OCR: Geochemical Database for the Boulder Batholith and Its Satellitic Plutons, Southwest Montana Geochemical data presented in this report pertain to Cretaceous igneous intrusions of the Boulder batholith and its satellitic plutons in southwest Montana. The Requires Adobe Acrobat 7 geographic area addressed in this compilation is approximately bounded by lats 45.6º and 46.7º N. and longs 112.75º and Windows System Requirements 111.5º W. These data were compiled in order to establish the Intel® Pentium® processor, Microsoft® geologic framework for world-class mineral deposits of the Windows® 2000 with Service Pack 2, Windows Butte district. Although these deposits and their host rocks XP Professional or Home Edition, or Windows have been the subject of many investigations, the petrologic XP Tablet PC Edition characteristics of associated intrusive rocks have not been systematically compiled, synthesized, or interpreted. Macintosh System Requirements Abundant late Mesozoic intrusions in the study area are probably byproducts of subduction-related processes, PowerPC® G3 or later, Mac OS X v.10.2.8 or later including back-arc magmatism that prevailed along the west edge of the North American plate during this interval. The To get started, install Acrobat Reader provided ultimate goal of this effort will be an evaluation of the on the disk, if necessary, then double-click on time-space-compositional evolution of Mesozoic the icon for DS454.pdf.
