Horizontal movement in the Earth's crust
Journal of Geophysical Research, 1960The conventional method for determining horizontal movement in the earth's crust has been to reobserve networks of triangulation and compare the coordinates of the adjusted results. A new method of analysis of reobservations is presented. The changes in the angles in a network indicate the presence of strain or deformation within the crust.

The Abundance of Thallium in the Earth's Crust
Science, 1947lipids, the acetone fraction had a marked inactivating action as well as a low surface tension; the ether and hot alcohol-ether fractions were only moderately active, irrespective of surface tension. The inactivation of neurotropic viruses by serum lipids is now being investigated in connection with (a) the mechanism, including influence of the degree ...

Earthquakes are localised movements of Earth’s surface rocks. They cause vibrations that may do great damage to buildings, cause landslides, and result in great loss of life. When an earthquake occurs, vibrations pass through the whole planet and also pass round the circumference in the surface rocks (the crust, see Figure 25.1).

Deformation of the earth's crust
Geological Society of America Bulletin, 1939INTRODUCTION If the deformation of the earth’s crust, to which the face of the earth owes its salient features, had been one dynamic event, a careful analysis of the pattern produced would yield sufficient clues to lead directly by inductive reasoning to an understanding of the forces that produced it.

In the previous chapter we looked at how the isotopic compositions of various elements, particularly radiogenic elements, are effective in throwing light on the history of the earth, acting as “fossils” that record the evolutionary process of the earth.
