- •
A granulite-facies overprint eclogite is identified in North Qinling Belt.
- •
Five metamorphic stages are recognized from this eclogite.
- •
A clockwise P–T–t path is obtained by combining pseudosection and geochronology.
- •
The eclogites record a single cycle of subduction and multiple stages of exhumation.
