Introduction

Abstract

Abstract This bibliography is an attempt to bring together as many of the stuaies dealing with the Precambrian geochronology of North America as possible, and to provide a short summary of each study. Journal articles, symposium and conference papers, abstracts, and those Ph.D. theses found in Dissertation Abstracts International covering the period 1951 through 1977 are included. The summaries are designed to give a review of the results of each study. They are not intended to serve as substitutes for the original papers. For this reason changes in decay constants, errors in measurements and ages, analytical techniques, and sections of papers dealing with subjects other than geochronology have been largely ignored. Workers who wish to adjust ages to conform to decay constants currently in use will find the values of those constants in Steiger, R. K, and Jager, E., 1977, Subcommission on Geochronology: Convention on the Use of Decay Constants in Geo- and Cosmochronology: Earth and Planetary Science Letters, v. 36, p. 359–362. Structural, petrological, paleomagnetic, and stratigraphie data have beer, included only to clarify geocnronolooical results. This bibliography was conceived as a source to which a worker could turn to find geochronological studies relevant to a particular area. Studies dealing soleiy with refinements in decay constants, improvements in analytical or mathematical techniques, and laboratory studies of the behavior of isotope systems under conditions approximating metamorphic environmtints have not been included. Abstracts reporting preliminary results have been included if the full-length paper was published at least one year later.
