Abandoned village of Tanuf – bombed during the Jebel Akhdar war of 1952 – 59.
A rock art file that I thought I had lost, have the B&W version here on my blog; also a B&W negative. I knew I had a colour version somewhere and here it is. 🙂 Also its location was not marked on my map, fortunately there was a map reference with the file.
There is a lot going on in this image, at least three different periods, the very early ones being very faint. The disc has been redone twice and as a pair each time, makes me think it could be a tribal sign like Wusum (used by Bedouin for camel identification) and not as thought previously, that it represented the sun.
There are two or even three very faint anthropomorphic images, along with one horse with rider and above it possibly a camel with rider.
This sort of choke point is quite common in most of the major wadis in Oman. Finding a way around or over can be a challenge, especially in the summer months when the rock is warm (hot) and covered in fine dust.
Accumulation of rock like this one is the result of the many Cyclones Oman has endured over the centuries; well trodden paths and even Falaj get blocked. There are several instances were a whole village has moved because of the loss of water when a Falaj gets blocked or damaged beyond repair.
The Al Hajar stretch for about 700 km across the north of the country and rise to over 3,000m (Jebel Shams – mountain of sun) from the coastal plain. Sediments at the core were mainly laid down during the Late Permian to Late Cretaceous in the Tethys ocean basin that had resulted from the break-up of Gondwana.
The Arabian Plate collided with and pushed against the Iranian Plate, resulting in mountains chiefly made of Cretaceous limestones and ophiolites.
Rock outcrops in the Al Hajar Mountains, the Huqf and Dhofar span about 825 million years and includes at least three periods when the country was covered by ice.
Oman, located at the south-east corner of the Arabian plate, is being pushed slowly northward, as the Red Sea grows wider. The Al Hajar Mountains and valleys of Musandam are dramatic reminders of this: Oman is fairly quiescent tectonically but the Musandan experiences occasional tremors as the Arabian Plate collides with the Eurasian Plate (I remember coming back from holiday & finding bathroom tiles all over the floor from one of these tremors).
During the Cretaceous Period Oman was located adjacent to a subduction zone and a portion of the upper mantle along with overlying seafloor volcanic rocks were thrust over the continental crust. This obducted sequence of ultramafic to mafic rocks is the Semail Ophiolite complex. The ophiolite is locally rich in copper and chromite ore.
The interior plains of Oman are of young sedimentary rocks, wadi gravels, dune sands and salt flats. Beneath them is a several kilometre thick stack of older sedimentary rocks that host the country’s hydrocarbon resources.
