///This study reports the discovery of lawsonite and was also discovered in accompanying eclogite. It occurs as enclaves in quartz grains. Using internally consistent mineral thermodynamic detabase of Holland and Powell （1998）, and Domino/Theriak calculation software by de Capitani and Brown （1987）, the authors calculated metamorphic pT conditions of the HP/LT metamorphic belt. The results show that the Qingshuigou high-degree blueschist experienced metamorphic transformation from lawsonite glueschist to epodite blueschist, and has the similar pT condition to that of lawsonite-bearing eclogite. Combined with the lithological, geochemical and isotopic data above, Early Paleozoic tectonic evolution process of North Qilian orogeny was further discussed.
