- Project:
- Analysis of a Unique Progressive Metamorphic
Sequence
-
- Project description:
- Since 1977, structural and metamorphic geologists
from the ETH have been carrying out mapping projects in the Himalayas
of NE Pakistan and Ladakh following on the traditions of Himalayan
field studies initiated by its pioneers Prof. Dr. A. Heim (e.g.,
Heim and Gansser, 1939) and particularly Prof. Dr. A. Gansser
(Gansser, 1964). The aim of these recent works in Pakistan and
India have been to study, in detail, (1) the geometry of the
tectonic units around the great bend of the NW Himalaya, the
Hazara-Kashmir syntaxis; (2) the tectonic evolution of the Higher
Himalaya in Pakistan and (3) the along strike evolution of the
Indus Suture Zone in Pakistan. These ETH (upto 1992) and SNSF
(upto May, 1997) financed projects are virtually all concluded
and have led to a model of formation of the syntaxial region.
The model consists of an anti-clockwise change in the tectonic
shortening direction which can be related, on a regional and
plate scale, to the initial impingement and subsequent rotation
of the Indian Plate during the continent-continent collision.
An unexpected discovery in the course of these projects was the
finding of a unique progressive (unmetamorphosed to eclogite
facies) metamorphic sequence. The Tethyan Himalayan sediments
can be traced from India into Pakistan, firstly as a distinctive
unmetamorphosed unit and then as a metamorphosed cover to the
Higher Himalayan Basement. This unit, therefore, provides a unique
metamorphic record of the Himalayan continental collision and
can be used to map compositional changes related to progressive
metamorphism. Unmetamorphosed sediments of Carboniferous to Triassic
age in the Zanskar region of India are intercalated with Permian
volcanic rocks of the Panjal Traps. This sequence is now proved
to correlate with the equivalent high-pressure metasediments
and metavolcanics from Kaghan Valley in Pakistan. Through fieldwork
(in Pakistan and India) and laboratory studies (at the University
of Cambridge (UK), Massachusetts Institute of Technology (USA),
Tokyo Institute of Technology (Japan), University of California,
Santa Barbara (USA), Stanford University (USA) and the University
of Maine (USA)), I intend to study and collaborate with numerous
renowned scientists on the progressive metamorphism of the Panjal
Traps, specialising in its structural, metamorphic, geochronological
and tectonic evolution through the Himalayan continental collision.The
Panjal Traps clearly offer a unique insight into the time-progressive
evolution of a continent-continent collision. Using detailed
mapping techniques, I will systematically analyse the structural,
metamorphic and geochronological variations along strike of the
Panjal Traps. Laboratory analysis will include relating deformation,
geochronology and metamorphism. My aim is to synthesise the results
of these various techniques in order to be able to propose a
model of the evolution of the India/Asia collision zone, as seen
from the progressive metamorphism of basic, carbonate and other
sedimentary lithologies. The uniqueness of the Panjal Traps suggests
that such data will be of fundamental importance to other orogenic
belts, and metamorphism in general. This work will maintain links
with the Institutes at the Department of Earth Sciences at the
ETH: the Institute of Geology, Institute for Isotope Geology
and Mineral Resources and the Institute of Mineralogy and Petrology.
