Geological & Geophysical Consulting Services
As a practicing geologist and geophysicist, I offer a
range of consulting services to individuals and businesses.
Two examples of the types of services that I provide are given below.
For questions regarding consulting services, please contact me at
Geological Review and Summary
Every place on the Earth has a unique geologic story that
stretches back millions to billions of years. Even the most seemingly mundane
settings hold rich histories of times when the Earth looked drastically different.
While peering back millions to billions of years can be a mind-bending experience
due to the unfathomable magnitude of the time scales involved, the view nevertheless
sparks the imagination of the incredible ways in which our planet has evolved over millennia.
As a student of North American geology, I've learned much about the geologic history of the
continental United States, both through my research and through my travels.
There are many situations in business in which it is valuable to have
some kind of understanding of the geologic history and setting of some location.
One of the main services that I provide is crafting geologic overviews, reviews,
and summaries of a given region of interest. The resulting product can be as simple
as a general regional geologic overview, or it can involve detailed geologic map compilation
and a deep search through regional or local geologic literature.
Such geological reviews or summaries are particularly useful in ecotourism and other
location-based industries that rely on their natural setting.
For example, I have worked with the owners of the Changing Sky Retreat
to provide a regional geologic overview of their property. My services added value to
their operation by elucidating the natural history of their surroundings to their visitors.
Electromagnetic Geophysics for Subsurface Investigations
I work closely with ModEM Geophysics
(and by extension Consulting GEO)
to provide a range of services for exploration and R&D applications. Such services include data processing, data quality control,
inversion, resolution analysis, interpretation, and geophysical/geological synthesis.

If a volcano erupts in the Archean and leaves no geologic record, did it really happen?
