What the Bricks Tell Us from a Temple at Burkhan Khaldun Mountains: Chronological Insights from pIRIR Luminescence

A groundbreaking study leverages post-IR infrared luminescence (pIRIR) to date bricks from the Buddhist temple ruins at Burkhan Khaldun Mountains, Mongolia, revealing their manufacturing period between 1230±50 AD and 1280±40 AD. This aligns with the era of extensive construction in Karakorum, offering chronological insights into the region's architectural history. The research applied both coarse and polymineral fine grain techniques to feldspar, distinguishing it from previous methods. Additionally, the study compared mineralogical compositions of bricks from various temple sites, including those in Karakorum and Erdene Zuu, enhancing our understanding of historical brick production and trade.
