The strategic and the stratigraphic: a working paper on the dynamics of organisational evolution. [PDF]

open access: yes, 2012
Despite large debates over fundamental issues a broadly evolutionary paradigm of organisations is growing in legitimacy. It may though be preferable to replace the metaphor of the organisation as an organism with the literal assertion that both social ...

Stratigraphy and geomorphology of Des‐Cubierta Cave (Pinilla del Valle, Madrid, Spain): Geological insights into a Neanderthal symbolic accumulation of large crania

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Des‐Cubierta Cave, part of the Calvero de la Higuera complex, is situated in the intramountainous upper valley of the Lozoya River within the Guadarrama Range. The cave's geological, palaeontological, and archaeological record reveals a complex history of sedimentary and anthropogenic processes spanning hundreds of thousands of years ...

Timing of initiation of reverse displacement on the Taranaki Fault, northern Taranaki Basin: Constraints from the on land record (Oligocene Te Kuiti Group) [PDF]

open access: yes, 2008
Structures associated with the wedge of basement overthrust into Taranaki Basin along the Taranaki Fault, are regarded as hydrocarbon plays and have been tested by drilling through the tip of the overthrust.

Challenges in dating blanket peat and implications for understanding its initiation in Ireland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Blanket peat is widespread in maritime extra‐tropical environments. Prehistoric land‐use activity was traditionally invoked as the stimulus of blanket peat initiation in the British Isles, but recently, climate has been viewed as the driver of peat formation.

Growth and form of the mound in Gale Crater, Mars: Slope-wind enhanced erosion and transport [PDF]

open access: yesarXiv, 2012
Ancient sediments provide archives of climate and habitability on Mars. Gale Crater, the landing site for the Mars Science Laboratory (MSL), hosts a 5 km high sedimentary mound. Hypotheses for mound formation include evaporitic, lacustrine, fluviodeltaic, and aeolian processes, but the origin and original extent of Gale's mound is unknown. Here we show

Cryptotephra from a ~120 ka Tondano eruption in a sediment core from Lake Towuti (Indonesia)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Southeast Asia is one of the most volcanically active regions in the world, yet their long‐term eruptive history has been comparatively little studied. In particular, little work has explored the potential of sedimentary archives to record distal cryptotephra, which may help in identifying some of the region's larger Quaternary eruptions. Here,

Thermally Optimised Raman Spectroscopy for Safe Analysis of Wall Paintings and Application to Lorenzetti's Masterpiece

open access: yesJournal of Raman Spectroscopy, EarlyView.
A portable dual‐wavelength Raman system (exc. 785 and 1064 nm) based on a four‐channel innovative probe for safe characterisation of artworks is presented. This instrument enables non‐contact real‐time monitoring of the temperature rise and laser power modulation to prevent overheating during Raman spectroscopy, through direct emissivity and ...
