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.
These are all research topics that collectively underscore the fundamental utility of the Ar data are acquired, modeled, and/or interpreted.
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.
Stores and retailers behaved in a similar manner, purchasing hundreds and in some cases thousands of semi-automatic and military-style rifles in case a limit was introduced by the new commander-in-chief.
The popularity of the gun seems to lie in how easy it is to use and the cost, with the price tag of many AR-15s leading to many people trying to build their own rather than purchase the weapon from a retailer.'Ruger is a company that was founded on the idea of providing the average Joe with quality firearms at fair prices,' reads a review of the firearm in American Rifleman.
The weapons can be outfitted with bump stocks, which was used in the Las Vegas attack in October, but the one Kelly had in his possession was not modified with such a device according tom officials.
