We report a new fluid inclusion dataset from Northeast Libyan speleothem SC-06-01, which is the largest speleothem fluid inclusion dataset for North Africa to date. The stalagmite was sampled in Susah cave, a low altitude coastal site, in Cyrenaica,... Read More about Enhanced Mediterranean water cycle explains increased humidity during MIS 3 in North Africa.

Mediterranean isolation preconditioning the Earth System for late Miocene climate cooling (2019)
Journal Article

© 2019, The Author(s). A global Neogene cooling trend culminated ~7 million years ago with the onset of Greenland glaciation. Increased ocean-atmosphere interaction and low- to high-latitude circulation are thought to be key factors in reorganizing...

A window into Africa’s past hydroclimates: The sisal_v1 database contribution (2019)
Journal Article
Braun, K., Nehme, C., Pickering, R., Rogerson, M., & Scroxton, N. (2019). A window into Africa’s past hydroclimates: The sisal_v1 database contribution. Quaternary, 2(1), Article 4. https://doi.org/10.3390/quat2010004

Africa spans the hemispheres from temperate region to temperate region and has a long history of hominin evolution. Although the number of Quaternary palaeoclimatic records from the continent is increasing, much of the history of spatial and temporal...

A depositional model for spherulitic carbonates associated with alkaline, volcanic lakes (2017)
Journal Article
Mercedes-Martín, R., Brasier, A. T., Rogerson, M., Reijmer, J. J., Vonhof, H., & Pedley, M. (2017). A depositional model for spherulitic carbonates associated with alkaline, volcanic lakes. Marine and Petroleum Geology, 86, 168-191. https://doi.org/10.1016/j.marpetgeo.2017.05.032

The South Atlantic Aptian ‘Pre-salt’ reservoirs are formed by a combination of spherulitic carbonates and Mg-rich clays accumulated in volcanic alkaline lake settings with exotic chemistries. So far, outcrop analogues characterised by metre-thick suc... Read More about A depositional model for spherulitic carbonates associated with alkaline, volcanic lakes.

Timing and causes of North African wet phases during the last glacial period and implications for modern human migration (2016)
Journal Article
Hoffmann, D. L., Rogerson, M., Spötl, C., Luetscher, M., Vance, D., Osborne, A. H., …Moseley, G. E. (2016). Timing and causes of North African wet phases during the last glacial period and implications for modern human migration. Scientific reports, 6(1), Article ARTN 36367. https://doi.org/10.1038/srep36367

We present the first speleothem-derived central North Africa rainfall record for the last glacial period. The record reveals three main wet periods at 65-61 ka, 52.5-50.5 ka and 37.5-33 ka that lead obliquity maxima and precession minima. We find add...

A test of the biogenicity criteria established for microfossils and stromatolites on quaternary tufa and speleothem materials formed in the “Twilight zone” at Caerwys, UK (2015)
Journal Article
Brasier, A. T., Rogerson, M. R., Mercedes-Martin, R., Vonhof, H. B., & Reijmer, J. J. G. (2015).

© 2015, Mary Ann Liebert, Inc. The ability to distinguish the features of a chemical sedimentary rock that can only be attributed to biology is a challenge relevant to both geobiology and astrobiology. This study aimed to test criteria for recognizin...

Qualitative and quantitative approaches in palaeohydrography: a case study from core-top parameters in the Gulf of Cadiz (2010)
Journal Article
Rogerson, M., Schönfeld, J., & Leng, M. J. (2011). Qualitative and quantitative approaches in palaeohydrography: a case study from core-top parameters in the Gulf of Cadiz. Marine Geology, 280(1-4), 150-167. https://doi.org/10.1016/j.margeo.2010.12.008

Palaeoceanography relies on the assumption that parameters measureable in sediment cores correlate reliably to hydrographic parameters. Areas of dynamic watermass mixing, which generally have steep hydrographic gradients, therefore provide both a tem...

It is widely accepted that modern humans originated in sub-Saharan Africa ≈150-200 thousand years ago (ka), but their route of dispersal across the currently hyperarid Sahara remains controversial. Given that the first modern humans north of the Saha... Read More about A humid corridor across the Sahara for the migration of early modern humans out of Africa 120,000 years ago.
