Tour of California turbidites

With three new grad students recently accepted into the CoRE research group at Colorado School of Mines, I wanted to take them into the field to scope out thesis projects and just to show them some classic turbidite locales in California. Here is a very quick overview of that trip, and some pertinent references in case …

Climbing-ripple successions in turbidite systems: depositional environments, sedimentation rates and accumulation times

Wow, that is a title right there! The third and final paper (PDF) of my thesis is finally published - I submitted this paper in 2010, and it was published online in the fall of 2011. Now however, it is finally out in print, and it feels real now. It was my most 'academic' project, …

New Zealand turbidite field trip – (final) Day 6: Scoured submarine lobe deposits

So, we took a day to drive across from the Taranaki basin to the East Coast basin, the forearc side of the Coromandel arc of the north island of New Zealand.  I wont try to elaborate on the Neogene tectonics of New Zealand - there have been multiple episodes of shortening, extension, strike slip, and …

New Zealand turbidite field trip – Day 4: Mass transport deposits

Holy cow.  It just keeps getting better.  I can honestly say that my mind was blown today.  We saw some mass transport deposits (MTDs) that are truly seismic in scale!  Maybe not as big as the Storegga slide, but pretty dang big.  For a nice paper on MTDs, go here.  Since there is a student …

New Zealand turbidite field trip – Day 2-3: Submarine lobe deposits

Wow, these rocks are fantastic! The last two days we have been looking at submarine lobes exposed along the Taranaki coast. Lobes are areas downstream of submarine channels where the gradient decreases (i.e. becomes quasi-flat) and turbidity currents deposit sand in an oblate shape emanating from the channel. For a great paper on lobes, see …
