2015 10 13 – Dr. James discusses the trace fossil, Rusophycus, while explaining biological activity along the ocean platform margin during GEOL301 field course.  

(Nikon D300 w 17-35 f2.8 @26mm f4 1/200^th I.S.O. 500) 

2015 10 14 – Queen’s University students examine submarine turbidite Bouma sequences along the St. Lawrence River at I’Islet, Quebec.  A Bouma sequence is a package of sediment with distinct characteristics based on particle settling velocity and flow.

2015 10 15 – Queen’s University students examine an Ordovician debrite (underwater debris flow) near the Lauzon Cemetery in Quebec City. These debrite flows contain clasts of material from shallower water, providing insight into the platform fauna assemblage.

2015 10 16 – Dr. James explains magnesium fluctuations in ocean chemistry and how it is directly linked to mid-oceanic rifting. The class is standing on material directly from the mantle, which is magnesium rich due to hydrothermal alterations. The mantle is at a depth of approximately 2,900 kilometers; the deepest whole drilled to date is approximately 12 kilometers deep.

2015 10 17 – Dr. Godin points out the various features associated with pillow lava. This outcrop located near Mont Adstock, Quebec is an excellent example of Paleozoic pillow lava produced at the mid-oceanic ridge of the Iapetus Ocean.
