Interesting Geology found at Huqf; all these were within a couple of metres of each other. This is where I wish my knowledge of the subject  was more than non-existent……….

Very frustrating !

The yellow/orange had a very sulphurous smell and the dark red/brown was powdery and stained the fingers.

This one and the above seemed to be Iron ore ?

Unusual (For me anyway) crystal formations that were very heavy for their size.
