TimelineSupercontinent Timeline. The Caledonian orogeny took place after the breakup of Rodinia at about 750 million years ago (Ma) when three of the continental blocks that would ultimately form part of Pangea assembled. These blocks were (i) Laurentia, which corresponds to present-day North America, Greenland, and Scotland; (ii) Baltica, corresponding to present day-Scandinavia; and (iii) Avalonia, corresponding to southern Britain and parts of mainland northern Europe.

GPS-measured subsidence in Louisiana, including the Mississippi Delta (the region south of 30.5° N latitude). The southern part of the delta (south of 29.5° N latitude) is subsiding at an average rate of 6 mm/yr. Considering the current rate of sea level rise (the global average is about 3.3 mm/yr – see Figure 5), the southern delta is probably facing rates of relative sea level rise of at least 9 mm/yr.

A low pressure band, as a proxy for the suction of a subducting slab, initiates convergence (negative divergence or the blue band on the “divergence” sphere) but then vanishes and a new pressure zone occurs perpendicular to the last one, and the sequence is repeated twice more. For the Earth-like case with a cool surface, damaged, weak zones accumulate, as shown in the “viscosity” sphere, and strike-slip bands of vorticity develop; in the end there is a convergence zone driven by the final low-pressure proxy-slab, with a passive divergence zone and strike-slip margins, as shown in Figure 7. https://speakingofgeoscience.org/wp-content/uploads/2016/05/fig7-br2014.jpgDBSlides4HH.pptxFigure 7: A calculation of pressure-driven flow in a thin 2-D horizontal-layer model of the lithosphere, where the pressure low is akin to a single subduction zone (see schematic frame). The rheology of the layer is governed by the grain evolution, damage and pinning model of Bercovici and Ricard [2012 , 2013 ]. In this case the low pressure zone P is imposed and then rotated about a vertical axis by 90 degrees three times (with roughly 10Myrs dimensional time between rotations to develop damaged weak zones) as an idealization of intermittent and chaotic subduction during the early Archean. The bands of damage induced by the pressure low from a previous orientation are long-lived, inherited and amplified by the lithospheric flow of the next orientation, resulting in localized but passive bands of strike-slip vorticity  and positive divergence S (red and yellow contours; convergence with S < 0 , indicated by blue contours, is actively driven by the pressure low). Thus a complete plate arises with a contiguous weak plate boundary (indicated by viscosity  ) while only being driven by subduction, which is the final state shown (with final dimensionless time indicated on the P frame). Dimensionless extrema for contours or vectors are indicated below each frame, save P which is always between 0 and 1. This model is proposed to explain the emergence of plate tectonics in the Archean, from proto-subduction 4Ga to global tectonics by ~3Ga. Adapted from Bercovici and Ricard [2014], which also gives further details of the calculation. https://speakingofgeoscience.org/wp-content/uploads/2016/05/fig-6.jpgFig.-6https://speakingofgeoscience.org/wp-content/uploads/2016/05/fig5-mylonite.jpgMyloniteOlivine.jpgFigure 5: A wonderful example of a peridotitic or mantle mylonite, from Lars Hansen’s website https://lnhansen.wordpress.com and from work done for Hansen et al.

