Drilling induced pyrometamorphism of clastic sediments in the Lavø-1 well, Denmark

Key Points

• Pyrometamorphism significantly alters clastic sediments due to drilling impacts, enhancing mineral transformations.
• High geothermal gradients of up to 200 degrees Celsius were observed near the Lavø-1 well site.
• Observational analysis of sediment samples obtained during drilling identifies key metamorphic processes.
• Findings highlight the need for improved practices in sediment management during drilling operations.
