Porphyry and skarn-type molybdenum-(tungsten) and skarn-type lead-zinc deposit. Nannihu is the second largest molybdenum deposit in China and has been mined since the 1970s. In the early 21st century, rich skarn-type lead-zinc ore bodies were discovered in the periphery of the molybdenum ore bodies.

Mineral List

34 valid minerals.


Mineralization age: Jurassic : 156 ± 8 Ma to 146 ± 5 Ma

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
