Book Description
The little-known history of how the Sahara was transformed from a green and fertile land into the largest hot desert in the world The Sahara is the largest hot desert in the world, equal in size to China or the United States. Yet, this arid expanse was once a verdant, pleasant land, fed by rivers and lakes. The Sahara sustained abundant plant and animal life, such as Nile perch, turtles, crocodiles, and hippos, and attracted prehistoric hunters and herders. What transformed this land of lakes into a sea of sands? When the Sahara Was Green describes the remarkable history of Earth’s greatest desert—including why its climate changed, the impact this had on human populations, and how scientists uncovered the evidence for these extraordinary events. From the Sahara’s origins as savanna woodland and grassland to its current arid incarnation, Martin Williams takes us on a vivid journey through time. He describes how the desert’s ancient rocks were first fashioned, how dinosaurs roamed freely across the land, and how it was later covered in tall trees. Along the way, Williams addresses many questions: Why was the Sahara previously much wetter, and will it be so again? Did humans contribute to its desertification? What was the impact of extreme climatic episodes—such as prolonged droughts—upon the Sahara’s geology, ecology, and inhabitants? Williams also shows how plants, animals, and humans have adapted to the Sahara and what lessons we might learn for living in harmony with the harshest, driest conditions in an ever-changing global environment. A valuable look at how an iconic region has changed over millions of years, When the Sahara Was Green reveals the desert’s surprising past to reflect on its present, as well as its possible future.

Book Description
Of all the states of the Middle East and North Africa, Libya has long been the country about which the least is known. It is only in recent times that scholars and the general public alike have begun to appreciate the complexity of Libya's turbulent history including the recent February 17th Revolution in 2011 when protests broke out throughout Libya, demanding better living conditions and more job opportunities. When the Qaddafi regime responded with force, killing scores of unarmed civilians, the protesters called for regime change. In what came to be known as the February 17th Revolution, the Qaddafi regime was overthrown and Qaddafi was killed in October 2011. In July 2012, the Libyan people elected a General National Congress charged with overseeing the drafting of a new constitution and the election of a national government. This fifth edition of Historical Dictionary of Libya covers its history through a chronology, an introductory essay, appendixes, and an extensive bibliography. The dictionary section has over 400 cross-referenced entries on important personalities, politics, economy, society, conflicts, and the culture of Libya. This book is an excellent access point for students, researchers, and anyone wanting to know more about Libya.

Book Description
In this book, the author describes in simple, non-technical terms the adventures he has experienced during his work as an earth scientist in some of the remote parts of the arid and semi-arid world. His aim in writing this concise account of some of the work he has been involved in over the past fifty years is to try to convey to the non-specialist some of the excitement and fun involved in fieldwork in the drier regions of the world. His studies of the soils, landforms and the recent geological history of arid and semi-arid regions have taken Martin Williams to some remarkable places in Africa, Asia, Australia and the Middle East. Not only are the landscapes themselves often stunningly beautiful, but the contact with people from quite different backgrounds and cultures has been an enriching experience. His work has taken him to places far off the beaten track, whether it be the rugged mountains of Ethiopia and northern China, the sandy deserts of the Sahara and Rajasthan, or the great river valleys of Somalia, central India and the Nile. The chapters that follow are not intended to form a coherent chronological narrative, although they do appear in rough chronological order. They should rather be viewed as vignettes or brief evocative descriptions, much as in the discursive tradition of the wandering Irish storytellers. Acting on the principle that it is not necessary to be solemn to be serious, the author aims to entertain as well as to instruct.

Book Description
The Murzuq Basin is a large intracratonic sag basin located in southwestern Libya. Exploration efforts started in this vast and remote Saharan region already in 1957 and 60 exploratory wells have been drilled to date, resulting in over 20 discoveries with around 4,000 million barrels of oil in place. Most discoveries have been made in Ordovician sandstone reservoirs sourced by hot shales of the Lower Silurian Tanezzuft Formation. Oil is already being produced and exported from the area, but the basin's total hydrocarbon potential is still poorly understood. Recent exploration - especially the major discovery and initial development of the Giant "Elephant" Field - has greatly increased interest for the area's potential. Many petroleum geologists and companies now believe that the basin may well develop into a new major hydrocarbon province which will significantly contribute to Europe's energy needs in the next decades. This book presents papers from a conference held at Sebha University - on the eastern margins of the Murzug Basin - in September 1998.The book continues an ongoing series of presentations of the geology of Libya, but the 25 contributions herein mostly centre on the Murzuq Basin itself and on nearby areas. There are still many unresolved questions in terms of geological and hydrocarbon exploration in these difficult desert areas, but the papers herein will hopefully present a first comprehensive overview of an exciting frontier exploration region. About half of the papers are directly related to hydrocarbon exploration, and to source rock and reservoir development, but a wide variety of other features are also described, ranging from palaeontology and biostratigraphy to ore geology and water resources, covering the entire geological column from the Precambrian to the Holocene. The book concludes with a bibliography covering all geological aspects of this challenging but very promising frontier area.

Book Description
Libya has the largest petroleum reserves of any country in Africa and since production began in 1961 over 20 billion barrels of oil have been produced. Libya is scheduled to reach the mid-point of depletion of reserves in 2001 and this provides a timely point at which to review the state of petroleum exploration in Libya.A large amount of data has been published on the geology of Libya, but it is scattered through the literature; much of the older data has been superceded, and several of the key publications, especially those published in Libya, are difficult to find. This book represents the first attempt to produce a comprehensive synthesis of the petroleum geology of Libya. It is based exclusively on published data, supplemented by the author's experience gained during ten years work in Libya. The aim of the book is to systematically review the plate tectonics, structural evolution, stratigraphy, geochemistry, and petroleum systems of Libya, and provides valuable new data on fields, production, and reserves. This volume will provide a ready source of reference to individuals and companies who wish to obtain an overview of the petroleum geology of Libya, and will save them the laborious task of sifting through hundreds of publications to find the data they require. The book includes 148 newly drawn figures.
