Aug 1, 2015 · Since 2003, a geologist (Asfawossen Asrat, author of this contribution) from the School of Earth Sciences, Addis Ababa University and speleologists from CIRS, Ragussa, Italy explored the limestone terrains of Tigray, the Blue Nile gorge and Southeastern Ethiopia and discovered many cave entrances, mostly in the Mechara karst system (Baker et al ...

Jan 1, 1973 · Despite the high geoheritage value of caves and karsts, northern Ethiopia’s largest cave at Zeyi (13.5586°N, 39.1454°E) in the Dogu’a Tembien district has received little attention so far. We...

The Achere cave forms part of the bigger Achere-Aynage cave system and has been previously described (Asrat et al., , 2008. The Achere-Aynage cave system developed along numerous NE-SW...

In 2007, 2008 our survey documented twenty-one cave sites and shelters with evidence of cultural deposits, including Middle Stone Age (MSA) and Later Stone Age (LSA) stone artifacts, faunal remains, and rock art.

Asfawossen Asrat Kassaye is Professor of Geology at the School of Earth Sciences at Addis Ababa University (AAU). ... in 2002. Current research projects include “Speleothem Pa-laeoclimatology”, “Historical Climatology”, “Cave Geoarchaeology”, “Paleo-Lakes and Hominin Sites”, and “Geoheritage, Geodiversity and Geoconservation ...

Sep 27, 2002 · Ethiopia is endowed with many rock-hewn churches, with the largest group in central and eastern Tigrai. These churches can be divided into four zones: the Atsbi, Hawzen-Ger'alta, Sinkata-Adigrat, and Tembien, with more than 100 rock-hewn churches of different ages, sizes, and histories.

Dec 18, 2006 · Our results can be widely applied to speleothem studies distinguishing the relative importance of the various proxies in recording cave ‘external’ (climate, hydrology) and cave ‘internal’ (e.g. evaporation) processes.

Asrat quarry, Shashamane, West Arsi Zone, Oromia Region, Ethiopia : Trachyte. 1,970 meters elevation Calcite speleothems occur in a faultline cave (one of many related to formation of the East African Rift Valley).

Aug 1, 2015 · Most of the cave systems in the region developed along major NE–SW aligned rift passages, parallel to the general orientation of the Main Ethiopian Rift, suggesting karstification triggered by rift-related extensional tectonics (Asrat et al., 2008).

His current projects include ‘Speleothem Palaeoclimatology’, ‘Historical Climatology’, ‘Cave Geoarchaeology’, ‘Paleo-Lakes and Hominin Sites’, ‘Geoheritage, Geodiversity and Geoconservation’ and ‘Harmonization of the Geological maps of Ethiopia’.
