2011-6-1 · The rock formation at Mt. Mufu consists mainly of dolomite, which has the longest history among all the rocks in Nanjing. The dolomite is classified as a marine sedimentary rock and can be found in massive beds. The formation period of all those rocks ranges from Cambrian periods, approximately 600 million years ago.
