Hi, I have an issue with making a constraint grid for 3D gravity inversions. I have made a blank grid with all values 1 in Oasis, then edited an area of it to be 0 in Arc. I then want to re-import it into Oasis to use, but opening it appears to do some sort of smoothing/interpolation between cells in an attempt to increase…
I converted 4 layer, at various depth, using GMSys-3D. layers at depths of -250, -500, -750, -1000 m depth. before converting, I used magmap to calculate the apparent magnetic susceptibility for each layer to be used as lateral distribution. I converted the output from magmap filter to be in MicroCGS for GMSys3D. results…
Good morning all, I am currently running simplified 3D wedge models approximating my geological scenario with the ultimate goal to assess resulting depthing uncertainties through structural Inversion considering the inherent input density and picking uncertainties. After running some initial tests, I discovered some…
I have inverted three layers at various depths (e.g. at 250, 500, and 750 meter). the results are three relief, isopach, or susceptibility layers. is it possible to create voxi from those layers?
I have an aeromagnetci data which was flown at 300 m height. The DEM data ranges from 373 to 2515 m. when I trying to use this data in GMSys 3D, I have to input the survey elevation at constant level above 2515, which is not real. I guess there is something missed, if some one help, will be highly appreciated.
Dear community, I am a newbie in setting up 3D models for gravity inversion and forward modelling and need your advice on how to structurally inverted for the top of salt surface w/o using VALEM? (1) The input surfaces I use for structural Inversion are very conceptual as I do not have seismic data to further constrain…
