While extreme rainfall events may provide rare opportunities for replenishment of surface
water and groundwater resources in vulnerable (semi) arid areas, they are typically also …

Globally many valuable karst resources are under severe threat due to anthropogenic
activities. This paper presents a review of the geomorphology of karst landforms including …

Abstract The Transvaal Supergroup, on the Kaapvaal Craton in South Africa, is widely
accepted as one of the best-preserved sedimentary archives to constrain planetary-scale …

Trace and rare earth elements (REEs) are considered to be reliable indicators of chemical
processes for the evolution of carbonate systems. One of the best examples of ancient …

The early Toarcian, as registered in a variety of sedimentary archives, was characterized by
an abrupt negative carbon-isotope excursion (CIE) typically superimposed on a long-term …

Marinoan cap carbonates are the first sedimentary rocks deposited after the Marinoan
Snowball Earth glaciation and likely record the marine geochemical signals across the …

Several lithostratigraphic and radiometric-dating studies over the last half century have
generated a robust stratigraphic data set about the Transvaal Supergroup sedimentary …

The stratigraphic correlation of the ca. 2353±18 Ma to 2316±7 Ma Duitschland and
Rooihoogte formations, Transvaal Supergroup, South Africa, becomes critically important …

Oxygen availability is crucial for the evolution of eukaryotes in geological history, yet
detailed Mesoproterozoic oceanic-atmospheric redox conditions remain enigmatic. In …

Aptian is characterized by widespread deposition of organic-rich sediment. The Aptian
bitumen limestone horizon, which is thin decimetre-thick sequences, locally crops out in the …
