Lenhardt, Nils; Hornung, Jens; Hinderer, Matthias; Böhnel, Harald; Torres-Alvarado, Ignacis S.; Trauth, Nico (Wiley-Blackwell, 2011-04)Volcanic terrains such as magmatic arcs are thought to display the most complex surface environments on Earth. Ancient volcaniclastics are notoriously difficult to interpret as they describe the interplay between a single ...

Eriksson, Patrick George; Bartman, R.D. (Reynard Dirk); Catuneanu, Octavian; Mazumder, Rajat; Lenhardt, Nils (Elsevier, 2012-07)The Magaliesberg Formation sandstones within the upper part of the Pretoria Group are interpreted as a second-order highstand systems tract within an overall clastic epeiric marine setting, where episodic braided fluvial ...

Fan, Aiping; Yang, Renchao; Lenhardt, Nils; Wang, Meng; Han, Zuozhen; Li, Jinbu; Zhao, Zhongjun (Elsevier, 2019-05)Tight sandstone gas reservoirs constitute an important type of unconventional gas resources and may be of crucial significance as environment-friendly source of energy in the world. However, the dynamics of densification ...

Eriksson, Patrick George; Lenhardt, Nils; Wright, D.T.; Mazumder, Rajat; Bumby, Adam John (Elsevier, 2011)The application of the onset of supercontinentality, the “Great Oxidation Event” (GOE) and the first global scale glaciation in the Neoarchaean-Palaeoproterozoic as panacea-like events providing a framework or even ...

Lenhardt, Nils; Altermann, W.; Humbert, F.; De Kock, M. (Geological Society of South Africa, 2020-12)The Palaeoproterozoic Hekpoort Formation of the Pretoria Group is a lava-dominated unit that has a basin-wide extent throughout the Transvaal sub-basin of South Africa. Additional correlative units may be present in the ...

Ngwa, Caroline Neh; Lenhardt, Nils; Le Roux, Petrus; Mbassa, Benoit Joseph (Elsevier, 2019-10)With seven major eruptions in the 20th century, Mount Cameroon is one of the most active volcanoes in Africa. However, information on the volcano's plumbing system is still relatively scarce. In order to contribute to ...

Lenhardt, Nils; Eriksson, Patrick George; Catuneanu, Octavian; Bumby, Adam John (Elsevier, 2012-09)The time of deposition of the Pretoria Group between 2.32 and 2.06 Ga on South Africa’s Kaapvaal Craton was characterized by the first major increase in atmospheric oxygen. It was accompanied by the extrusion of significant ...

Bilal, Ahmer; Yang, Renchao; Lenhardt, Nils; Han, Zuozhen; Luan, Xiwu (Elsevier, 2023-11)The sedimentary rocks of the Paleocene Hangu Formation in the Yadgaar Section of the Upper Indus Basin in northern Pakistan, have been the subject of an integrated field, petrographical, and sedimentological investigation. ...

Lenhardt, Nils; Böhnel, Harald; Hinderer, Matthias; Hornung, Jens (Elsevier, 2013-05)Sources of ancient volcanic rocks are often unknown if they are either eroded and/or covered by younger deposits. This problem, as well as the provenance of reworked volcaniclastic, fluvial and mass-flow deposits, can ...
-
Lenhardt, Nils; Herrmann, Mark; Goetz, A.E. (Annette) (SEPM Society for Sedimentary Geology, 2013-10)Palynomorph preservation in sedimentary rocks is strongly affected by various taphonomic factors related to transport, deposition, diagenesis and preservation potential. The palynological record may contribute to distinguish ...
