Schedule (will be updated as we move on during the quarter)

- Monday, January 9

James Jackson Continental and oceanic lithosphere: structure and rheology. Suggested reading: Jackson, J. Mountain roots and the survival of cratons. Astronomy & Geophysics}, v46, 233-236, 2005

(This is a short, relatively jargon-free, popular summary of a particular point of view that has been changing rapidly. It is at least relatively up-to-date.)

- Monday, January 16

Jean-Philippe Avouac, Introduction to Central Asia tectonics.

Aron Meltzner: Continental tectonics: localized or distributed deformation?

Reading: Flesch, L. M., Haines, A. J., and Holt, W. E., 2001, Dynamics of the India-Eurasia collision zone: J. Geophys. Res., v. 106, p. 16435-16460

- Monday, January 23

John Suppe and Ravi Kanda will discuss the mechanics of critical-taper wedge and discuss examples from the Tarim basin

Reading: Suppe, 2006, Absolute fault and crustal strength from wedge mechanics, draft ms.

- Monday, January 30

John Suppe and Jean-Philippe Avouac will discuss folding and thrusting along the southern and northern piemont of the Tian Shan.

Reading: Molnar, P., et al., 1994, Quaternary Climate-Change and the Formation of River Terraces across Growing Anticlines on the North Flank of the Tien-Shan, China: Journal of Geology, v. 102, p. 583-602.

Addition background reading (pdfs available on JPA ftp site):

Avouac, J. P., et al., 1993, Active Thrusting and Folding Along the Northern Tien-Shan and Late Cenozoic Rotation of the Tarim Relative to Dzungaria and Kazakhstan: Journal of Geophysical Research-Solid Earth, v. 98, p. 6755-6804.

Poisson, B., and Avouac, J. P., 2004, Holocene hydrological changes inferred from alluvial stream entrenchment in North Tian Shan (Northwestern China): Journal of Geology, v. 112, p. 231-249.

-Monday, February 6

Steven Kidder will review how the Critical wedge model relate to geological observations.

Reading: Brandon, 2004, short chapter in van der Pluijm and Marshak entitled "The Cascadia Subduction Wedge: the role of accretion, uplift, and erosion" It is a short paper introducing the basics of critical wedge theory. More elaborated papers by Barr, Dhalen et al are available on my ftp.

I will then introduce the fold and thrust belt of northern Tian Shan.

As a related reading I suggest Molnar, P., et al., 1994, Quaternary Climate-Change and the Formation of River Terraces across Growing Anticlines on the North Flank of the Tien-Shan, China: Journal of Geology, v. 102, p. 583-602. ).

-Monday, February 13

Willy Amidon will be leading the discussion on the Kyrgyz Tianshan based on the paper by Thompson et al. 2002. Papers are on presentation page.
