Would anyone care to comment on this stunning rock.  It is a few miles inland from the Costa Blanca.

Hi Jane
This the famous Las Medulas Roman Gold Mines in León, the peaks are formed by the collapsed mineshafts.
This red rock is quite common around here
Regards
Dave

Just shows that Spain can rival any rock formations on the other side of the pond  :) I'm sure Nick will stumble on this at some point Jane and give an expert opinion on the rock type. I guess sandstone but as to the type  :noidea:
Both great images!!

We were exploring an old road to get to the coast from Castalla, which is 30 miles inland from Alicante, without using the autovia.  This photo was taken near the end in the hills behind San Vicente del Raspeig.  We have seen other areas of this deep red earth in the area but this particular formation, with the white streaks, was worthy of a long look and a few photos.  The road was about 1.5 cars width and took about about an hour to travel around 20 miles.  We only met 2 other cars.

As Lisa says it could be a sandstone ....... though it is very probably a marine sediment and could be a reworked sandstone ie it was once on land and eroded and then deposited out at sea and then uplifted again. It could also be a limestone of some sort with iron staining??? Or perhaps a sandstone that has be cemented together with dissolved calcium carbonate at some time in its formation.

The white I think could be 'recent' leaching of salt, gypsum or even perhaps calcite by water ..... if you look carefully it loks like leaching and not something that was formed along with the rock ..... its not in bands .....................

My geology is rusty and this is a best guess and could be very wrong. Though the area you were in is I understand is generally all old marine sediments (now sedimentary rock) with evapourite deposits (evpourated salt etc deposits ) that have been uplifted. Some are fairly old and some fairly young.........

Thank you for your comments Steve.  We guessed that maybe there was iron in there causing the deep rusty red but my geology knowledge is very limited.  Whatever it is it's an impressive sight.  I will be on the look out for more formations in the area when we are next in that direction
