THE HIMALAYAN OROGEN: OBSERVATIONS, MODELS, AND FUTURE RESEARCH
DIRECTIONS
1. Introduction
The Himalaya is a classic example of orogenic systems created by continent-continent collision.
The youthfulness and spectacular exposure make it an ideal place for examining diverse geologic
processes associated with mountain building. Using its history as a guide to decipher the dynamics
of continental deformation and its interaction with global climatic change has motivated numerous
multi-disciplinary and multi-nation investigations in the past two decades in the region. Many
workers have also used the knowledge of the Himalaya to infer evolution of other orogenic
systems such as the Paleozoic Central Asian Orogenic System, the Proterozoic Trans-Hudson
orogeny in North America, the Caledonides in Greenland, the Canadian Cordillera of North
America, and the East African-Antarctic orogen in Antarctica and Africa. It is clear that one
cannot be a complete tectonician without deep understanding of the Himalayan geology. This is
perhaps the main reason that the Himalaya has attracted the best minds of Earth Sciences from all
over the world since the turn of the last century: Emil Argand, Arnold Heim, Augusto Gansser,
Chris Powell, Patrick LeFort, Claude Allegre, Peter Molnar, to name a few. Despite the intense
interests to Earth Science community, it has become increasingly daunting for a new student to
learn about its geology. This difficulty may be attributed to its long research history making its
literature nearly intractable, confusing terminology, and proliferation of tectonic and physical
models. The purpose of this class is (1) to provide a historical perspective on the Himalayan
research and to elucidate its broad implications for the modern studies of Earth Sciences, (2) to
use the Himalaya as an example to introduce modern research methods, analytical techniques,
current dynamic models for mountain building, and outstanding issues facing the next generation
of Earth scientists, and (3) to cultivate a dynamic learning atmosphere.
2. Class Schedule
Lectures will be given twice a week each lasting three hours with 15 minutes break in between.
Tentatively, the classes will be scheduled on Tuesday and Thursday.
3. Class Content
Week 1 (9/-9/19)
I. Introduction. (A) Basic Terminology: Himalayan Range, Himalayan Orogen, Himalayan
Tectonic System, Tibetan Plateau, and Himalayan-Tibetan Orogen. (B) Topography and geography
of the Himalaya. (C) Plate Boundary conditions for the development of the Himalayan Origin. (D)
Timing and mechanism of Neo-Tethyan closure.
II. Structural Framework of the Himalaya. (A) Major structures and lithologic units: definitions
and distributions. (B) Himalayan metamorphism and its relationships to tectonics. (C) Structural
transects of the western, central, and eastern Himalaya.
Week 2 (9/12-9/16)
I. Exhumation history of the Himalayan orogen and development of Himalayan foreland basin. (A)
Cooling history of the Himalaya. (B) Depositional history of the Himalayan foreland. (C) Isotopic
signature and detrital zircon ages of major Himalayan lithologic units. (D) Bengal and Indus fans.
II. Hypotheses for the Himalayan development: kinematic models (single vs. multiple thrusts.
wedge extrusion, simple shear, recumbent folding, and passive-roof faulting).
Week 3. (9/19 - 9/23)
I. Hypotheses for the Himalayan development: (A) Thermal models with prescribed kinematics
(steady-state models; time-dependent models: delamination model, hot-iron model,
frictional-heating model, accretion/erosion model). (B) Fully couple thermo-mechanical models.
II. Outstanding problems in the Himalayan research. (A) Interaction between tectonics and climate:
concepts, models, and observations (short- and long-term processes). (B) Plate boundary
conditions and response in continental deformation: what are the causes for development of
asymmetric drainage systems in the Himalayan and Indian subcontinent? (C) Mechanics of the
South Tibet Detachment Fault.
4. Audience
(1) Upper-division undergraduate students who have taken Structural Geology, college physics,
and multi-variable calculus.
(2) Graduate students in geology, geophysics, and geochemistry who have interests in mountain
building processes.
(3) Researchers who are interested in learning Himalayan geology outside China and current
development and debates on the formation and development of the Himalayan orogen.
5. Class format
1. Although the class is mainly based on lectures, I will also lead short discussions during
lectures. Students are strongly encouraged to ask questions and challenge lecture materials at all
levels.
2. The lectures will be given in English, but students can ask questions in Chinese. If needed,
the instructor will answer questions in Chinese as well.
