Analysis of samples from San Andreas Fault borehole suggest creeping sections lubricated by clays.

Rather impressive for a 5.0: 50 ft-wide chasm opened by quake-triggered landslide in Quebec
Italy puts seismology in the dock. [Wow. Who knew it was a crime to fail to predict the unpredictable?]
(from @NatureNews)


Finally, a discussion of [Gulf of Mexico] oil spill in relation to inevitable risks associated with deep sea drilling
Depressing statistic from David Archer: our CO2 ems = 5k #oilspills/day, every day
(via @morphosaurus, @KHayhoe)
BBC interview with rig worker claiming faulty BOP control pod was shut off, not fixed in weeks before explosion
Richard Heinberg on #oilspill’s Worst Case Scenario. [subsurface damage could stymy relief well? Scary.]
(from @postcarbon)
Not convinced solution to iron fertilisation not working is to order a bigger experiment.
(via geoengpolicy)
Bacteria could boost CO2 sequestration? [Ironically, end quote about need for massive scaling up relevant to all CCS]


Nice review in Science of mechanisms driving last deglaciation. Large, unstable N Hemisphere ice sheets key threshold
Ouch. Spherules cited as evidence for Younger Dryas impact ‘fossilized balls of fungus, charcoal, fecal pellets’
[I have previously blogged about this debate here and here]
New weather and climate podcast – the Barometer
(via @dr_andy_russell, @TheBarometerPod)
Conveyor model for ocean circulation a bit too simplistic to be useful?
[Although I would skip the appallingly opaque press release and read a far superior discussion by @olelog]

Was Venus once habitable? [Seems there was once lots of water, but lost to space q early]
(via @earthmagazine)
New Clues Suggest Wet Era on Early Mars Was Global [Hydrated clay minerals now seen in N & S hemispheres]
(via @physorg_com)

General Geology

New way to detect mantle plumes: diffraction effects instead of travel times. Doubt it will convince ‘no plumes’ gang.
Great blog post by @clasticdetritus)t: Rapid canyon formation and uniformitarianism.
At the edge of the intrusion [Awesome field photo of intrusive contact]
Infrastructure and Mineral Wealth [Good point: finding & extracting are two entirely different things]
(via @Geoblogfeed)
A way to think about channel patterns.
(via @drjerque)

Interesting Miscellaney

Facebook & twitter mobile updates have contributed to decline of traffic to Blogger & WordPress blogs
(via @suehutton)
[Seems more like a maturation to me; makes sense that people who just want to post links, photos, status updates are moving to tools better suited to these tasks.]

    Perhaps another Leda clay landslip? I don’t know if there’s any up that way, but there are deposits of the stuff all over the Ottawa Valley, and down in the Southern Townships, and every so often several acres of land slump into the nearest ravine. There was a whole family killed near Drummondville quite recently by one of these events.
