The Deccan Traps, a basalt cover in India that now covers 50,000 square kilometers, was formed by volcanism 66 million years ago. It is assumed that the original area of lava covered up to 1.5 million square kilometers and that this volcanism was partly or even entirely responsible for the extinction of the dinosaurs at the Cretaceous-Tertiary boundary. Some of the huge gas cavities enclosed in this lava have filled up over millions of years with fantastic crystal formations of zeolitic minerals. The steps are usually recovered during quarrying work, but also during well construction work, for example, where huge crystal caverns were documented to have been cut into in the 2010s to 2013s.
