Petrographic classifications of sand and sandstone proposed more than half a century ago
are still in use, although they were formulated at a time when depositional and post …

The classical approach to sandstone petrology, established in the golden years of plate
tectonics and based on the axiom that “detrital modes of sandstone suites primarily reflect …

Variations in continental volcanic arc emissions have the potential to control atmospheric
carbon dioxide (CO2) levels and climate change on multimillion-year time scales. Here we …

In the last two centuries, since the dawn of modern geology, heavy minerals have been used
to investigate sediment provenance and for many other scientific or practical applications …

We often resort to mythical thinking in the face of natural phenomena that we hardly
understand. Sedimentary petrology has several long-standing myths. One is that sediments …

Geochemical parameters obtained from the analysis of sediments and sedimentary rocks
are widely used to infer weathering and paleo-weathering conditions in source areas …

Silicate weathering is critical to global carbon cycle and climate change, and has attracted
considerable attention in Earth science studies. Chemical weathering intensity evaluation …

This study presents an integrated mineralogical–geochemical database on fine-grained
sediments transported by all major rivers of southern Africa, including the Zambezi …

Although the proxies based on elemental geochemistry of siliciclastic sediments have been
well developed to indicate the intensity of chemical weathering in various catchments, their …

Sediment in coastal N amibia to southern Angola is supplied dominantly from the Orange
River with minor additional fluvial input and negligible modifications by chemical processes …
