E. A. Du Bray, L.W. Snee
2002, Professional Paper 1657
Cretaceous intrusions hosted by the Proterozoic Newland Formation. The northern intrusion, centered on Boulder Baldy, consists of outer, intermediate, and core zones composed of aegirine-augite quartz monzonite, hornblende quartz monzodiorite, and biotite granodiorite, respectively.

Characterization and modes of occurrence of elements in feed coal and fly ash; an integrated approach
Michael E. Brownfield
2002, Fact Sheet 038-02
Despite certain environmental concerns, coal is likely to remain an important component of the United States energy supply, partly because it is the most abundant domestically available fossil fuel. One of the concerns about coal combustion for electricity production is the potential release of elements from coal and coal combustion...

Progress on geoenvironmental models for selected mineral deposit types
Robert R. Seal, II, Nora K. Foley, editor(s)
2002, Open-File Report 2002-195
Since the beginning of economic geology as a subdiscipline of the geological sciences, economic geologists have tended to classify mineral deposits on the basis of geological, mineralogical, and geochemical criteria, in efforts to systematize our understanding of mineral deposits as an aid to exploration. These efforts have led to classifications...
