Chamba Syncline: fabric development 25/03—06/04/2012
Prograde fabric development in metasediments of the Chamba syncline in the NW Himalaya: a neat example of the changes seen with structural depth and increasing metamorphic grade from the first slaty cleavage in the lower chlorite zone to garnet-zone schist with a complex fabric developed from a crenulation cleavage.
First, five large-field images taken at the same scale, to show macroscopic changes in style with grade. Then, details of microstructure in sequence of increasing structural depth and metamorphic grade.
These photos formed the basis for an examination question in 2012. The samples were collected by J.D. Walker (D.Phil 1998).
