This dataset represents the Tzz component of the gravity tensor derived from the SWN_NBStereo (Lantern) FTG/AGG survey, gridded at 25 m resolution in NAD83 NB Stereographic projection.The dataset contains the Tzz tensor component extracted from the reconstructed gravity tensor of the SWN_NBStereo survey. Tzz represents the second vertical derivative of the gravity field, which is highly sensitive to vertical density contrasts and shallow subsurface structures. This component is useful for detecting faults, intrusive bodies, lithological contacts, and other vertical density variations, supporting high-resolution structural interpretation and mineral exploration. The dataset is delivered as a 25 m grid in NAD83 New Brunswick Stereographic projection.This raster was produced by processing the SWN_NBStereo FTG/AGG profile data using a density of 2.8 g/cc, reconstructing the full gravity tensor from the measured components, interpolating the tensor to a 25 m grid using a tensor-interpolation algorithm, and extracting the Tzz component. The final grid was exported in ER Mapper (.ers) format.Data created Sept 2025. |
