Carbonaceous Alteration
Carbonaceous Alteration
Thor is a sediment-dominated geological environment. Within these sedimentary rocks, a large volume of hydrothermal activity has occurred that led to the development of the epithermal deposit. Taranis has been able to document that the carbonaceous material occurs in the sediments around the epithermal deposit. Ground geophysics (VLF) is a very useful tool for the mapping of this carbonaceous material. Airborne geophysics has shown a very distinct and large horsehoe-shaped conductive feature that is associated with an area directly below the Thor epithermal deposit, and this is believed to be related to a large intrusive body concealed below the surface that has produced a concentric conductive anomaly around an intrusive body. This is a form of contact metamorphism commonly found around intrusive bodies hosted within sedimentary rocks that contain organic material. |
