The Bouma sequence and turbidite deposits

For a while now, the most popular page on my site has been this one, a photo of a Halloween pumpkin I carved to look like the Bouma sequence.  It is the most popular because people are looking for information about the Bouma sequence, so it is time to do a real post on the …

New Zealand turbidite field trip – day 1

Today we went to a nice outcrop along the west Taranaki coast to look at Miocene turbidites.  These deep-marine sandstones were deposited in a retro-arc setting during the mid to late Miocene - more on that in another post.  The Taranaki basin is also a very productive basin in terms of hydrocarbons, with more than …

Geo-pumpkin: a perfect Bouma sequence turbidite!

UPDATE, Nov 7, 2012 - see this post for a broader overview of turbidite deposits. I came home today and had to join the fun, and my entry is my favorite geological feature, the turbidite.  Arnold Bouma described it, Roger Walker and Don Lowe interpreted it, and I carved it into a pumpkin.  Check out …
