Reviews in Mineralogy and Geochemistry. 52:631-656
The various methods of geochronology have, as a rule, evolved along a characteristic path whereby the earliest work lays out the physical and mathematical foundation and demonstrates its practicality for a few cases using optimal samples. Later work

Early Precambrian Basic Magmatism ISBN: 9789401066662
Early Precambrian basic rocks occur throughout a large part of the USA (Peterman, 1979; Harrison and Peterman, 1984). Archaean complexes outcrop in two major provinces, one forming the southwestern tip of the Superior Province in northern Minnesota a
