2005), named after Adak Island in the Aleutians, are also high-Mg andesites, but unlike boninites, they are very LREE enriched (normalized La/Yb > 40), contain high Sr (> 400 ppm), high Sr/Y values, low initial [sup.87]Sr/[sup.86]Sr and low ratios of radiogenic to non-radiogenic Pb.
The concentration of radiogenic [sup.40]Ar is calculated from argon isotope ratios that are measured by mass spectrometry.

The Sr, Nd, and Pb radiogenic isotopes have been used to understand magma petrogenesis and also to define the composition of basement rocks through which the magmas raised to the upper crust (Kistler and Peterman, 1973; DePaolo, 1981; Farmer and DePaolo, 1983; Faure, 2001).

Although seemingly impressed with our quality control procedures, which led us to identify biases associated with double-counting of cancer cases and an undercount in 1975, the court found fault with what the defendants cited as our failure to conduct analyses of incidence of "the types of cancers known to be radiogenic" and of cancer deaths.
Therefore, this paper summarizes the geology of the deposit, analyzes fluid inclusions (FIs), and studies C-H-O-S stable isotopes and Pb radiogenic isotopes to reveal the characteristics and evolution of the ore-forming fluids.
The careful use of radiogenic isotope geochronometers represented a significant advancement in this area and resolved the considerable speculation surrounding the petrogenesis of various deposits, including Carlin-type deposits in Nevada (Tretbar et al.
At doses near natural background radiation levels (approximating many occupational exposure situations), .the range of uncertainty in the lifetime radiogenic cancer mortality risk is large, and the lower bound of uncertainty likely includes zero (National Research Council 1990).
