Studies on the sequence stratigraphic features of carbonate weathered residuum reveal that the key factor which makes the karstification possible is the permeability paths that occurred, controlled by ...

Sequence stratigraphy is a relatively new branch of geology that attempts to link prehistoric sea-level changes to sedimentary deposits. The 'sequence' part of the name refers to cyclic sedimentary ...

Note: I'm traveling this week and decided to rerun a post I wrote nearly four years ago. I've edited a little bit so hopefully those who remember reading it the first time get something out of it ...

The depositional environment of the Upper Ordovician Harding Sandstone of central Colorado has been debated since Charles Walcott first described its pteraspidomorph agnathans. Although most previous ...

This post reviews some fundamental concepts of stratigraphy that are discussed in a 1964 GSA Bulletin paper by Harry Wheeler. At the same time, it is an essay about my own quest to really understand ...

The Carboniferous period is pivotal in the geological record, marked by intricate stratigraphic sequences and diverse microfossil assemblages that reveal past environmental conditions and tectonic ...

The Lowermost Cretaceous Fahliyan formation is an important carbonate reservoir in the Persian Gulf and the onshore oil fields of Southwest Iran (Fig. 1). The Fahliyan formation in Darkhowain field ...

RIYADH — The Saudi Geological Survey (SGS) has launched, with the approval of the Saudi Stratigraphic Committee, a unified geological diagram for sedimentary sequences in the Kingdom. This contributes ...

After 40 years of exploration, large-scale structural reservoirs have become more difficult to find in Kazakhstan's South Turgay basin. China National Petroleum Corp. (CNPC) has increased its reserves ...

The Tentative Lists of States Parties are published by the World Heritage Centre at its website and/or in working documents in order to ensure transparency, access to information and to facilitate ...
