{ "currentVersion": 10.71, "serviceDescription": "This dataset represents the Tz component of the gravity tensor derived from the Bell BMC2010 FTG/AGG survey, gridded at 25 m resolution in NAD83 NB Stereographic projection.The dataset contains the Tz tensor component extracted from the reconstructed gravity tensor of the Bell BMC2010 FTG/AGG survey. Tz represents the first vertical derivative of the gravity field and is highly sensitive to vertical density contrasts, making it particularly useful for detecting shallow intrusive bodies, faults, lithological contacts, and other subsurface structures with significant vertical variation. The dataset is provided as a 25 m grid in NAD83 New Brunswick Stereographic projection and supports detailed structural interpretation and mineral exploration.This raster was created by processing the original FTG profile data using a density of 2.8 g/cc, reconstructing the full gravity tensor from the measured components, gridding the tensor using a tensor-interpolation algorithm at 25 m resolution, and extracting the Tz component from the final tensor grid. It is delivered as an ER Mapper (.ers) raster.Data created Sept 2025.", "name": "Geophysics_Gravity_Gradiometry_Individual_Surveys/Bell_BMC_Tz", "description": "This dataset represents the Tz component of the gravity tensor derived from the Bell BMC2010 FTG/AGG survey, gridded at 25 m resolution in NAD83 NB Stereographic projection.The dataset contains the Tz tensor component extracted from the reconstructed gravity tensor of the Bell BMC2010 FTG/AGG survey.
