    Evaluability Assessment: A Systematic Approach to Deciding Whether and How to Evaluate Programmes and Policies

    Get PDF
    Evaluability assessment (EA) is a systematic approach to planning evaluation projects. It involves structured engagement by researchers with stakeholders to clarify intervention goals and how they are expected to be achieved, the development and evaluation of a logic model or theory of change, and provision of advice on whether or not an evaluation can be carried out at reasonable cost, and what methods should be used. To date, EA has been relatively little used in the UK, but it has begun to attract attention as a way of balancing the growing demand for evaluation with the limited resource available. As well as providing a sound basis for making decisions about whether and how to evaluate before resources are committed, EA can improve the translation of research into practice by ensuring that policy-makers and practitioners are involved from the beginning in developing and appraising evaluation options. Two EAs have recently been conducted in Scotland, which provide a model that can be applied to a wide range of interventions, programmes and policies at national, regional and local levels. What Works Scotland is keen to work with Community Planning Partnerships (CPPs) to identify opportunities for EA

    Field trip guide to the Onland Oligocene-Miocene Sedimentary Record, Eastern Taranaki Basin Margin

    Get PDF
    This field guide affords a north to south transect through examples of the Mesozoic to Quaternary sedimentary succession exposed in the Waikato, King Country and coastal strip of the eastern Taranaki basins, with particular focus on the Oligocene and Miocene deposits and how these link into the offshore parts of Taranaki Basin. The trip starts in Hamilton and ends at Tongaporutu on the north Taranaki coast, with overnight accommodation available at either Awakino or Mokau. Primarily under both local and more distant tectonic control, the stops provide examples of the various carbonate and terrigenous (locally volcaniclastic)-dominated facies associated with marginal marine, shoreline, shelf and slope-to-basin depositional settings, and their stratigraphic architecture and wider sequence stratigraphic context. Along the way, visits are recorded to basement greywacke, serpentinite and limestone quarries

    Note on paramoudra-like carbonate concretions in the Urenui Formation, North Taranaki: possible plumbing system for a Late Miocene methane seep field

    Get PDF
    A reconnaissance study of calcitic and dolomitic tubular concretions in upper slope mudstone of the Late Miocene Urenui Formation exposed along the north Taranaki coastline indicates that they have a complex diagenetic history involving different phases of carbonate cementation and likely hydrofracturing associated with build up of fluid/gas pressures. The concretions resemble classical paramoudra in the European chalk, but are not siliceous and do not have a trace fossil origin. Stable oxygen and carbon isotope data suggest that the micritic carbonate cements in the Urenui paramoudra were probably sourced primarily from ascending methane fluid/gases, and that they precipitated entirely within the host mudstone below the seafloor. We suggest the paramoudra may mark the subsurface plumbing networks of a Late Miocene cold seep system, in which case they have relevance to the evolution and migration of hydrocarbons in Taranaki Basin, at this site perhaps focussed along the Taranaki Fault. The presence of dislodged and mass-emplaced paramoudra in the axial conglomerate of channels within the Urenui mudstone suggests there could be a connection between the loci of seep field development and slope failure and canyon cutting on the Late Miocene Taranaki margin

    Contrasting carbonate depositional systems for Pliocene cool-water limestones cropping out in central Hawke's Bay, New Zealand

    Get PDF
    Pliocene limestone formations in central Hawke's Bay (eastern North Island, New Zealand) accumulated on and near the margins of a narrow forearc basin seaway within the convergent Australia/Pacific plate boundary zone. The active tectonic setting and varied paleogeographic features of the limestone units investigated, in association with probable glacioeustatic sea-level fluctuations, resulted in complex stratigraphic architectures and contrasting types of carbonate accumulation on either side of the seaway. Here, we recognise recurring patterns of sedimentary facies, and sequences and systems tracts bounded by key physical surfaces within the limestone sheets. The facies types range from Bioclastic (B) to Siliciclastic (S) end-members via Mixed (M) carbonate-siliciclastic deposits. Skeletal components are typical cool-water associations dominated by epifaunal calcitic bivalves, bryozoans, and especially barnacles. Siliciclastic contents vary from one formation to another, and highlight siliciclastic-rich limestone units in the western ranges versus siliciclastic-poor limestone units in the eastern coastal hills. Heterogeneities in facies types, stratal patterns, and also in diagenetic pathways between eastern and western limestone units are considered to originate in the coeval occurrence in different parts of the forearc basin of two main morphodynamic carbonate systems over time
