International conference on terrain and geohazard challenges facing onshore oil and gas pipelines : Evaluation, routing, resign, construction, operation ; Proceedings of a three day international conference on terrain and geohazard challenges facing onshore oil and gas pipelines, organised by the Institution of Civil Engineers in association with BP Exploration and held at the Institution of Civil Engineers, London, UK, on 2 – 4 June 2004
To access global oil and gas deposits, major pipelines must traverse remote regions with extreme terrains. There are a significant number of pipeline projects, active or planned, in tropical jungles, mountains and deserts, in permafrost and in areas of wetland. Each of these natural environments is associated with a range of geohazards, which may include landslides, soil erosion, karst, river migration, and seismic or volcanic activity. At the same time, society demands increasing availability and reliability of supply, together with improved environmental standards, all making for substantial challenges.
Geological atlas of Africa : With notes on stratigraphy, tectonics, economic geology, geohazards, geosites and geoscientific education of each country
Here is the new edition of the first attempt to summarize the geology of Africa by presenting it in an atlas and to synthesize the stratigraphy, tectonics, economic geology, geohazards and geosites of each country and territory of the continent. Furthermore, the digitized geological maps are correlated and harmonized according to the current stratigraphic timetable. The atlas aims to contribute to capacity building in African Earth Sciences and to aid the initiation of research and enable the achievement of economic opportunities by providing a database of basic geological background information.
Geological atlas of Africa : With notes on stratigraphy, tectonics, economic geology, geohazards, geosites and geoscientific education of each country
T is atlas is intended primarily for anybody who is in-some background for the arrangement of how the terested in basic geology of Africa. Its originality lies atlas was done. T e second chapter is devoted to the in the fact that the regional geology of each African history of geological mapping in Africa, necessary nation or territory is reviewed country-wise by maps for a fuller appreciation of why this work in Africa is and text, a view normally not presented in textbooks worth doing. Chapter 3 provides an executive s- of regional geology. It is my belief, that there has long mary on the stratigraphy and tectonics of Africa as a been a need in universities and geological surveys, whole, i. e. in the context of no political boundaries.
