Bell Geospace is a leading surveyor and purveyor of high quality airborne Full Tensor Gradiometry (FTG) data for mineral exploration. The company has acquired and processed in excess of two million line kilometers worldwide and has delivered over 150 fully interpreted projects. FTG data is effective both in regional exploration areas as well as in focusing and expanding exploration efforts in areas of known mineral deposits.
For an overview and some sample case studies, please check out this 20 minute presentation recorded for ORE GEOLOGY conference, 2021.
Gravity and density help identify rocks and materials due to contrasts in the geology which are measurable with a gravity gradiometer. The technology measures the rate of change of gravitational acceleration due to underlying rock properties.
For an interesting overview of why density matters, check out the Minerals and Gravity Gradiometry podcast.
We own three Basler BT-67 aircraft and each aircraft has built-in gravity gradiometry technology alongside scalar gravity and magnetics. The aircraft are adapted for low noise and low impact.
Full Tensor Gradiometry is superior airborne data. Bell's highly accurate and unique methods deliver an accurate perspective on the earth's internal density contrasts and provides a rich perspective on fine structure and short wavelength characteristics of the field.
