Earliest Life on Earth: Habitats, Environments and Methods of Detection (Hardcover, 2011 Ed.): Suzanne D. Golding, Miryam... Earliest Life on Earth: Habitats, Environments and Methods of Detection (Hardcover, 2011 Ed.)

This volume integrates the latest findings on earliest life forms, identified and characterised in some of the oldest rocks on Earth. New material from prominent researchers in the field is presented and evaluated in the context of previous work. Emphasis is placed on the integration of analytical methods with observational techniques and experimental simulations. The opening section focuses on submarine hot springs that the majority of researchers postulates served as the cradle of life on Earth. In subsequent sections, evidence for life in strongly metamorphosed rocks such as those in Greenland is evaluated and early ecosystems identified in the well preserved Barberton and Pilbara successions in Southern Africa and Western Australia. The final section includes a number of contributions from authors with alternate perspectives on the evidence and record of early life on Earth. Audience This volume will be valuable to researchers and graduate students in biogeosciences, geochemistry, paleontology and geology interested in the origin of life on earth.

Coalbed Methane: Scientific, Environmental and Economic Evaluation (Hardcover, illustrated edition): M. Mastalerz, M.V.... Coalbed Methane: Scientific, Environmental and Economic Evaluation (Hardcover, illustrated edition)

Coalbed gas has been considered a hazard since the early 19th century when the first mine gas explosions occurred in the United States in 1810 and France in 1845. In eastern Australia methane-related mine disasters occurred late in the 19th century with hundreds of lives lost in New South Wales, and as recently as 1995 in Queensland's Bowen Basin. Ventilation and gas drainage technologies are now in practice. However, coalbed methane recently is becoming more recognized as a potential source of energy; rather than emitting this gas to the atmosphere during drainage of gassy mines it can be captured and utilized. Both economic and environmental concerns have sparked this impetus to capture coalbed methane. The number of methane utilization projects has increased in the United States in recent years as a result, to a large extent, of development in technology in methane recovery from coal seams. Between 1994 and 1997, the number of mines in Alabama, Colorado, Ohio, Pennsylvania, Virginia, and West Virginia recovering and utilizing methane increased from 1 0 to 17. The Environmental Protection Agency estimates that close to 49 billion cubic feet (Bet) of methane was recovered in 1996, meaning that this amount was not released into the atmosphere. It is estimated that in the same year total emissions of methane equaled 45. 7 Bcf. Other coal mines are being investigated at present, many ofwhich appear to be promising for the development of cost-effective gas recovery.

R2,438 R1,928 Discovery Miles 19 280 Save R510 (21%) Out of stock

This book explains how and where copper and fossil fuels were formed and the likely future for the extraction of copper and coal. The colourful chronology of our efforts to extract metals from minerals and energy from fossil fuels is presented from earliest times until the present day. The difficult concept of human sustainability is examined in the context of continually decreasing real prices of energy and metals. This book integrates the latest findings on our historic use of technology to continually produce cheaper metals even though ore grades have been decreasing. Furthermore, it shows that the rate of technological improvement must increase if metals are to be produced even more cheaply in the future.
