Structural controls on commodity deposits

  • Build your targeting model through a tectonics to structural to deposit scale sequence; As Nature did.

  • Optimize your data acquisition programs to fill structural knowledge gaps; Structure controls mineralization!

  • Extend your trapping and deposition model along underexplored, prospective, structural trends.

Results-based integration for your structural challenges at tectonic, structural, permeability and mineralized vein scales.

Experienced in a range of geodynamic settings, tectonic stress regimes, deformation styles and implications for mineralizing fluids.

Compressional deformation:

- Zagros, Canadian Rockies, Scottish Highlands, Apennines, Turkey and Cyprus, and Caucasus fold-thrust belts.

Extensional deformation:

- Upper Rhine Graben, Oman, N. Atlantic, North Sea, Wessex Basin, NE India and Mid-Atlantic Ridge rift systems.

Shear deformation

- Mid-Atlantic Ridge, Troodos ophiolite, N. Anatolian and Zagros transform faults, transfer zones and tectonic indentor systems.

Fracture system and vein analyses (satellite imagery, outcrop, image log, wireline logs, drill core):

- Vein-hosted gold mineralization in Tanzania and Greenland.

- Granulation seams in clastic petroleum reservoirs, onshore U.K.

- Fractured carbonate petroleum reservoirs in Iraq, Canada, Italy.

- Fractured basement petroleum reservoirs in Yemen and offshore U.K.

Salt deformation:
