Dingwuling Fm

Period: 
Neoproterozoic

Age Interval: 
Late Nanhuan (late Cryogenian), Nh (67, 68）


Province: 
Fujian

Type Locality and Naming

Southwest Fujian near Jiangxi. The Dingwuling Fm was named by the Compiling Group for Regional Stratigraphic Scale of Fujian in 1979. The typical section is located in Dingwuling village 14 km southwest of Changting County, Fujian Province.

Synonym: （丁屋岭组）


Lithology and Thickness

The Dingwuling Fm is mainly composed of grayish green metamorphic fine sandstone and siltstone intercalated with phyllite and chert. The basal 3-15 m is composed of yellowish green conglomerate and pebbly sandstone. The lower part is usually intercalated with dark purple and yellowish white metamorphic sandy mudstone and arkosic sandstone, and the lower and middle parts occasionally contain phosphatic bandings. The total thickness is 1531 m.


Lithology Pattern: 
Fine-grained sandstone


Relationships and Distribution

Lower contact

The base disconformably overlies the underlying Louziba Gr

Upper contact

It conformably underlies the Nanyan Fm

Regional extent

From southwest Fujian near Jiangxi to Northwest Fujian.
