The sturdy binding and high-quality printing of the book are typical of what readers have come to expect from The Geological Society book series.
The section on methodological developments represents the core of the book’s new “advances” in Ar methods.
This section includes topical discussions on the uncertainties in quantifying K-decay, what does and does not qualify as a neutron flux monitor, the status of thermal histories modeled from laboratory degassing of argon in K-feldspar and white mica, new data on argon diffusion and solubility in plagioclase, effects of argon recoil and alteration, and details of a laser heating method.
The microtextural environment seems to control the K-Ar age variations of illite-fractions of different sizes.
Thin, uncompacted, and radial coatings are 200 Ma old, whereas uncompacted fibrous laths filling enlarged secondary porosity are 180 Ma old, and compacted or recrystallized tangential particles yield intermediate or even younger ages.
I suppose this will be the last time I have it on - for a while at least.
The Texas man who killed 26 people and left many more injured after he opened fire in the middle of a church service on Sunday used a Ruger AR-556 to carry out the senseless massacre.
As stated by the editors in their introduction, these chapters were assembled with the goal of providing technique-specific examples highlighting recent advances in the field of Ar geochronology offers much to the interested reader.
The book is organized into four sections: methodological developments, tectonics, volcanology, and planetary sciences.
Although several of the chapters would have been improved by inclusion of summary data tables and better attention to the font size in some figures, the overall editorial quality of the chapters is quite good.
For the most part enough novel material in this book makes it a useful reference.
The tectonics section contains contributions that provide new data and insight into Ar data in different geographic areas, as is mostly done in the two chapters comprising the volcanology section.
