Deep imaging techniques to understand subsurface structures up to 36 km below the crust
Update with Metal Earth Research Associate Saeid Cheraghi.
|
|
|
A large seismic survey was conducted as part of the Metal Earth project in order to image subsurface structures up to depths of 36 km. Metal Earth researchers are integrating the results of the seismic survey with the results from other geophysical, geochemical, and geological studies to improve our knowledge of the crustal architecture.
“Researchers can not make direct observations of the deep crust but seismic surveys will provide some inferences to aid in the interpretation of the crustal architecture. Seismic methods are similar to an x-ray image which will provide geologists with details to develop our understanding of the crust."

Reflection seismic shakes the ground causing waves to travel up to 36 km deep
Generally speaking, seismic shots will be generated by releasing energy with explosive materials (dynamites) or mechanical device (shaking the ground). This will generate seismic waves that travel into the ground, where they reflect off geological features which cause the waves to be reflected back to the surface.
Sensors placed on the surface receive the reflected waves. The reflected waves recorded by all of the sensors for a single seismic shot is called a shot gather. All the acquired shot gathers during the course of a survey are then processed using elaborate and sophisticated seismic processing algorithms to generate a subsurface reflectivity map.
|
|
|
|
“Some areas below the crust are transparent and do not reflect the signals, they mostly scatter seismic waves. Other areas act like a mirror and reflect the signal back to the sensors. Modeling the reflection and diffraction of seismic waves provide powerful insights into the subsurface geology."
|
|
|
“Imagine a sponge with metal balls inside. The seismic image of the sponge will be scattered waves and only the isolated metal ball generates a reflection".

In Memory of John Paul Golightly
It is with great sadness that we advise you of the passing of John Paul Golightly in Sudbury on Sunday, October 14 at the age of 78 years.
Paul was one of the more active geologists in Sudbury, attending most Sudbury Geological Discussion Group meetings and Laurentian University seminars, and one of the most active Adjunct Professors at LU, teaching in the Magmatic Ore Deposits modular course, serving on numerous thesis advisory and examination committees, and working regularly with other members of the Mineral Exploration Research Centre at the Harquail School of Earth Sciences on magmatic Ni-Cu-PGE deposits.

April 6-15, 2019
Modular Course on Exploration for Hydrothermal Ore Deposits: Genesis & Exploration.
|
|
This 10-day course focuses on the geology, alteration, and origin of hydrothermal ore deposits. Deposit types include epithermal and mesothermal precious metal, porphyry Cu-Mo-Au, IOCG, sediment- and volcanic hosted base-metal deposits, and U and REE deposits. Emphasis is placed on the processes responsible for their formation, the recognition of alteration halos, and features pertinent to exploration.
