Gold enrichment characteristics and exploration prospects in Zambia: Based on 1 ∶ 1000000 geochemical mapping

China Geology, 2022
The 1∶1000000 geochemical mapping of Zambia provides catchment sediment geochemical data for 58 elements including Au from 746 sediment samples at 736 sampling sites, corresponding to a sampling density of about one site per 1000 km2.

Spatio‐Temporal Variations in Sediment Delivery as a Response to Rapid Quaternary Climate Change in the Lake Malawi Rift, East Africa

Journal of Geophysical Research: Earth Surface, Volume 128, Issue 10, October 2023., 2023
Abstract The interplay of rapid climate change and tectonics drives landscape development, sediment routing, and deposition in early‐stage continental rift systems. The Lake Malawi Rift, in the Western Branch of the East African Rift, is an archetype of a juvenile rift and an ideal natural laboratory for evaluating lacustrine source‐to‐sink systems on ...

Heterogeneous Strain Distribution in the Malawi (Nyasa) Rift, East Africa: Implications for Rifting in Magma‐Poor, Multi‐Segment Rift Systems

Tectonics, Volume 42, Issue 9, September 2023., 2023
Abstract Half‐graben basins bounded by border faults typify early‐stage continental rifts. Deciphering the role that intra‐rift faults play in rift basin development is challenging as patterns of early‐stage faulting are commonly overprinted by subsequent deformation; yet the characterization of these faults is crucial to understand the fundamental ...

Atmospheric Methane: Comparison Between Methane's Record in 2006–2022 and During Glacial Terminations

Global Biogeochemical Cycles, Volume 37, Issue 8, August 2023., 2023
Abstract Atmospheric methane's rapid growth from late 2006 is unprecedented in the observational record. Assessment of atmospheric methane data attributes a large fraction of this atmospheric growth to increased natural emissions over the tropics, which appear to be responding to changes in anthropogenic climate forcing.

Two New Shellear Species (Gonorhynchiformes: Kneriidae), from the Luansa River (Upper Congo Basin): Hidden Diversity Revealed by Integrative Taxonomy

Diversity, 2023
Two new Kneria species, K. luansaensis sp. nov. and K. maxi sp. nov., are described from the Luansa River, a left bank tributary of the lower Luapula in the Bangweulu–Mweru ecoregion, based on an integrative approach using morphological and COI barcoding

The Deep Basin and Underlying Basement Structure of the Tanganyika Rift

Tectonics, Volume 42, Issue 7, July 2023., 2023
Abstract The oldest structures in a rift basin define incipient rift architecture, and commonly modulate the patterns of landscape evolution, sedimentation, and associated hazards in subsequent phases of rift development. However, due to deep burial beneath younger, thick syn‐rift sequences, and limited resolution of seismic imaging, critical early ...

Genetic patterns in three South African specialist antelope species: Threats, conservation management and their implications

Conservation Science and Practice, Volume 4, Issue 12, December 2022., 2022
In South Africa, there has been great interest to translocate animals, sometimes with little consideration for the genetic integrity of the species. Thus, in this review, we collate scientific information to better inform decision‐making and review these management practices and their effects on species integrity.

Wild foods from forests: Quantities collected across Zambia

People and Nature, Volume 4, Issue 5, Page 1159-1175, October 2022., 2022
Abstract Forests provide an immense range of benefits to people, many of which are not prioritized by forest policy because they are difficult to quantify. Wild foods from forests enhance the quality of diets for those who consume them and provide income for those who sell or trade them.

Development of the Nyika Plateau, Malawi: A Long Lived Paleo‐Surface or a Contemporary Feature of the East African Rift?

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 8, August 2022., 2022
Abstract Northern Malawi's Nyika Plateau is a 3,700 km2 large, highly elevated (∼2,500 m) plateau located at the western margin of the Miocene‐Recent Malawi rift and the confluence of multiple Proterozoic orogenic belts. Neighboring asthenospheric upwelling in the Rungwe Volcanic Province, associated with the active East African Rift, has created ...
