Archaeal Communities in Deep Terrestrial Subsurface Underneath the Deccan Traps, India

Archaeal community structure and potential functions within the deep, aphotic, oligotrophic, hot, igneous province of ~65 Myr old basalt and its Archean granitic basement was explored through archaeal 16S rRNA gene amplicon sequencing from extracted environmental DNA of rocks. Rock core samples from three distinct horizons, basaltic (BS), transition (weathered granites) (TZ) and granitic (GR) showed limited organic carbon (4–48 mg/kg) and varied concentrations (
