title: Early Jurassic palaeoenvironments in the Surat Basin, Australia - marine incursion into eastern Gondwana

authors: La Croix, Andrew D.

subjects: Science & Technology

abstract: Interpretations of palaeodepositional environments are important for reconstructing Earth history. Only a few maps showing the Jurassic depositional environments in eastern Australia currently exist. Consequently, a detailed understanding of the setting of Australia in Gondwana is lacking. Core, wireline logs, two‐dimensional and three‐dimensional seismic from the Precipice Sandstone and Evergreen Formation in the Surat Basin have been used to construct maps showing the evolution of depositional environments through the Early Jurassic. The results indicate the succession consists of three third‐order sequences (Sequence 1 to Sequence 3) that were controlled by eustatic sea level. The lowstand systems tract in Sequence 1 comprises braidplain deposits, confined to a fairway that parallels the basin centre. The strata were initially deposited in two sub‐basins, with rivers flowing in different orientations in each sub‐basin. The transgressive systems tract of Sequence 1 to lowstand systems tract of Sequence 3 is dominated by fluvio–deltaic systems infilling a single merged basin centre. Finally, the transgressive and highstand systems tracts of Sequence 3 show nearshore environments depositing sediment into a shallow marine basin. In the youngest part of this interval, ironstone shoals are the most conspicuous facies, the thickness and number of which increase towards the north and east. This study interprets a corridor to the open ocean through the Clarence–Moreton Basin, or the Carpentaria and Papuan basins, evidence of which has been eroded. These results challenge a commonly held view that eastern Australia was not influenced by eustasy, and propose a more dynamic palaeogeographic setting comprising a mixture of fluvial, deltaic and shallow marine sedimentary environments. This work can be used to unravel the stratigraphic relationships between Mesozoic eastern Australian basins, or in other basins globally as an analogue for understanding the complex interplay of paralic depositional systems in data poor areas.

title: Women, sport and the media: A complex terrain

authors: Bruce, Toni

subjects: women

abstract: In this chapter I examine coverage of women’s sport, exposing the ways in which the sports media can simultaneously challenge and reinforce dominant assumptions that sport is primarily a male domain. I first summarize the extensive research that shows how the ‘everyday’ sporting activities of female athletes are trivialised and ignored by mediasport, before turning to a discussion of the times and places when female athletes visibly enter into public consciousness. Finally, I present examples from two case studies; one which disrupts and one which supports traditional ways of understanding gender.

title: The processes involved in formulating a marae-based Māori language regeneration plan for Whakamārama marae: Outline, analysis and evaluation

authors: Lewis, Roger

subjects: New Zealand

abstract: We provide here a criterion referenced evaluation of the processes involved in the creation of a Māori language regeneration strategy for Whakamārama marae. Working voluntarily and often under difficult circumstances, core group members demonstrated that they possessed the essential characteristics of commitment, motivation and determination. In addition, they demonstrated the willingness and ability to use existing skills and knowledge effectively and to develop further skills and knowledge as the project proceeded. Perhaps most important, they developed a caring and effective working culture. However, the weaknesses of the project included a lack of preparation and planning prior to the commencement of the project which led to delays in producing outcomes and some loss of momentum. This also led, indirectly, to the views of two or three members of the core group being overrepresented in the language planning goals. We believe that the information and analysis provided here are likely to be of interest to any language community involved in micro-level language regeneration activities of a similar type.
