Inclusion-localised crystal-plasticity, dynamic porosity, and fast-diffusion pathway generation in zircon
No full textA population of oscillatory zoned, igneous zircon grains in a Javanese andesite contains fluid and mineral inclusions (up to 10μm across) trapped during zircon growth. Orientation contrast imaging and orientation mapping by electron backscatter diffraction reveal that crystal-plastic deformation overprints growth zoning and has localized around 1-10μm pores and inclusions. Cumulative crystallographic misorientation of up to 25° around pores and inclusions in zircon is predominantly accommodated by low-angle ((010) slip. A distinctly different population of sub-micron pores is present along subgrain boundaries and their triple junctions. These are interpreted to have formed as a geometric consequence of dislocation interaction during crystal-plasticity. Dislocation creep microstructures are spatially related to differences in cathodoluminescence spectra that indicate variations in the abundance of CL-active rare earth elements. The extent of the modification suggests deformation-related fast-pathway diffusion distances that are over five orders of magnitude greater than expected for volume diffusion. This enhanced diffusion is interpreted to represent a combination of fast-diffusion pathways associated with creep cavitation, dislocations and along low-angle boundaries. These new data indicate that ductile deformation localised around inclusions can provide fast pathways for geochemical exchange. These pathways may provide links to the zircon grain boundary, thus negating the widely held assumption that inclusions in fracture-free zircon are geochemically armoured once they are physically enclosed. © 2011.Nicholas E.

Eric Voegelin's thought and its significance for political theology
No full textThe philosopher Eric Voegelin (1901-85) held that at the
heart of an adequate political philosophy must be a
philosophy of consciousness. This study discusses
Voegelin's thought in its significance for "political
theology", by which is understood that mode of theological
thinking which focuses on the relationship of
Christian faith to the pursuit of social justice.
The study falls into two parts. Part One is an exposition
of Voegelin's thought with the perspective of political theology continuously in mind. Chapter One justifies the choice of this perspective. There follow chapters an the symbol of the metaxy, which Voegelin takes from Plato and which is fundamental to his thought, and on the rational structure of symbols and their articulation. Then the modes of symbolic discourse most important for Voegelin are considered in turn: myth, classical philosophy, Christian theology, history, and politics. Part One finishes with a discussion of Voegelin's work on the Hebrew and Christian Scriptures.
Part Two concentrates on three topics central to the
concerns of Voegelin and political theologians alike.
Besides being intrinsically important, these topics
permit one to estimate how valuable is Voegelin's work as
a resource for political theology. The topics are the
relationship between individual and societal transformation;
the scope and limits of Christian hope for the attainment of a just social order within history; and the nature of political responsibility and irresponsibility in the light of faith. The thesis ends with a summary of its conclusions.
It is argued that Voegelin's thought offers a powerful
and constructive challenge to political theologians, but
that political theology in turn provides a vantage point
which reveals certain serious shortcomings in Voegelin's
powerful thought. In particular, it is argued that
Voegelin fails to articulate adequately the social
implications of his own philosophical principles
The artistic self: identity and self-representation in Nicholas Maw’s life studies: Portfolio of compositions and critical writing
No full textIn his article 'The Death of the Author', Roland Barthes posits that the intentions and identity of an author are irrelevant to the understanding of an artwork. Yet in his analysis of a text by Balzac, Barthes inadvertently demonstrates that there are basic thematic categories associated with an artist's identity, which are intrinsic to a work's interpretation. This thesis proposes that the author of an artwork functions as a semiotic curator, collating signifiers from within these external categories in order to reflect their understanding of the world. Taking as a case study Nicholas Maw's 1976 score Life Studies – a piece described by the composer as being based on his own life – this experiential understanding of identity and self is explored through the lens of David Hume's bundle theory, where the unified experience of self is created through the collection of a series of perceptions. This thesis hypothesises that there are five key categories of perception that constitute Maw's artistic self in Life Studies: simulacra, narrative, design, agency, and nostalgia. Methodologically, these five areas – or rhizomes – are presented through a tripartite study, in an attempt to combine the three distinct disciplines which the philosopher Gilles Deleuze believed approached a holistic understanding of reality: philosophy, analysis, and – in the accompanying portfolio – composition (creativity)
The Piermont allochthon revisited and redefined at its type locality
No full textRegional lithostratigraphic and structural mapping of the Piermont allochthon of northwestern New England at its type locality indicates that the Foster Hill fault, the supposed sole thrust, is a stratigraphic boundary. Rather, the allochthon lies above the Bean Brook fault, covers a much smaller area than suggested previously, and is limited to the vicinity of Piermont, western New Hampshire. The allochthon, which primarily consists of rocks correlated with the Silurian age Rangeley Formation of Maine, has horizons of metamorphosed polymictic conglomerate at its base. Rocks directly below theallochthon are correlated with the metasedimentary, Ordovician-aged Albee Formationand contain abundant metamorphosed dykes and sills that do not cross the sole detachmentof the allochthon. Analysis of macro- and mesoscale structures indicates local reservation of fold hinges and overprinting foliations oblique to and later than those previously described and has allowed the deformation history to be signifi cantly extended by several events. Emplacement of the allochthon early in the deformation history at metamorphic conditions caused NW-SE elongation lineations of clasts in conglomerate at the base of the allochthon. The relict foliations and fold hinges are commonly preserved below the allochthon, suggesting that these rocks have had a more protracted deformation history relative to rocks in the allochthon. The new interpretation of the Piermont area provides a framework to build a more thorough tectonic history for this part of the New England Appalachians

Trench-parallel fast axes of seismic anisotropy due to fluid-filled cracks insubducting slabs
No full textSubducting slabs experience deformation and metamorphism as they descend into the upper mantle. Thepresence of hydrous minerals gained through the interaction with sea water at mid-ocean ridges, transformfaults or the outer rise ensures that dehydration reactions will be important at deeper levels. We describefield evidence for brittle hydrofracture in previously subducted rocks from the Western Alps, with a freeaqueous fluid phase produced by dehydration reactions in the host blueschists and serpentinites. Theprotracted history of dehydration reactions, ductile deformation, fluid flow and brittle vein formation inthese rocks implies that fluid-filled cracks are continuously produced within the dehydration window. Thepresence of abundant fluid-filled cracks at these depths has important implications for the seismic anisotropygenerated within slabs, which has largely been overlooked. The effects of fluid-filled crack damage on theelastic properties of a blueschist and serpentinite within the slab at depth have been modelled, and show asignificant rotation of the fast axes of P and S1 waves to be trench-parallel for receiving stations in the forearc,above the dehydrating portion of the slab. This model provides an alternative explanation for suprasubductionzone seismic anisotropy that does not require high-stress, high-water conditions, or trenchparallelflow in the supra-subduction zone mantle wedge
