a larger scale by other volcanoes in the Executive Committee Range, in which progressive southward displacement of volcanic activity corresponds with significant petrological variations between major centers.last_img read more

WanderLove in Chesapeake

first_imgSouth Norfolk Jordan Bridge Most people are surprised to find such a unique piece of engineering tucked away in a corner of Chesapeake, making The South Norfolk Jordan Bridge one of Chesapeake’s true hidden gems. The two-mile round-trip walking path is a popular spot for locals to get out and about, and when you take in gorgeous panoramic views of the Elizabeth River from a 167-feet high bridge, you can literally see why.

One of the best ways to celebrate changing seasons is to sample local produce. But, stay with us for a second, what if instead of local produce, you sampled local beer? Big Ugly Brewing and The Garage Brewery are Chesapeake breweries with unique, local and seasonal beers on tap. It’s not just their “gotta try” beverages like Big Ugly’s S’mores Brown Ale or The Garage’s Sunkissed Strawberry Blonde that makes both of these spots worth the visit. They also present opportunities to celebrate local, open spaces that allow the community to thrive and come together while still being safe and mindful of others.   Whether it’s a weeklong vacation or a quick day trip, the fall season in Virginia evokes a desire in all of us to just hop in the car and explore the amazing locations this state has to offer.

What better way to wrap up your WanderLove experience than by stopping by Chesapeake’s LOVEworks sign at Courtyard Square Park.
