I carefully checked the your interesting work and think that after the comments of the reviewers, who suggested only minor modifications, the manuscript is now suited for publication in SE. However, before I can recommend publication, I have also three important points, which have not been raised by the reviewers, but which I think are really important but can also be easily implemented by the authors:
1) Both maps a) and b) in Figure 1 need coordinates.
2) The map in Figure 1B is difficult to read, because the colors in the map are very different to the colors in the legend. The reason for this is, that the authors drape in the map transparent colors over a hill shade relief but use non-transparent colors in the legend. I suggest to cut out a rectangle of the hill shade and also display it below transparent colors in the legend.
3) The documentation of the important sample location is really poor. Figure 2 caption must give GPS coordinates of sample locations R1, R2 and R3 and Figure 2 B and C need orientations indicated.

Best regards Bernhard Grasemann
