FTG Case Studies
Bell Geospace's FTG technology can be used in a wide variety of scenarios. The following list shows some examples of the areas in which FTG technology can help. Please note: this list is not definitive and is provided for illustration purposes only - please contact Bell Geospace to discuss your exploration requirements.
Minerals

Placer Diamonds
- Deposit Description: Placer concentrations of diamonds occur mainly in large, high-order stream channels and at the base of paleo-channel sequences.
- Features likely to be detected: Streams and Paleochannels
- Case Study
Diamonds
- Deposit Description: Diamond deposits hosted in kimberlites. Kimberlites are small carrot-shaped diatreme which occur mainly in stable tectonic settings (e.g. within shield and stable cratons).
- Features likely to be detected: Kimberlite pipes and craters
- Case Study
Disseminated Gold
- Deposit Description: These deposits occur in highly varied lithologies, usually greenschist metamorphic grade, ranging from virtually undeformed to totally schistose. Granite-greenstone belts-mafic ultramafic and felsic volcanics are common host rocks.
- Features likely to be detected: Shear and alteration zones, lithological contacts, skarns
- Case Study
Gold (geothermal type)
- Deposit Description: Gold and silver in quartz veins, stockworks and breccias form in high- level to near-surface environments. The ore commonly exhibits open-space filling textures and is associated with volcanic-related hydrothermal to geothermal systems.
- Features likely to be detected: Alteration zones, skarns
Iron Oxide Copper Gold
- Deposit Description: The iron-oxide copper gold or IOCG deposit class include a range of mineralization styles. They are dominantly magnetite-and/or hematite-rich deposits. These deposits are characterized by i. major regional thermal event, ii. Fe-rich host supracrustal sequences and iii. major crustal features such as rifting.
- Features likely to be detected: Hematite ore, lithological contacts, faults
- Case Study
VMS-Type
- Deposit Description: These deposits occur as thin sheets of massive to well layered sulfides within interlayered, terrigenous clastic rocks and calcalkaline basaltic to andesitic tuffs. They can reach up to a few meters thick and up to kilometers in strike length and down dip.
- Features likely to be detected: Inclined sheet of massive sulfide, alteration zones, basin edges
- Case Study
Nickel / PGE's
- Deposit Description: These deposits are hosted in the basal portion of the sequence of layered mafic and ultramafic intrusion.
- Features likely to be detected: Host layered mafic and ultramafics
Copper (porphyry)
- Deposit Description: These deposits occur as stockworks of quartz veins, closely spaced fractures and breccias containing sulfides occur in large zones in or adjoining porphyritic intrusions and related breccia bodies. The mineralization is spatially, temporally and genetically associated with hydrothermal alteration of the host rock intrusions and wallrocks.
- Features likely to be detected: Intrusion domes, hydrothermal alteration, breccia zone
Structural Mapping
- Deposit Description: Both regional and prospect level structural features may be mapped. Major crustal features are such as the rift systems, major strike slip faults e.g. the San Andreas Fault etc.
- Features likely to be detected: Regional and detailed, faults edges, lithological contacts
Barite
- Deposit Description: Sedimentary-hosted, stratiform or lens-shaped barite bodies, which may reach over ten meters in thickness and several kilometers in strike length.
- Features likely to be detected: Barite ore
Uranium
- Deposit Description: Uranium minerals occur as fracture and breccia fillings and disseminations in elongate, prismatic-shaped or tabular zones hosted by sedimentary/metasedimentary rocks located below, above or across a major continental unconformity.
- Features likely to be detected: May detect breccia zone and alteration zone, shallow ore
Oil and Gas

Gas Hydrates
- Deposit Description: Gas hydrates are structurally controlled and tend to form along the rims of sedimentary basins and over salt ridges where ongoing salt deformation and active faults provide efficient conduits for fluid migration from the deep subsurface petroleum system into the shallow gas hydrate stability zone.
- Features likely to be detected: Low gravity zone associated with gas hydrate
- Case Study
Salt Domes
- Deposit Description: Salt domes are diapiric structures involving the upward flow of low-density salt. The circular nature of these features is an indication of the fact that salt domes form as a result of upward flow independent of tectonic activity. The flanks of these structures provide excellent trapping mechanisms for oil and gas.
- Features likely to be detected: Cap rock and salt dome
Pinnacle Reefs
- Deposit Description: These are carbonate formations that may grow to form a dome or anticline-like feature, can be important source of oil and gas.
- Features likely to be detected: Anticline / dome carbonate features
