#tufa — Public Fediverse posts

Es gibt einen neuen Artikel auf #FiB_Bahn: Teil 1 zum Thema Zugkreuzungen. Dafür haben wir den Bf Grimmen besucht und außer der – hier wegen Reisendensicherung aufwendigen ð– Zugkreuzung – auch noch eine Besonderheit aufgegriffen: Die „Technische Überwachung Fahrweg“, kurz #TüFa.

Hier geht’s direkt zum Artikel: https://lichtenblo.notion.site/Wo-Z-ge-sich-kreuzen-Teil-1-Grimmen-1f40f6643fec80529c27e10b359e44db

Mono Lake Tufas

Description: It's odd to think this geologically interesting area of California used to be a research facility ran by the US Navy.

Now the area is a California State Natural Area, set aside to protect the unique tufas that like the South shore of

Very late entry! #StillFridaySomewhere

I think we can all agree that the perfect place to play a sensitive power ballad is on the shores of a highly alkaline volcanic lake in inland California, decorated by bizarre limestone pillars! #tufa

From the shores of Lake Mono comes...

These rocks that look a bit like limestone cave formations growing on a substrate of basalt (a rock not known for growing such things) are tufa (calcium carbonate) that were deposited with the help of algae, so said the sign at Picnic Cave, a short way down the ledge. It means cyanobacteria, blue-green algae. Tufa forms underwater. These were formed when Lake Lahontan covered over the area, likely when its height was controlled by overflow over Darwin Pass, which is about the same height.

Back to US-50, I completed the circle through Nevada with one last little hike joining a pair of interpretive trails outside Fallon. The interpretive trail at Grimes Point showcases the 8000 year old petroglyphs of the area. The interpretive trail at Hidden Cave showcases the geology including the tufa with its human connections.

Not being a geologist, this is somewhat beyond me:

"...were formed during the #Würmian regression period. Most geochemical and geomorphological data suggest that the deposition processes and morphologic features of the Antalya Tufa are 👉related to sea level changes and climatic forcing rather than to tectonics.👈 In addition to the geological settings of #Antalya #Tufa,..."

#Calcite can form when cool groundwater warms as it rises to the surface. Calcium carbonate exhibits inverse solubility -it's less soluble in warmer water. As a result #tufa deposits can form -like those at Mono Lake. A nice write up of groundwater carbonate deposits at:
