#Sanidine from the Fish Canyon Tuff is essential to understanding the pace of events in the #Cenozoic

High potassium, quickly erupted and cooled, and old enough to have accumulated sufficient 40Ar from radioactive decay. These crystals calibrate neutron flux for 40Ar/39Ar dating. The 28.2 Ma age of the FCT sanidine has been fine-tuned using #Milankovitch cycles of other ash beds in stable sedimentary basins.

"With your arms spread wide again to represent all time on earth, look at one hand with its line of life. The Cambrian begins in the wrist, and the Permian Extinction is at the outer end of the palm. All of the Cenozoic is in a fingerprint, and in a single stroke with a medium-grained nail file you could eradicate human history."

-- John McPhee, _Basin and Range_, pg 126

Introducing Deep Time Detectives! 🔎

Deep Time Detectives is an educational resource developed by CABAH on Australia's deep history, featuring a series of animated videos.

I drew a collection of original illustrations and animated elements for these videos

Happy #NationalScienceWeek !

what but imagination could have read
granite boulders back to their molten roots?
And how far back was back, and how far on
would basalt still be basalt, iron iron?

—Edwin Morgan certainly though so, and was inspired – by Burns & Hutton – to write “Theory of the Earth” (first published in New Writing Scotland 2, 1984)

Till a’ the seas gang dry, my dear,
And the rocks melt wi’ the sun…

James Hutton met Robert Burns in 1787. Later that year, Burns chose to visit some of the sites discussed in Hutton’s THEORY OF THE EARTH. Is there an echo of Hutton’s “deep time”—oceans evaporating, rocks melting—to be heard in Burns’s “A Red, Red Rose” (pub. 1794)?

James Hutton (1726–1797), father of modern geology, was born #OTD, 14 June (NS; 3 June OS). One of the first European proponents of “deep time”, the conclusion of his 1788 paper “Theory of the Earth” has been called one of the most lyrical sentences in all of science:

The result, therefore, of our present enquiry is, that we find no vestige of a beginning,—no prospect of an end.

🧵 #OTD the #Titanic sank in 1912. When I was a very small child, I knew an old woman who narrowly escaped this disaster. As the governess of a US millionaire's children, she was supposed to be travelling on the Titanic. They arrived too late in England and couldn't get tickets.

Shortly before her death, she gave me some old #yarn. I haven't dared to use it to this day because it's like travelling back in #deepTime. 113 years can feel so near.
