So I have a question about some garnet mapping that we attempted this week. There seems to be some artifacts of the scan lines, particularly in the trace elements. The major elements don't really show it. For example, here are Na and Mn vs. V and Sc.
For data reduction, I used the 3D trace element DRS and did a sum oxide. The same artifacts appear if I use an internal standard or do a semi quantitative DRS. These also have an extrapolation and Gauss 2D filter. As far as I'm aware, nothing went wrong in the ablation stage that might cause this. Is there any way to work these out? We're trying to look for zoning, like the Mn, and inclusions but these lines are making it impossible to see.
