KIMBA - Seismic deployments in the Kimberley Region 1997, 1998

Stage one - KIMBA97
From July to October 1997 a set of broad-band instruments were deployed in the Kimberley region, both on the King Leopold and Halls creek fold belt and the interior of the block (Figure 1). This region of northern Australia has been the subject of very little geophysical investigation on crustal and larger scales, and this year's station placements were designed to build on the information obtained from the stations in the SK3 and SK6 legs of the SKIPPY experiment to improve knowledge of the region.

Stage two - KIMBA98
From May to October 1998 a set of 14 broad-band instruments were deployed through the Kimberley region, crossing both the King Leopold and Halls Creek fold belts and the interior of the block including the remote northern region (fig 1). The instruments deployed in 1998 (KB) indicated by filled symbols were placed to improve the coverage from the 1997 deployment (KA) shown as open symbols and the stations in the SK3 and SK6 legs of the SKIPPY experiment indicated in grey. The object of this study is to try to characterise this complex region, where very little geophysical investigation has been carried out on crustal and larger scales.
