Puling Fm

Period: 
Neoproterozoic

Age Interval: 
late-Late Qingbaikouan (late Tonian), Qb (60)


Province: 
Anhui,

Type Locality and Naming

Southernmost Anhui. The Puling Fm was named by Xia Bangdong et al. in 1962. The typical section is situated in Puling village west of Qimem County, Anhui Province. Upper formation in Likou Gr.

Synonym: （铺岭组）


Lithology and Thickness

The Puling Fm is composed of greenish gray phyllitic andesitic tuff interbedded with amygdaloidal meta-andesite, locally with copper-mineralization zones. The thickness is about 112 m.


Lithology Pattern: 
Volcanics


Relationships and Distribution

Lower contact

It rests unconformably on the underlying Dengjia Fm

Upper contact

The upper part underlies unconformably the overlying Xiuning or Xiaoanli formations.

Regional extent

Southernmost Anhui. In the juncture of Anhui and Zhejiang Province (Tunxi to Kaihua).

Strata corresponding to the Puling Formation were named as the Jingtan Formation by the Anhui Party of Regional Geological Survey, 1971, which are dominated by intermediate to acidic volcanic rock and tuff.
