The Neuquen Basin, Argentina: A Case Study in Sequence Stratigraphy and Basin Dynamics (Geological Society Special Publication)

The Neuqu? ©n Basin of northern Patagonia offers a very good case research in basin research and series stratigraphy. The basin is likely one of the biggest petroleum provinces in South the United States and encompasses a dramatic list of relative sea point alterations in addition to a different and globally very important palaeontological checklist.

24 Oviform Areography deformation By means of the same "ruler and compass" procedure, and under the same ideal conditions stated before, it is easy to see that if we have two centres of dispersal having the same growth rate, the universe (continent or island) will be divided in two by a straight frontier. If the centres have different growth rates, the faster growing species will completely surround the slower one, provided there is enough land for it. Otherwise, their limits will tend to have a parabolic form, from coast to coast, concave for the fast-growing taxon and convex for the slow-growing one.

Areography Relation between, the total number of subspecies, and the number of internal (Mediterranean) sub­ species. Data correspond to sixty-three species of North American mammals. The partitioning model B is based on Fig.

These simple models are easily simulated by drawing concentric circles starting from the centres or "propagules". The radius increase will vary according to the growth rate assigned to each point, and each species will grow until it collides with its neighbours. The final shape of the area of a given "species" will depend on the opportunities given by the surrounding species and on the distances between the different centres of dispersal. If we take three centres of dispersal (A, B, C , Fig. 4) with different growth rates, C being the fast-growing species, it will depend on A and B's growth rates whether a closed or open passage or route to overflow beyond AB is found.
