The African continent (Fig. 6.1) has as its basement a huge platform of crystalline rocks partially masked by flat lying cover-successions of many ages. Towards the eastern, northern and western coasts, the crystalline complexes descend in many places beneath successions of Mesozoic and Tertiary sediments deposited in marginal marine basins.

Cratonic Lithosphere Delamination and Relamination Explain the Temporal Variation of Cratons
2023Cratonic lithosphere delamination has been frequently suggested in recent studies. However, the fate of the delaminated Sub-Cratonic Lithospheric Mantle (SCLM) has not been thoroughly investigated. Here, we use 2D numerical models to study the evolution of initially delaminated SCLM whose density is initially larger than that of the ambient mantle. Our

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

From a geological standpoint, the Indian subcontinent can be separated into two contrasting regions. To the south, bounded by fracture-coastlines, lies the triangular cratonic region of Peninsular India and Ceylon which has remained stable since early Palaeozoic times.

Thermal regime of the North China Craton: Implications for craton destruction
Earth-Science Reviews, 2015Abstract This paper presents an overview of the thermal studies dealing with heat flow data, lithospheric thermal thickness, basin thermal history, and thermal modeling in the North China Craton (NCC), with aim to provide ideas for geodynamical mechanism on the NCC destruction.
