We have Concretion in shale around here . We called them turtle rocks as kids, In some areas their made of iron sulfide when they are either cut or hammered, they produce sparks and a burning sulfur smell




That seems to be consistent with these rocks...probably the same thing. Thank you.

Now, for something else. I've been looking at this geologic feature for a while. Its location is labeled in the top right of the map and you can see that it is very close to the area in question. In Google Earth, you can find it at: 31.3544972, 35.6010472. I can't find any indication that this is a volcanic vent or caldera. Also, just south of it along the ridge, there may be another structure or two but they're only about 50 feet wide. I don't see any other similar structures in the immediate area. Of course, if anything fell into one of those wadis, I imagine it would have washed away by now. From the images below, do you think it's worth somebody going up there to check it out? The 3-D feature of Google Earth doesn't seem to be terribly useful with features this small...I compared with other similar craters and they all seem to look like a flat image when you get to ground level even if there is a depression there.

[Map Correction: Numeira is actually a bit farther north...on that promontory jutting out into the right side of the southern basin.]
