Research on the Precambrian basement of North America over the past two decades has shown that Archean and earliest Proterozoic evolution culminated in suturing of Archean cratonic elements and pre-1.80-Ga Proterozoic terranes to form the Canadian Sh

A framework geophysical program in southeastern Nebraska during 1970 identified a near-circular feature having gravity relief of about 8 mgal and a magnetic anomaly of about 800 gammas. Analysis of the geophysical data provided a model of a cylindric

A variety of data have been compiled in eastern Nebraska and adjacent areas that are pertinent to understanding the complex Precambrian history of the Midcontinent USA. Petrographie analysis has been done for samples from wells penetrating the Precam

The Kern Mountains plutonic complex is composed of multiple intrusions referred as the Cove, Tungstonia and Hoodoo Canyon plutons, whose emplacement was structurally controlled. The plutons are members of the calc-alcaline granite series, leucogranit

Four conventional K/Ar ages were determined on two samples from each of DVDP drillholes 1 and 2. Apparent ages (calculated using the new 1977 calibration constants) range from 1.21±0.11 m.y. to 1.34±0.23 m.y. for samples from 25.52m and 148.81m dep

During the last several years volcanic rocks from the Ross Island, Marguerite Bay, and Mt. Weaver areas have been studied. Field data and some laboratory work indicate that the portions of the Ross Island area already studied consist of an older oliv

A study was made of the heavy minerals in strata in the Lucero uplift, with special reference to the pre-Morrison Jurassic rocks. Zircon, garnet, tourmaline, rutile, and several opaque minerals are dominant; epidote, biotite, staurolite, and apatite
