Recent Refinement

Understanding the genesis and habitat of hydrocarbons in a sedimentary basin takes knowledge of that basin at many levels, from basic infill geology to petroleum systems, plays, prospects and detailed sequence stratigraphy. While geophysics can define the basins and their internal structures, biostratigraphy and paleogeography provide greater understanding of basin geology. Micropaleontology and palynology are the chief tools that we need to define both the environment and dimension of time.As an example, the reconstruction of the Tasman Sea region to the mid-Cretaceous (ca 120 Ma) shows that the hydrocarbon-producing Gippsland and Taranaki petroleum basins developed at similar latitudes and in similar geological contexts. Other basins within the region have been lightly explored and need evaluation as to the value of further exploration.As paleontology has developed separately in Australia and New Zealand, comparison of biostratigraphic zones and their chronostratigraphy is critical to understand the similarity or otherwise of the sedimentary record of the two regions. Recent refinement of the NZ timescale and comparative studies on Gippsland Basin wells by NZ paleontologists have provided some key insights that enable us to compare the geological history of both regions more closely, and to recognise similarities in petroleum systems that may enhance petroleum prospects on both sides of the Tasman Sea.

The Masses

Supported by the great weight of Hutton's authority, his views, with which those of Haast and the early views of Hector were in general agreement, have gained wide acceptance, notwithstanding the opposition of McKay. Marshall, for example, as late as 1911 wrote as follows: “The great elevation [Mesozoic orogenic movement] was succeeded by nearly as great a depression. The majestic mountain ranges were gradually lowered until nothing but a chain of islands showed above sea level. To what a great extent this movement prevailed is seen at Lake Te Anau, where the Oamaru formation, some 3,000 feet thick, rises to the tops of the mountains. At Wakatipu and in the Rangitata valley the Oamaru rocks are found in the recesses of the mountains. In the Trelissick basin and between the masses of the Kaikoura ranges there was deep water. The valleys of the tributaries of the Buller are filled with Oamaru sediments.”

As is well known, the skeleton or oldermass of New Zealand is largely composed of a mass of deformed sedimentary rocks, the precise ages of the members of which are in doubt but do not affect the problem under consideration. The most profound deformation of this vast sedimentary group took place in late Jurassic or early Cretaceous times during what may be termed the “Mesozoic orogenic period”, when probably a great mountain range came into existence.

Iconic Status

The Central Otago region, with its cold winters and hot summers, and valley floors with uplift mountains is definitely "a world of difference". At the NZGA conference in Alexandra in 1966 John Hercus stated "Central Otago has a lure which sets it apart from the rest of New Zealand. Its characteristics of geology, topography and climate, its history of occupation and exploitation, its scenery at once forbidding and yet strangely fascinating - these features combine to cast a spell which few who have been exposed, can ever fully escape" (Hercus 1966). The region and its high country have an iconic status epitomised by the "Southern Man" stereotype. This places Central Otago deep in the psyche of the nation. With this goes a unique and significant set of conditions under which farming must take place. Not only does the region have the biophysical challenges of soils, water and climate to contend with, but a wider set of values, often imposed from elsewhere. Fifty years after that first conference we remain challenged. What are the opportunities in front of us and how should we best accommodate the challenge of maintaining a viable enterprise and at the same time, respecting the intense public and customer interest in our use of land and livestock? Central Otago and the associated high country of the Lakes district and McKenzie basin can be divided into three farming types. These are the valley floor irrigable type, the flat and downland dryland regions, and the high country. Each of these has challenges that are at times unique, but often overlap with problems faced in other regions.
