This work takes a critical look at the current concept of isotopic
landscapes ("isoscapes") in bioarchaeology and its application in
future research. It specifically addresses the research potential
of cremated finds, a somewhat neglected bioarchaeological
substrate, resulting primarily from the inherent osteological
challenges and complex mineralogy associated with it. In addition,
for the first time data mining methods are applied. The chapters
are the outcome of an international workshop sponsored by the
German Science Foundation and the Centre of Advanced Studies at the
Ludwig-Maximilian-University in Munich. Isotopic landscapes are
indispensable tracers for the monitoring of the flow of matter
through geo/ecological systems since they comprise existing
temporally and spatially defined stable isotopic patterns found in
geological and ecological samples. Analyses of stable isotopes of
the elements nitrogen, carbon, oxygen, strontium, and lead are
routinely utilized in bioarchaeology to reconstruct biodiversity,
palaeodiet, palaeoecology, palaeoclimate, migration and trade. The
interpretive power of stable isotopic ratios depends not only on
firm, testable hypotheses, but most importantly on the cooperative
networking of scientists from both natural and social sciences.
Application of multi-isotopic tracers generates isotopic patterns
with multiple dimensions, which accurately characterize a find, but
can only be interpreted by use of modern data mining methods.

This book investigates the Upper Silesian Coal Basin (USCB), one of
the oldest and largest mining areas not only in Poland but also in
Europe. Using uniform research methods for the whole study area, it
also provides a summary of the landscape transformations. Intensive
extraction of hard coal, zinc and lead ores, stowing sands and rock
resources have caused such extensive transformations of landscape
that it can be considered a model anthropogenic relief. The book
has three main focuses: 1) Identifying anthropogenic forms of
relief related to mining activity and presenting them from a
spatial, genetic and age perspective; 2) Determining the changes in
the morphometric characteristics of relief and the conditions for
matter circulation in open systems (drainage basins) and closed
systems (land-locked basins) caused by the extraction of mineral
resources; and 3) Estimating the extent of anthropogenic denudation
using two different methods based on raw-material output and
morphometric analysis. In Poland, no other mining area has
undergone such intensive mining activity as the Upper Silesian Coal
Basin during the last half century. Its share in the total
extraction of mineral resources was as high as 32%. The total
extraction of hard coal in the Upper Silesian Coal Basin from the
mid-18th century until 2009 was the sixth largest in the world, and
the permanent, regional effects of mining anthropopressure on the
relief are among the most severe in the world. The anthropogenic
denudation rate in the Upper Silesian Coal Basin, as well as the
Ruhr Coal Basin (Ruhr District) and the Ostrava-Karvina Coal Basin,
ranges from several dozen up to several hundred times higher than
the rate of natural denudation, irrespective of the calculation
method used. It would take the natural denudation processes tens of
thousands of years to remove the same amount of material from the
substratum as that removed through human mining activity.
Step-by-step Q&As with detailed colour photographs for easy
identification. The Firefly Guide to Minerals, Rocks & Gems is
designed for easy and reliable identification of minerals, gems and
rocks. Beginning with the stone's colour and any streak, and using
a sequence of straightforward questions and answers - aided by
1,300 photographs and drawings - it's easy to narrow down the
possibilities among 350 minerals, gems and rocks to the conclusive
classification. The book organizes the rocks by colour: Blue, Red,
Yellow, Brown, Green, Black, and White. Identification begins with
noting the colour of the rock's streak (i.e., vein, line).
Identification is then further narrowed down with respect to
Colour, Crystal form, Hardness, Lustre, Density, Cleavage, Break
and Tenacity. Each rock's main photograph shows the general or
typical view, and identification tips about features are noted in
the margins of the respective page. Similar stones are presented
for comparison and tips are provided that can eliminate imposters.
Drawings show the mineral's crystal shape. The chemical formula
reveals the elements from which the mineral is composed. There is
also information about where the stone is typically found and some
of the ways that humans have utilized it. Packed with beautiful
photographs of earth's many rocks, minerals and gems, The Firefly
Guide to Minerals, Rocks & Gems is perfect for amateur
mineralogists and collectors.
Of huge relevance in a number of fields, this is a survey of the
different processes of soil clay mineral formation and the
consequences of these processes concerning the soil ecosystem,
especially plant and mineral. Two independent systems form soil
materials. The first is the interaction of rocks and water,
unstable minerals adjusting to surface conditions. The second is
the interaction of the biosphere with clays in the upper parts of
alteration profiles.
