Book Description
This bibliography on the water and geological information or Liberia was begun in 1995 as a request through the US Department or State by the Government or Liberia. It brings together selected citations from a variety of different cartographic, geographical, geological and hydrological resources and specialized library collections. Most of the citations have location information on where these items can be located and used on site, and either borrowed through inter-library loan or purchased through a commercial document delivery services.

Book Description
The Sahara-Sahel borderland occupies a critical geographical position due to its recurrent latitudinal shifts, continually having a strong impact on humans, animals and plants. Gobero is located at the southern limits of the present Sahara, in Niger. The archaeological record at this site encompasses the re-occupation of the Sahara ca 10,000 years ago until approximately 2000 years ago. During this long period, Gobero witnessed significant fluctuations in climate and water resource availability that resulted in cycles of human occupation, abandonment and re-occupation around a natural basin occupied by a palaeolake, until desertification became an irreversible process and the area turned into a no-return frontier for its occupants. This book presents the archaeological, anthropological and environmental data collected during the 2005 and 2006 field seasons at Gobero. Various factors highlight the extraordinary significance of this site. Thanks to its geographical position, straddling the ancient shifting border(s) of the Sahara and the Sahel, the Gobero's archaeological record reveals critical population movements in this part of Africa and different economic and technological strategies its inhabitants employed to adapt to changing environmental conditions. The presence of both settlement and burial features at Gobero gives a comprehensive view of the cultural, social, economic and funerary traditions of the people who lived and died at this site during almost the entire Holocene. The results from these archaeological investigations provide a term of reference for future research and interpretations of past human occupations in the Sahara, as well as North and West Africa.
Geology of Southwest Gondwana
Author: Siegfried SiegesmundPublisher: Springer
ISBN: 3319689207
Category : Science
Languages : en
Pages : 700
Book Description
This book focuses on the geological evolution of Southwest (SW) Gondwana and presents state-of-the-art insights into its evolution. It addresses the diachronic assembly of continental fragments derived from the break-up of the Rodinia supercontinent later amalgamated to build SW Gondwana during the Neoproterozoic–Cambrian transition, which on a global scale includes parts of present-day South America, Africa and Madagascar. The book presents 24 state-of-the-art reviews including the most crucial controversies. Most experienced scientists about the geology of SW Gondwana from Europe, Africa, South America and Australia present contributions on key areas addressing the interactions between the main cratons and fold belts on both sides of the South Atlantic Ocean. Chapters related to the geology of the major Archean- Paleoproterozoic cratons and Neoproterozoic Brasiliano/Pan-African fold belts enable readers to gain an in-depth understanding of the tectonometamorphic and magmatic evolution of SW Gondwana. The book covers a wide range of issues including metallogenetic, sedimentary, paleobiological and paleoclimatic processes and allows a deep insight into this key period of the Earth’s evolution.
