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 ...

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 ...

The Sistan region in southeast Iran is considered as one of the most active dust source regions in South west Asia. The strong ‘‘Levar’’ winds in summer favor the uplift of large quantities of dust from the Hamoun basin, ...

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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

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 ...