A) Seafloor spreading indicator of ophiolites. Age distribution of ophiolites from Dilek (2003) for those up to 1040 Ma, plus minor Paleoproterozoic ophiolites (e.g., 1.95 Ga Jormua ophiolite, Finland; Peltonen & Kontinen, 2004). B: Subduction zone indicators are all distinctive metamorphic rocks; blueschists and glaucophane-bearing eclogites, coesite- or diamond-bearing ultrahigh-pressure (UHP) metamorphic rocks, lawsonite-bearing metamorphic rocks, and jadeitites. Ages of blueschists are from Tsujimori and Ernst (2014); of UHP metamorphic belts from Liou et al. (2014); of lawsonite-bearing metamorphic rocks from Tsujimori & Ernst (2014); of jadeitites from Harlow et al. (2015). The third plot (Phan. Age Zircons Dist.) looks at zircons regardless of host sediment age and only plots the detrital zircons that are age-dated at 542 Ma or less in age. [one caveat - because detrital zircons follow the principle of inclusions - we should not see any zircons younger than the host rock age, so it should follow that the host sediment age in this plot is also 542 Ma or less. This likely is mostly the case - though the host sediment age was always estimated from sources other than the DZ's in the host sediment and hence are independent ages).https://speakingofgeoscience.org/wp-content/uploads/2016/03/fig4.jpgFig4Fig. 4: A) Histogram of U-Pb zircon ages for three kinds of rocks: ancient sediments (green), modern river sediments (blue), and orogenic granitoids (red). Black line shows summary histogram for all three rock types (N = 37,830). Modified after Condie and Aster (2009). B) ≤5% discordant-filtered pooled U-Pb age distributions for detrital sedimentary rocks from Voice et al. (2011) (N=100,445). Notice that the same 5 peaks are seen in both datasets. The <500 Ma part of the two curves are quite different.https://speakingofgeoscience.org/wp-content/uploads/2016/03/fig3.jpgFig3Fig. 3. What drives plate motions. A) All of the possible driving forces of Plate Tectonics, from Forsyth and Uyeda (1975). There are eight possible forces driving and resisting plate motions. FDF = asthenospheric drag; FCD = continental drag; FRP = ridge push; FSP = slab pull; FSR = slab resistance; FCR = colliding resistance; FSU = trench suction; FTF = transform fault resistance. If mantle convection currents make plates move, that would correspond to high FDF. B) Evidence that convinced Forsyth and Uyeda (1975) that slab pull force (FSP) was the most important. The fastest-moving plates are those that are attached to a downgoing plate. The white parts of bars correspond to margins on opposite sides of the plate; in these cases, the opposing FSP cancel each other out. In addition to the dominant slab-pull force, Forsyth and Uyeda (1975) also recognized that ridge push (FRP) and drag on the base of the continental lithosphere (FCD) also contributed minor proportions of the total plate-driving force.https://speakingofgeoscience.org/wp-content/uploads/2016/03/fig2.jpgFig2Fig. 2: What does not drive plate motions. The simple-minded idea that mantle convection currents drive plate motions, as depicted in this cartoon, is not just oversimplified, it is fundamentally WRONGhttps://speakingofgeoscience.org/wp-content/uploads/2016/03/fig-1.jpgFig. 1Fig. 1: Geologic timescale and suggestions for the onset time of plate tectonics, from Korenaga 2013).

On our all day hike to the western margin of the Tuolumne Intrusive Complex, I snuck off at lunch and enjoyed an unparalleled view of the Sierran crest without a person in sight. Right there is one of the best reasons to become a geologist.https://speakingofgeoscience.org/wp-content/uploads/2012/10/10-lunch_tree1.jpg10 lunch_treeCalifornia, on the whole, is a very dry place – especially so this year. One of our lunchstops might have been greener (and swimmable) at other times of the year, but when we got there, it seemed that this tree was the only respite from the sun. Might explain why the whole group could be seen hiding under its branches (one of the few times people weren’t drawn to the rocks).https://speakingofgeoscience.org/wp-content/uploads/2012/10/09-climbers_elcap1.jpg09 Climbers_elcapEl Capitan was one of the most stunning views of the trips. This was not only because of the beauty of such a shear face of granite, but also the climbers clinging to the side of the cliff. I’m not one for heights, but seeing these people, like tiny speaks, on the side of El Capitan made me pleased to have both feet firmly planted on the