The continental mass of Australia (Fig. 8.1) is made up of four great structural units, to which we may add a fifth represented in the fringing island arcs to the north and east. The oldest and most extensive unit is the Precambrian craton which comprises most of the central and western parts of the continent where Precambrian rocks are exposed beneath

Density heterogeneity of the cratonic lithosphere: A case study of the Siberian Craton
Gondwana Research, 2015Using free-board modeling, we examine a vertically-averaged mantle density beneath the Archean–Proterozoic Siberian Craton in the layer from the Moho down to base of the chemical boundary layer (CBL). Two models are tested: in Model 1 the base of the CBL coincides with the LAB, whereas in Model 2 the base of the CBL is at a 180 km depth.

“Lower-crustal suite” xenoliths occur in “on-craton” and “off-craton” kimberlites located across the south-western margin of the Kaapvaal craton, southern Africa. Rock types include mafic granulite (plagioclase-bearing assemblages), eclogite (plagioclase-absent assemblages with omphacitic clinopyroxene) and garnet pyroxenite (“orthopyroxene-bearing ...

Granite Landforms of the Indian Cratons
2014The granite landforms of peninsular India, particularly in the semi-arid continental interior, form rugged clusters of oddly shaped bedrock monoliths and boulders corresponding to stripped weathering fronts. By no means unique to India, the array of landforms typical of most tropical landscapes and commonly described in geomorphology textbooks is ...
