Bordy, Emese M.; Bumby, Adam John; Catuneanu, Octavian; Eriksson, Patrick George (Society for Sedimentary Geology, 2004)Sandstone pillars in the Lower Jurassic eolian strata of the Clarens Formation are concentrated in clusters, with up to four pillars within 25 m2 in two localities in the Tuli Basin of northern South Africa and southern ...

Assessment of chemical and mineralogical characteristics of airborne dust in the Sistan region, Iran Rashki, Alireza; Eriksson, Patrick George; Rautenbach, Cornelis Johannes de Wet; Kaskaoutis, Dimitris G.; Grote, Wiebke; Dykstra, J. (Elsevier, 2013-01)Windblown transport and deposition of dust is widely recognized as an important physical and chemical concern to climate, human health and ecosystems. Sistan is a region located in southeast Iran with extensive wind ...

Van Dijk, D. Eduard; Eriksson, Patrick George (Taylor and Francis, 2021)The Lower Jurassic Clarens Formation (Stormberg Group, Karoo Supergroup, Main Karoo basin) contains relatively common vertebrate trackways impressed into apparently soft to firm, fine sediment beds preserved within the ...

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 ...

Allen, P.A.; Eriksson, Patrick George; Alkmim, F.F.; Betts, P.G.; Catuneanu, Octavian; Mazumder, Rajat; Meng, Q; Young, G.M. (Geological Society of London, 2015)Basin classification rests on a plate tectonic foundation, highlighting lithospheric substrate, proximity to plate margin and relative motion of the nearest plate boundary. Major mechanisms for regional subsidence and ...

Eriksson, Patrick George; Catuneanu, Octavian; Nelson, David R., 1951-; Rigby, Martin J.; Bandopadhyay, P.C.; Altermann, Wladyslaw, 1954- (Elsevier, 2012-05)This paper discusses geological events with an approximately global preservational scale which can aid inter-cratonic correlations and contribute to postulates of supercontinents for a set of chosen Precambrian cratons. ...

Simpson, Edward L.; Heness, Elizabeth; Bumby, Adam John; Eriksson, Patrick George; Eriksson, Kenneth A.; Hilbert-Wolf, Hannah L.; Linnevelt, Sarah; Malenda, H. Fitzgerald; Modungwa, Tshepiso; Okafor, O.J. (Elsevier, 2013-10)Early evolved microbial communities characterized the initial biological invasion of Precambrian conti-nental landscapes. In modern arid settings, microbial mats and biological soil crusts are well-developedand stabilize ...

Heness, Elizabeth; Simpson, Edward L.; Bumby, Adam John; Eriksson, Patrick George; Eriksson, Kenneth A.; Hilbert-Wolf, Hannah L.; Okafor, O.J.; Linnevelt, Sarah; Malenda, H. Fitzgerald; Modungwa, Tshepiso (Elsevier, 2014-08)Eolian ergs, and associated environs are sensitive to short- and long-term climate changes. In one of the oldest, erg deposits, the ~2.0 Ga Makgabeng Formation, facies association changes reflect one of the earliest ...

Eriksson, Patrick George; Catuneanu, Octavian; Bumby, Adam John (Elsevier, 2012-05)This work provides a pilot study of global sequence stratigraphic correlation for the Precambrian for five chosen cratons. Detailed chronostratigraphic charts summarize the supracrustal geological evolution of each craton, ...
-
Samanta, P.; Mukhopadhyay, S.; Eriksson, Patrick George (Elsevier, 2016-03)The present paper highlights the sequence development within the Mesoproterozoic Koldaha Shale Member of the Kheinjua Formation, Vindhyan Supergroup which records the occurrence of a forced regressive wedge and associated ...

Ibinoof, M.A.; Bumby, Adam John; Grantham, G.H.; Abdelrahman, E.M.; Eriksson, Patrick George; Le Roux, P.J. (Elsevier, 2016-08)Neoproterozoic, Pan-African low-grade metavolcanic rocks and associated mafic and ultramafic rocks of ophiolitic origin have long been identified within the pre-Neoproterozoic Saharan Metacraton (SMC). These low-grade ...
-
Eriksson, Patrick George; Van der Merwe, R.; Bumby, Adam John (Geological Society of South Africa, 1999)In his paper on the geometrical relations between the Transvaal Supergroup and the Bushveld Complex, Cawthorn ( 1998) argues that there is ·no need to infer a considerable period of pre-Rooiberg Group erosion prior to ...
-
Banerjee, Soumyadip; Kundu, Abhik; Eriksson, Patrick George; Sinha, Subhajit (Springer, 2021-01)The so-called mud cracks, possibly the most common deformation feature in sediment, are evident in almost all dried-up exposed sediment surfaces. Several experimental attempts have so far been made to explain the evolution ...
-
Eriksson, Patrick George; Rigby, Martin J.; Bandopadhyay, P.C.; Steenkamp, N.C. (Taylor & Francis, 2011-09)We briefly examine the possible antiquity of the supercontinental cycle while noting the likely unreliability of palaeomagnetic data >ca.1.8 Ga, assuming a gradual change from a magmatically dominated Hadean Earth to a ...
-
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 ...
-
Bordy, E.M.; Eriksson, Patrick George (Geological Society of South Africa, 2015)The Late Triassic to Early Jurassic Elliot Formation is part of the Stormberg Group (Karoo Supergroup) of South Africa. The unit is significant palaeontlologically, because it preserves not only a range of vertebrate ...

Kazmierczak, Jozef; Altermann, Wladyslaw, 1954-; Kremer, Barbara; Kempe, Stephan; Eriksson, Patrick George (Elsevier, 2009)The sparse Archean fossil record is based almost entirely on carbonaceous remnants of microorganisms cellularly preserved due to their early post-mortem silicification. Hitherto as an exception, sedimentary carbonate rocks ...

Bumby, Adam John; Eriksson, Patrick George; Catuneanu, Octavian; Nelson, David R., 1951-; Rigby, Martin J. (Elsevier, 2012-05)The Kaapvaal Craton hosts a number of Precambrian sedimentary successions which were deposited between 3105 Ma (Dominion Group) and 1700 Ma (Waterberg Group) Although younger Precambrian sedimentary sequences outcrop ...
-
Banerjee, Santanu; Jeevankumar, S.; Eriksson, Patrick George (Elsevier, 2008-04)This paper focusses upon two glauconitic sandstones in the Paleoproterozoic Deoland Formation and Chorhat Sandstone, both belonging to the Semri Group, central India. In both the cases glauconitic minerals occur in sandstones ...
