A theoretical piezomagnetic field is calculated as a function of time and ground position for an earthquake instability model applied to moderate (M ∼ 6) earthquakes on the San Andreas fault near Parkfield, California. The instability model simulat

An analytical solution is obtained for the piezomagnetic field generated by a single screw dislocation and its image, representing an infinitely long vertical fault with uniform strike slip that cuts the upper or lower portion of a half-space. The so

U-Pb isotopic analyses of cogenetic zircon fractions from four granitic bodies in northeastern Wisconsin yielded the following concordia intercept ages: Amberg Granite and Newingham Granodiorite, $1,860 \pm 15 m.y.$; Hoskin Lake Granite, $1,890 \pm 1

A foliated granitic complex in the north evolved contemporaneously with gneiss in the south. Small ultramafic bodies in both areas were emplaced before and after metamorphism. All are cut by younger dolerite dikes. K-Ar dates in the gneiss and granit

U-Pb isotopic analyses of zircons from two granodiorites of the Abukuma Plateau indicate a period of plutonic activity in that area approximately 110m.y. ago. Zircons from two granodiorites of the Shidara area have anomalously high 207Pb/206Pb ratios

This paper reviews briefly what is presently known about the lithologies, distribution, and ages of basement rocks surrounding the Gulf of Mexico and Caribbean Sea. The term basement is interpreted to mean pre-Mesozoic rocks, that is, rocks whose tim

Concordia resolution of uranium-lead analyses of zircons from rocks of the Guatemalan Cordillera indicates a period of plutonism, and perhaps metamorphism, in late Paleozoic times (345 +/- 20 million years). Gneisses of the Chuacus Series yield an ag

The decay constant of U^(235) has been evaluated from the radiogenic Pb^(207)/Pb^(206) ratios of several cogenetic fractions of zircon and uranothorite, analyzed by conventional mass spectrometric methods. Variation of the Pb^(206)/U^(238) apparent a

The Wolf River Batholith is a large anorogenic plutonic complex in central and northeastern Wisconsin that is similar lithologically to the rapakivi massifs of Finland. Quartz monzonite, the most abundant rock type present, can be subdivided into thr
