Abstract Magnetotelluric (MT) survey results from the Late Archean Manica greenstone belt, an extension of the Odzi‐Mutare greenstone belt of the Zimbabwe Craton, are presented. A total of 33 MT stations were acquired on an irregular grid with an average station spacing of approximately 5 km.

Crustal Structure Across the Okavango Rift, Botswana: The SEISORZ Wide‐Angle Seismic Experiment
Abstract The Okavango Rift Zone (ORZ) is an incipient continental rift in Botswana at the terminus of the Southwestern Branch of the East African Rift System. The lack of syn‐rift magmatism and tectonic processes overprinting pre‐rift structures provide an opportunity to investigate incipient‐stage rift processes and the role of pre‐existing structures

Abstract We present elemental geochemistry and multiple isotopic systematics (Re‐Os, Lu‐Hf, Sm‐Nd and Sr) for mantle peridotite xenoliths from Lashaine in northern Tanzania. We use the data to examine how the major Proterozoic tectono‐thermal events that affected the crust of the western Tanzanian craton are imprinted on the lithospheric mantle in the ...

Abstract Martian carbonate‐bearing rocks are compelling targets for exploration because they preserve detailed records of past aqueous processes, climate, and habitability. The Margin unit in Jezero crater is a distinct olivine‐ and carbonate‐bearing unit stratigraphically underlying the western fan, lining the inner margin of the western crater rim ...

This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.

The karst geothermal reservoir in Xiong'an New Area is a representative example of an ancient buried hill geothermal system. However, published heat flow data are predominantly derived from the Cenozoic sedimentary cap.
