Journal ArticleDOI
Developing an inverted Barrovian sequence; insights from monazite petrochronology
Catherine Mottram,Clare J. Warren,Daniele Regis,Nick M.W. Roberts,Nigel Harris,Tom Argles,Randall R. Parrish +6 more
TL;DR: In this article, petrochronologic methods applied here constrain a complex temporal and thermal deformation history, and demonstrate that inverted metamorphic sequences can preserve a rich record of the duration of progressive ductile evolution of the thrust.
Journal ArticleDOI
Tectonic interleaving along the Main Central Thrust, Sikkim Himalaya
Catherine Mottram,Tom Argles,Nigel Harris,Randall R. Parrish,Randall R. Parrish,Matthew S.A. Horstwood,Clare J. Warren,S. Gupta +7 more
TL;DR: In this paper, structural analysis, whole-rock Nd isotopes, and U-Pb zircon geochronology reveal that the hanging wall of the Himalayan orogen is characterized by detrital Zircon peaks at c. 800-1000 Ma, 1500-1700 Ma and 2300-2500 Ma and an ϵ Nd(0) signature of −18.3 to −12.1.
Journal ArticleDOI
Using U-Th-Pb petrochronology to determine rates of ductile thrusting: Time windows into the Main Central Thrust, Sikkim Himalaya
Catherine Mottram,Catherine Mottram,Randall R. Parrish,Randall R. Parrish,Daniele Regis,Clare J. Warren,Tom Argles,Nigel Harris,Nick M.W. Roberts +8 more
TL;DR: In this paper, the authors used U-Th-Pb monazite ages, compositions, and metamorphic pressure-temperature determinations from rocks directly beneath the Main Central Thrust (MCT) to calculate the minimum rate of movement on a major ductile fault zone, the MCT, by a novel methodology.
Journal ArticleDOI
Deconvolving the pre-Himalayan Indian margin – tales of crustal growth and destruction
TL;DR: In this article, the authors present new detrital zircon Hf analyses from LHS and GHS samples spanning over 1000 km along the orogen that respectively show a striking similarity in age spectra and Hf isotope ratios.
Journal ArticleDOI
Using monazite and zircon petrochronology to constrain the P–T–t evolution of the middle crust in the Bhutan Himalaya
TL;DR: In this article, the ages of different growth zones in zircon and monazite in a garnet-bearing anatectic metapelite from the Greater Himalayan Sequence in NW Bhutan were investigated via a combination of thermodynamic modelling, microtextural data and interpretation of trace-element chemical ‘fingerprint’ indicators in order to link them to the metamorphic stage at which they crystallized.
