What you said regarding time this puts things in perspective to me... I never think about anything in america continent as 'ancient', lmao. Must remember this land has been there since forever... I know the feeling about timelessness is because you can see the layers and time periods lol very interesting. I'm proud of your love for geology, its an amazing field
Thank you dear! All the Earth is so ancient but we tend to think in terms of the countries we have now but yeah America, esp that part is especially old. I adore it so much!
Geologists have found precambrian volcanic and metamorphic rocks over 1.5 billion years old in New Mexico. These rocks form the core of the mountain ranges east of the Rio Grande, with the oldest stone found in the Brazos, Taos and Nacimiento.
New Mexico was covered by the Permian Sea during the Paleozoic era , a vast, shallow body of water that created beds of limestone, sandstone, gypsum and shale. The sea dissipated at the end of the Paleozoic era and a great barrier reef formed in southern New Mexico. As the water evaporated, large deposits of salt, potash and gypsum remained.In the Mesozoic era, the sea continued to recede, with dinosaurs roaming the region...Eventually North America broke away from what remained of the Pangaea land mass and drifted west, colliding with the Farallon plate.
