Palo Duro Canyon State Park, Texas, USA: eroded cliff side - Geologic time periods marked by major changes in the fossil record - rock strata covering the Permian age, Triassic age, Miocene-Pliocene age and at the top the Quaternary age - this cliff includes the Permian-Triassic (P-T) extinction boundary, colloquially known as the Great Dying, that took place about 248 million years ago. The extinction was caused by climate change. The main cause of extinction was the vast amount of carbon dioxide emitted by volcanic eruptions that created the Siberian Traps, which elevated global temperatures and acidified the oceans.

Agate is a microcrystalline variety of quartz, chiefly chalcedony, cryptocrystalline form of silica.  Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks but can be common in certain metamorphic rocks. Most agates occur as nodules in volcanic rocks or ancient lavas where they represent cavities originally produced by the disengagement of volatiles in the molten mass which were then filled, wholly  by siliceous matter deposited in regular layers upon the walls.
