Volcanology and Geotherml Energy
Bridging the gap between academic geologists and drilling engineers, Volcanology and Geothermal Energy is a practical and thorough guide to planning and operating a successful exploration project. It describes the potential geothermal reservoirs associated with volcanoes and volcanic regions and uses recent advances in volcanology to offer many examples of how geological field data give evidence of the location, nature, and size of a geothermal resource.

Engineering Geology, Second Edition
Engineering Geology introduces the fundamentals of the discipline and ensures that engineers have a clear understanding of the processes at work, and how they will impact on what is to be built. Core areas such as stratigraphy, rock types, structures and geological processes are explained, and put in context. The basics of soil mechanics and the links between groundwater conditions and underlying geology are introduced.
As well as the theoretical knowledge necessary, Professor Bell introduces the techniques that engineers will need to learn about and understand the geological conditions in which they intend to build. Site investigation techniques are detailed, and the risks and risk avoidance methods for dealing with different conditions are explained.
* Accessible introduction to geology for engineers
* Key points illustrated with diagrams and photographs
* Teaches the impact of geology on the planning and design of structures

Paleoecologists have studied the fossil record to try to clarify the relationship animals have to their environment, in part to help understand the current state of biodiversity. They have identified close links between vertebrate taxonomic and ecological diversity, that is, between the diversity of animals and the niches they occupy.

The Lost Dinosaurs of Egypt
At the bottom of the Bahariya Depression, Stromer will find the remains of four immense and entirely new dinosaurs, along with dozens of other unique specimens. But there will be reversals—shipments delayed for years by war, fossils shattered in transit, stunning personal and professional setbacks. Then, in a single cataclysmic night, all of his work will be destroyed and Ernst Stromer will slip into history and be forgotten.
The date is January 11, 2000. eighty-nine years to the day after Stromer descended into Bahariya. Another young paleontologist, Ameri-can graduate student Josh Smith, has brought a team of fellow scientists to Egypt to find Stromer’s dinosaur graveyard and resurrect the German pioneer’s legacy. After weeks of digging, often under appalling conditions, they fail utterly at rediscovering any of Stromer’s dinosaur species.
Then, just when they are about to declare defeat, Smith’s team discovers a dinosaur of such staggering immensity that it will stun the world of paleontology and make headlines around the globe.
Masterfully weaving together history, science, and human drama, The Lost Dinosaurs of Egypt is the gripping account of not one but two of the twentieth century’s great expeditions of discovery.

Banded Iron Formations from the Eastern Desert of Egypt: A new type of Ore ?
within the eastern desert of Egypt. With the exception of the southernmost deposit of Um Nar
which is suspected to be pre-Panafrican, all other BIFs are considered Neoproterozoic in age.
The iron ore occurs as rhythmically layered bands, groups of bands or separate lenses that
reach a maximum thickness of 100 m, and which are intercalated with volcanic arc assemblages
dominated by andesitic lava flows, tuffs and lapilli tuffs, and basaltic pyroclastics. In most cases,
the BIFs contain syn-sedimentary structures such as bedding and lamination. The entire
sequence of BIFs and host rocks is strongly deformed and regionally metamorphosed under
greenschist to amphibolite facies conditions.
All thirteen deposits are comprised of an oxide facies consisting of magnetite and hematite,
and a silicate facies consisting of quartz with subordinate amounts of one or more of the
minerals: chlorite (ripidolite - clinochlore), greenalite, stilpnomelane, garnet (grossular –
almandine), carbonate (mainly calcite), epidote, hornblende, or plagioclase. With the exception
of the northernmost jaspilite type deposit of Hadrabia, magnetite is the predominant oxide,
where it seems to be primary, even when martitized. Major and trace element compositions of
the Egyptian BIFs show significant variations from one deposit to another. The most intriguing
geochemical feature of the investigated BIFs is their high Fe/Si ratio in comparison with Algoma
and Superior types. Based on Fe/Si ratios, these deposits are classified into two groups; a) fresh
BIFs with Fe/Si ratio < 2.3 (e.g. Um Nar, Gebel El Hadid and Wadi El Dabbah) and b) altered BIFs
with Fe/Si ratio > 3.0 (e.g. Gebel Semna, Hadrabia and Abu Merwat).
The relatively small nature of individual deposits, strong variations in Fe2O3(t) and SiO2
contents and the enrichment in Cr, V and Ni (for a few deposits) support a volcanic exhalative
source for Fe and Si, leading most scientists to classify them as “Algoma type BIFs”. On the other
hand, the lack of sulfides, varve – like nature of some deposits, and lack of a distinct enrichment
in Co, Ni, Cu, As, and Sr are at odds with such a classification. Finally, the Neoproterozoic age of
Egyptian BIFs, high Fe and P contents, and presence of diamictites intercalated with at least one
of these deposits compels a comparison with the Rapitan type deposits.
The presence of laminations and absence of wave generated structures in most Egyptian BIFs
indicate subaqueous precipitation below wave base. The formation of authegenic primary
magnetite as the most abundant mineral instead of hematite reflects precipitation away from
the shore and under slightly euxinic conditions in basins where S and CO2 activities were low.
The paucity of primary sulfides and pure siderite in the Egyptian BIFs support this interpretation
and may also indicate formation away from the deepest parts of the basin. Accordingly, we
suggest that the Egyptian BIFs formed in the deepest “shelf – like” environments of fore-arc and
back-arc basins. These characteristics may indeed justify the definition of a new type of BIF.

An introduction to X-ray crystallography
beginning a serious study of X-ray crystallography. It will be of interest
both to those intending to become professional crystallographers and to
those physicists, chemists, biologists, geologists, metallurgists and others
who will use it as a tool in their research. All major aspects of crystallography
are covered - the geometry of crystals and their symmetry, theoretical and
practical aspects of diffracting X-rays by crystals and how the data may be
analysed to find the symmetry of the crystal and its structure. Recent
advances are fully covered, including the synchrotron as a source of X-rays,
methods of solving structures from powder data and the full range of
techniques for solving structures from single-crystal data. A suite of
computer programs is provided for carrying out many operations of
data-processing and solving crystal structures - including by direct
methods. While these are limited to two dimensions they fully illustrate the
characteristics of three-dimensional work. These programs are required for
many of the problems given at the end of each chapter but may also be used
to create new problems by which students can test themselves or each other.

physics without the separate discussion of the individual physical properties
of crystals. It may be called 'Essential Crystal Physics'.
Crystal physics is based on physics, crystallography and mathematics.
Therefore this booklet is suitable for advanced undergraduates or initial
postgraduates who are already acquainted with the elements of solid state
physics, of crystallography and of vector calculations. According to the
author's experience four-six hours are sufficient to form a true notion of
the essentials of crystal physics for non-specialists in that field.
