This wide-ranging discussion of Precambrian rocks includes contributions from a diverse array of authors actively engaged in investigations of various aspects of U.S.

Precambrian geology. Summary discussions by the editors of the five major chapters place these contributions in a. The youngest rocks of the Precambrian, the Keweenawan, are principally lava flows and conglomerates with minor slates and sandstones.

Figure 2 shows their location. They contain Michigan's native copper. The Keweenawan formations have suffered less folding and erosion, thus their record is more complete and their geology better known.

Precambrian rocks are exposed in numerous areas in the Rocky Mountain region, mostly in the cores of up­ lifted mountain blocks (fig. The rocks range from unmetamorphosed late Proterozoic sedimentary rocks to Archean gneisses.

With a focus on process-oriented and comparative studies, it covers, but is not restricted to, subjects such as: (1) Chemical, biological, biochemical and cosmochemical evolution; the origin of life; the evolution of the oceans and.
