Service Description: This dataset represents the Tyz 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 Tyz tensor component extracted from the reconstructed gravity tensor of the SWN_NBStereo survey. Tyz represents the mixed second derivative of the gravity field in the Y–Z directions, highlighting vertical and lateral density contrasts. This component is useful for mapping faults, lithological contacts, intrusive bodies, and other steeply dipping geological structures, 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 Tyz component. The final grid was exported in ER Mapper (.ers) format.Data created Sept 2025.
