The main bulk of the Buda Hills, which is predominantly limestone and dolomite, can be dated back to the Triassic. The Triassic period is the first large unit of the geological Middle Age that started more than 251 million years ago and lasted for over 50 million years. The Atlantic did not exist and neither did the Carpathian Basin. The rocks of the Buda Hills were formed in a tropical climate, in shallow and deeper regions of the ocean during the Triassic.
Limestone and dolomite forms the most characteristic cliffs of the Buda Hills. Water and ice that slowly but unstoppably eroded the surface, played important roles in shapping these formations on the hilltops and forest-covered hillsides. Other characteristic formations, like the steep cliff surface overhanging the Danube arose when whole masses shifted position. Very often, these shifts were accompanied by the eruption of hot springs that brought silica acid with them from the depths of the bedrock. Rocks soaked in silica acids became much harder and more resistant. Over time, the surrounding rock wore off gradually, leaving the sturdy part jutting out like a sore thumb.
The bestknown rocks of the Buda Hills are those that are easily accessible and hikers come across them frequently.
