A study reveals that the oldest continental crust on Earth is slowly being broken up by shifting tectonic forces.

Sulfide inclusions in diamonds from the 90-Ma Jagersfontein kimberlite, intruded into the southern margin of the Kaapvaal Craton, were analyzed for their Re-Os isotope systematics to constrain the ...

In the Kaapvaal Craton, majorite inclusions follow different trends. Here, compositions indicate strong interaction between oxidized melts and the mantle, consistent with the presence of mantle plumes ...

Bruce Kjarsgaard (Geological Survey of Canada, Ottawa) reviewed kimberlite eruptive models based on 1970s and 1980s research in South Africa. He explained the revision of these models after new ...

Western Australia’s Pilbara region is known to host orogenic gold deposits, and the area became a growing hotspot for high-grade conglomerate gold exploration, with some geologists comparing the ...

It's located on the eastern edge of the Kaapvaal Craton which was once part of a supercontinent called Vaalbara that existed from 3.6 to 2.2 billion years ago before splitting into two separate ...

But something about the cratons had long puzzled geologists. Some, such as the Kaapvaal craton in southern Africa, are topped by vast plateaus that are rimmed by dramatic escarpments.

I started my PhD at TCD in July 2023, working with Dr Emma Tomlinson. My PhD project focuses mainly on quantifying the thickness of the lithospheric mantle beneath the Kaapvaal craton, and this ...

The Pilbara Craton is one of only two crust pieces that date back to the Archaean Eon, which lasted from 3.8 billion to 2.5 billion years ago. Moreover, this area contains some of the oldest rocks on ...

The Pilbara Craton is one of only two pieces of crust known to date back to the Archaean Eon (3.8 billion to 2.5 billion years ago) and hosts some of the oldest rocks on our planet.

The Hamersley Range in Western Australia stands as the second oldest mountain range globally, with an age of approximately 3.4 billion years. Forming part of the Pilbara Craton, this ancient ...
