Numerous potassium-argon ages have been determined on a variety of rocks from the Altiplano of Bolivia with the intent of providing data on the three following problems: (a) ages of the batholiths that intrude early Paleozoic sedimentary rocks along

From the results of this preliminary survey it would appear that the bathyliths of the southern belt of the Tasman Geosyncline represent a history of continuous tectonic activity from Middle Silurian through to Middle Devonian, with a gradual movemen

Summary It is shown that the Poincart-Brillouin approach to finite elastic strain theory leads to equations completely equivalent to those obtained by the Murnaghan-Birch approach. Applying the Brillouin pressurestrain equation to the Earth’s inter

Potassium-argon ages of sanidines, biotites, and basalts are found to be in essential agreement with time-sequential dating of Tertiary land mammals. A detailed time scale of the Tertiary based on an age breakdown is given.--H.C.W.S

Criteria for achieving an order of magnitude discrimination between underground explosions and shallow-focus continental earthquakes are presented. The basis of all these criteria is the gross difference between earthquakes and explosions as regards

A technique for the potassium-argon dating of high potassium feldspars of less than 50,000 years age is described. The technique is applied to the obtaining of high precision ages in the time-range 60,000-2,000,000 years. Sufficient data are presente

This paper constitutes a compilation of seismicity data available in the literature plus regional and worldwide data obtained from the USCGS Preliminary Determination of Epicenter (PDE) lists. Data are presented in the form of the recurrence relation
