Abstract
The Hart Dolerite is the intrusive portion of the Carson-Hart
Large Igneous Province (LIP; Hoatson et al., 2006;
Tyler et al., 2006) in the Kimberley region of northern
Western Australia. It forms a series of sills and some dykes
that intrude the lower Kimberley Basin (King Leopold
Sandstone and Carson Volcanics of the Kimberley Group)
and the underlying Speewah Basin at a depth of 2-3 km
beneath the eruptive surface. Although large areas of the
Kimberley and Speewah Basins are underlain by the sills,
they are particularly well exposed around the upturned
and folded margins of the basins (Fig. 1). The mean U-Pb
crystallization ages of zircon and baddeleyite obtained
from the granophyre and upper mafic sills in the Hart
Dolerite is 1797 ± 11 Ma (Sheppard et al. 2012).
