High-resolution (U-Pb) age dating of Deccan eruptions has remained elusive – until 2014 when the Princeton team discovered zircon crystals for dating of basalts in C29r yielding accuracy within +/-15-25 ky. Our ongoing work in collaboration with Blair Schoene, Kyle Samperton, Sam Bowring (MIT) and Thierry Adatte (U. Lausanne) has succeeded in dating 3200 m of Deccan basalt flows in C29r as having erupted over just 630,000 years.
