The field trip starts from Beijing City, via the Ming Tombs Reservoir, Deshengkou, the Guanting graben, Longqing Gorge, Yanqing UNESCO Global Geopark, Silicified Woods, Dinosaur Footprints, Wulong Canyon, Badaling Great Wall and ends in Beijing City. The trip route (Stops 1-8) on October 27 (the first day) extends in NW direction, crosses the Archean metamorphic complex and the famous Middle-Late Proterozoic classic section, and passes through the Mesozoic structural-magmatic belt and the Cenozoic basin-and-range system. The major trip route (Stops 10-14) on October 28 (the second day) extends in an EW direction along the Baihe River. Visitors will see the Archean metamorphic rocks of the cratonic basement, Middle-Late Proterozoic stratigraphic systems, Jurassic-Cretaceous granitic complex, Late Jurassic volcanic rocks, Late Jurassic Silicified Woods and Dinosaur Footprints, the Luliangian Movement boundary, Yanshanian thrust, and Himalayan rift and landscape. Visitors will also have a stop at the Ming Tombs Paleomagnetic Station for the seismic reflection profile and drill core across the largest nappe in the northern Tibetan Plateau.
