Far-field deformation resulting from rheologic differences interacting with tectonic stresses: an example from the Pacific/Australian plate boundary in Southern New Zealand
The Miocene in Southern New Zealand was dominated by strike-slip tectonics. Stratigraphic evidence from this time attests to two zones of subsidence in the south: (a) a middle Cenozoic pull-apart basin and (b) a regionally extensive subsiding lake complex, which developed east and distal to the developing plate boundary structure....Upton, Phaedra ; Craw, Dave ; Walcott, Rachel

Determination of zeolite-group mineral compositions by electron probe microanalysis (EPMA)
A new protocol for the quantitative determination of zeolite group mineral compositions by electron probe microanalysis (EPMA, wavelength dispersive spectrometry) under ambient conditions, is presented. The method overcomes the most serious challenges for this mineral group, including new confidence in the fundamentally important Si-Al ratio. Development tests were undertaken on...Campbell, L S ; Charnock, J ; Dyer, S ; Hillier, S ; Chenery, Simon …

Squeezing river catchments through tectonics: shortening and erosion across the Indus Valley, NW Himalaya
Tectonic displacement of drainage divides and the consequent deformation of river networks during crustal shortening have been proposed for a number of mountain ranges, but never tested. In order to preserve crustal strain in surface topography, surface displacements across thrust faults must be retained without being recovered by consequent erosion....Sinclair, H D ; Mudd, S M ; Dingle, E ; Hobley, D E J ; Robinson, R …

Museum during a crisis
These are strange times. As I write this (16th March 2020), the number of coronavirus or rather Covid-19 infections is rapidly increasing and I am uncertain whether our Museum, the National Museum of Scotland (NMoS), will even be open to the public this time next week. This 160 year old...Walcott, Rachel

Stress fields of ancient seismicity recorded in the dynamic geometry of pseudotachylyte in the Outer Hebrides Fault Zone, UK
Heterogeneous sequences of exhumed fault rocks preserve a record of the long-term evolution of fault strength and deformation behaviour during prolonged tectonic activity. Along the Outer Hebrides Fault Zone (OHFZ) in NW Scotland, numerous pseudotachylytes record palaeoseismic slip events within sequences of mylonites, cataclasites and phyllonites. To date, the kinematics...Campbell, L R ; Lloyd, G E ; Phillips, R J ; Walcott, Rachel ; Holdsworth, R E

GeoCASe 2.0 and the evolution of data from physical specimen to the digital
As Principal Curator of the National Museums Scotland’s (NMS) 200 year old ‘Earth System collection, a collection of 70000 minerals, rocks and meteorites, one of my responsibilities is to ensure the collection puts its best foot forward into the Digital Era. So for the past few years, I have lead...Walcott, Rachel

Reaching Further with Earth Science Data
Earth Sciences cover a broad spectrum of research fields such as petrology, sedimentology, structural geology, seismology, and geomorphology, to name a few, which aim to understand interrelated processes on the surface and in the interior of our planet. Many of the research questions studied in the Earth sciences, such as,...Walcott, Rachel ; Lehnert, Kerstin
