Geotechnical Properties

Some physical properties of geologic materials are important in geotechnical engineering, but are not useful for geophysical interpretation. These properties are the dry strength, dilatancy plasticity, and toughness of the material. All four properties may be easily quantitatively categorized in … Continue reading

Detecting Physical Properties (Fieldwork)

Geophysical field surveys are used to investigate the subsurface. Geophysics may utilize passive techniques, measuring and mapping changes in the ambient field, or as active techniques that measures how the geological environment responds to an input signal. In either instance, … Continue reading

Characterizing Physical Properties (Labwork)

Measurements are made to determine the physical characteristics of geological materials. This is done by placing a homogeneous sample in specialized equipment designed to measure that particular property under either controlled or in-situ conditions. Extracting an intact sample is essential … Continue reading

How Physical Properties relate to Geological Materials

The physical properties of geological materials are what link geophysical data gathered at the surface to interpretation of subsurface geology. These properties are determined by the microscopic and macroscopic characteristics of the materials and their environments. Measurements of physical characteristics … Continue reading

Peer Review

The first time I was asked to peer-review an article, I was intimidated. How could I possibly cover all aspects of confirming if research was sound and ready to enter the academic literature? To start, as with many situations, I … Continue reading

Physical Properties of Geologic Materials

As Sedimentation Saturday was a lovely way of teaching myself more sedimentation and stratigraphy than I had previously known, for 2014, I’m taking the same route to look at the most fundamental concept in geophysics: the physical properties of geological … Continue reading
