Mkfarnam … yes … maybe not exactly "new" mountains, but it is well known that geologically there are “old folded” and “young folded” mountains.
For example in USA Appalachian are “old folded” mountains – appearing when America and Europe were touching each other. The same is with Ural in Russia – when Europe and Asia were touching.
80 000 000 years ago, when North America has begun shifting slowly to west, Cordilleran has begun to fold and rice up – it is an “Yang mountain” – it continues to go higher and higher. The same are cases with Alps in Europe, Himalayas in Asia, Andy in South America.
The case with the “Old mountain" in Bg is the same, but a little different. Geologically it is an “young folded” mountain, never mind we call it “Old” - people named it having no any relation with the geology …. Geologically the river crossing it (Iskar river - the photo below) is older than this mountain and it cut the mountain faster than rising up of the mountain, shaping very nice gorge I love to bicycle it so much …. Unfortunately I am not so sure, if my geology English is perfect … I hope you will understand …
