Chapter
Humans evolved in the dynamic landscapes of Africa under conditions of pronounced climatic, geological and environmental change during the past 7 million years. This book brings together detailed records of the paleontological and archaeological sites in Africa that provide the basic evidence for understanding the environments in which we evolved....

In the broader Caucasus region, multiple extrusive volcanic units are present within the Jurassic, Cretaceous, Eocene and Miocene sedimentary successions. Partial reworking of volcanic material from various provenance areas into Eocene, Oligocene and Miocene reservoir units is commonly observed in the Eastern Black Sea and in the Rioni, Kartli and...
Conference Paper
The alkali/mineral reactions in Nordhorn sandstone, dolomite and reservoir sandstones from the Vienna Basin have been analysed by static tests using steel autoclaves and plastic bottles to gain first insights into potential dissolution and precipitation within the reservoir during alkali-polymer flooding. The interaction of the rocks with NaOH, KOH...

The Horn of Africa is yields famous Miocene to Pleistocene fossil sites including hominid remains. The fossiliferous sediments were deposited in fluvio-deltaic to lacustrine environments. The basin development is mainly controlled by the tectonic development of the Afar Depression. The Galili research area represents a new fossil site in the southe...
Conference Paper
Analyses of the isotope ratios of naturally existing materials have increasingly been used to reconstruct paleoenvironmental and paleoclimatic conditions. In this study carbon (C) and oxygen (O) isotopic composition of bioapatite from fossil tooth enamel is used to reconstruct Pliocene environmental and climatic changes at Galili, in the Awash vall...
Conference Paper
The pre-Neogene basement of the Vienna Basin comprises, among others, the late Triassic Hauptdolomit, which serves as a gas reservoir below the Neogene silicilastic sediments. Both Alpine nappe stacking and the formation of the pull-apart basin in the Miocene affected this rock after its deposition. This polyphase deformation resulted in the genera...
Article
In porous sedimentary rocks, fault zones are frequently accompanied by deformation bands. These structures are tabular zones of displacement, where grain rotation and in some cases grain fracturing result in a significant reduction in porosity. Core samples were analyzed close to large normal faults from the most productive hydrocarbon reservoir in...

The early Pliocene locality Galili in the southern Afar depression (Somali Region, Ethiopia) yields fossil suid and elephantoid remains from the Lasdanan, Dhidinley, Godiray, and Shabeley Laag Members in the Mount Galili Formation. The early Pliocene Galili faunal assemblage, including hominid fossils, comes from a crucial time span of early homini...

The sediments of Charkadio Cave (Island of Tilos) have been object of chemical and mineralogical investigation. Sampling the speleothems of Charkadio Cave, it is possible to look back into the island’s younger geological history. Tilos is of non-volcanic origin but neighbored to several volcanoes of the Aegean (Kos, Nisyros, and Giali). We observed...

Research of the international PAR (PaleoAnthropological Research) team under the leadership of the Institute for Anthropology, University of Vienna, started in 2000 and will be continued over the next years in the southern Afar Depression of Ethiopia. The Pliocene sedimentary succession represents the eastern rift shoulder of the northernmost Quart...
