A tale of two prehistoric oceans and the chosen rock
Description
This episode is dedicated to Letty's friends at Fort Nelson and an ex-colleague who was the first Finnish person she met.
In scene 8, Aaranya informs Prof. Scamander that she will leave the Quiet Lake study area only after she finds an eclogite site. She found three.
She is reading the abstract and some snippets from a few research papers based on the eclogites found in the Canadian Cordillera (Rose Mountain, Last Peak, and St. Cyr Klippe).
About midway through the episode, you will learn how these Yukon eclogites are connected to a prehistoric ocean and the resurrection stone (one of the deathly hallows). Another ocean is briefly mentioned and will be covered in a future episode in the hope that Aaranya gets better at French.
Aaranya is referring to the following resources:
- An occurrence of eclogite near Tintina Trench, Yukon (Tempelman-Kluit, 1970)
- Eclogite from Central Yukon: A record of subduction at the western margin of ancient North America (Erdmer and Helmstaedt, 1983)
- The exotic nature of the Last Peak eclogite in the Teslin zone, south-central Yukon Territory (de Keijzer and Williams, 1999)
- Geologic setting of eclogite-facies assemblages in the St. Cyr Klippe, Yukon - Tanana Terrane, Yukon, Canada (Petrie, Gilotti, McCelland, van Staal, and Isard, 2015)
- Northern Cordilleran terranes and their interactions through time (Colpron, Nelson, and Murphy, 2007)
- The Slide Mountain ophiolite, Big Salmon Range, south-central Yukon: Preliminary results from fieldwork (Parsons, Ryan, Coleman, and van Staal, 2016)
- Late Permian cold subduction in the Yukon-Tanana Terrane, Yukon Territory, Canada: Progressive elcogitization in the lawsonite stability field recorded by lawsonite and garnet inclusions in garnet (Rowe and Faber, 2019)
- First para of section 23.4 on page 608 from the book Notions de géologie (4 ed.) by Bruno Landry
Note: This is a work of fiction, so everything herein is imaginary with some dangling facts. Also, this is a MeriMetso episode (a Frazden house that loves the unfathomable), but you will NOT hear a few seconds of the house song (Isä) by Vesterinen Yhtyeineen because Aaranya revealed Paracelsus' gemstone switch in this episode.