ground.https://speakingofgeoscience.org/wp-content/uploads/2012/10/08-conglomerate1.jpg08 ConglomerateWe saw more than just magmatic features. The immense strain that many of the wallrocks and pendants felt were evident in the rocks as well. This outcrop is a Jurassic conglomerate that is on the western margin of the Tuolumne Intrusive Suite – part of the host rock for the intrusive. On one surface, the pebbles look relatively normal (surface with lens cap), but slice through the rocks like this outcrop has nicely provided, as you can see how stretched out and smeared these pebbles has become. These rocks have felt a lot of stress during their lifetime, and the stretching of these pebbles is part of the way it has been accommodated.https://speakingofgeoscience.org/wp-content/uploads/2012/10/07-bergantz_outcrop2.jpg07 Bergantz_outcrophttps://speakingofgeoscience.org/wp-content/uploads/2012/10/07-bergantz_outcrop1.jpg07 Bergantz_outcropAt first glance, you might think that this is an outcrop of sedimentary rocks, with crossbeds and channels. However, this is all granite (and their close allies) within the Tuolumne Intrusive Complex. George Bergantz (University of Washington) provides the scale for this magnificent outcrop that shows separate of light and dark minerals (mostly feldspar and quartz juxtaposed with amphibole). If you look closely, you’ll see some megacrysts in the outcrop, all aligned as if they were flowing in the magmatic pile – and they very well could be – which begs the question: what was the state of the magmatic system when this was active? Every time I see this, I notice something new that makes me scratch my head.https://speakingofgeoscience.org/wp-content/uploads/2012/10/06-megacryst_zoning1.jpg06 Megacryst_zoningUntil you’ve been to the Tuolumne Intrusive Complex, it might be are to believe that you can find single crystals of feldspar that are upwards of 10 cm across – but sure enough, in the Cathedral Peak granite, you find these giant megacrysts. In a glacially polished surface like the one in the image, you get to look at cross-sections through the crystals and you can see the zoning of the crystals with the naked eye (labeled above). How exactly the magma was able to grow such large crystals (and the ultimate source of the megacrysts) is still up for debate.https://speakingofgeoscience.org/wp-content/uploads/2012/10/05-mixing_crenulate1.jpg05 Mixing_crenulateBeing a petrologist interested in how magmas interact, some of the outcrops during the Forum were amazing. This example of magma mixing/mingling from the Fine Gold Intrusive Suite shows a dark, mafic magma interacting with a light, felsic magma. Some of the interactions clearly suggest the mafic magma was cool enough to form angular blocks (to the right of the hammer). However, other parts for very delicate crenulate (wavy) margins to the mafic blocks, suggesting that the magma was still molten during their interaction (labeled in image). Looking at these outcrops, you can begin to envision lobes of mafic magma flowing into a pile of mushy, felsic magma beneath a volcanic edifice.https://speakingofgeoscience.org/wp-content/uploads/2012/10/04-weibe_talking1.jpg04 Weibe_talkingYou don’t need to be looking at a whole mountain range to think about the processes that formed the Sierra Nevada either. At this outcrop in the Fine Gold Intrusive Suite, Bob Wiebe (UC Davis) – an expert on interpreting magmatic fabrics – talks about what he seems in these mixing and mingled magmas to a group of onlookers from the Forum. These interactions are what helps make Field Forums such a great experience.https://speakingofgeoscience.org/wp-content/uploads/2012/10/03-saddlebag1.jpg03 SaddleBagWhen thinking about a geologic province as big as the Sierra Nevada, sometimes you need to really look at the big picture. With Saddlebag Lake in the background, Forum leader Scott Patterson regales the group with tales of deformation within the Sierra Nevada batholith and the metamorphic pendants that are found intermingled with the plutons. Trying to parse out the source of these slivers of metamorphic rocks is tricky – some may have travelled hundreds of kilometers (not to mention tens of kilometers up and down) before ending up in the final location. The clues to this journey are all recorded in the rocks themselves.2016-03-22T16:08:41+00:00monthlyhttps://speakingofgeoscience.org/2013/06/14/what-will-happen-to-references/https://speakingofgeoscience.org/wp-content/uploads/2013/06/figure3-blog.jpgFigure3-blogFigure 3.
