September 2, 1806, a landslide destroys the Swiss village of Goldau and triggers an "alpine tsunami" killing 500 people. It is the first natural disaster investigated in detail by #geologists ⚒️

Hey @alden have you and other #bayarea #geologists seen this rock-inspired bake off KQED is hosting next month? https://www.kqed.org/event/3408

Would you enter?!

Thank you to the #geologists who recommended a good rock hammer last Christmas. It’s getting a good workout in Montana US this summer.

My wife is in #Lyon, #France eating good food and talking to other #geologists while I am here having to work. Tomorrow she is going to #Chamonix while I am commuting to the office. I'm jealous as heck, but more than that I am so proud of all of her hard work to get to where she is now.

So have already had interesting convos today about singing #rocks (see link for example), Guano Islands Act, and am pondering scientists propensity to use all their senses (#geologists lick rocks; #biologist keep lists of phyla they have eaten; #chemists test drugs on themselves; what do #physicists do?

June 26, 1824, birthday of physicist William Thomson, better known as Lord Kelvin. His used thermodynamics to calculate #Earth's age* even if #geologists complained that "physics cannot be applied to #geology"* (*not exactly true) ⏰

@GaldraCori try searching hashtags like #geologists and #geology?

During her lifetime she was barred from even attending meetings of the Geological Society of London (let alone applying for membership) because of her sex & many wealthy "paleontologists" published claims of discovery based on having purchased fossils from Anning & other fossil hunters (neglecting to mention Anning's name or contribution). Nonetheless, many contemporary #geologists & #paleontologists became so impressed with her knowledge that they would visit her to consult on the anatomy &

@suw you might want to ask Earth scientists as well, or does is specifically have to be ecologists? #geology #geologists #earthsciences #hydrologists

[although my postgrad was in geology and I am licensed in the field, it has been a number of years since I worked directly in a geologic discipline; that said, I very much like to try and keep up with ‘things geology’…]

I've a question for #geologists and anyone else who might know: what is the term for the process that causes rocks to come up into newly tilled soil, say, in a field? Every year, even though each spring all the existing rocks are removed? It reminds me of capillary action, but I think that pertains to liquids, not solids. A 2nd question is, are the rocks pulled? pushed? or drawn upward by the condition of less pressure? And if it's that, why does rock move to less pressure?
#Rocks #PickingStone

#Geology Question of the day: Why do #geologists expect to see increasing chloride content in surface waters around pending magmatic #eruptions. I did not immediately know the answer to this.

The average chlorine content of basalts is only 0.014%.

A large fraction occurs in hydroxyl minerals such as biotite and hornblende; These minerals may contain several tenths of a per cent of chlorine. Some chlorine is also present as chloride in liquid (aqueous) inclusions.

Chlorine does not show any marked trend in the differentiation of the common igneous rocks. Since it is an element of well-developed atmophilic and hydrophilic characteristics, a general lack of correlation between chlorine and the major and minor constituents of rocks is not unexpected; an appreciable, perhaps large, fraction of the chlorine in a magma escapes on crystallization.

Few elements (compared to chlorine) have siderophilic, lithophilic, hydrophilic, and atmophilic properties all developed in comparable degree.

I remember when we just called them ROCKS, and now they all have fancy names, 😎
"Geology On"
Geology N Roll"
And the famous geologist Joni Mitchell once said. "I've looked at rocks from both sides now, from up and down and still somehow,.... I really don't know #Rocks at all ♪

I wonder who I could ask about these strange rocks I've been finding? Anyone? 🤔 Goood morning @Judeet88
What am I looking at? Any Idea?..
Don't say Rocks, I already got that far 😂

Do any #PNW / Western US #geologists have thoughts about how relevant are the older editions of the Roadside Geology series from the late 1970s/1980s? A big book sale fundraiser is going on this week in town and they have a bunch for $2 each ($1 each if still left tomorrow)

We have a recent Washington book, and an old Oregon one. My 4yo really loved us reading aloud from it on our Oregon coast road trip this summer, but it seemed a bit dated (I have never formally studied #geology)

Once #Apollo landed on the #Moon, #geologists wanted #samples. Such samples needed to be kept #safe, both from the atmosphere aboard the #LEM or #CSM or #Earth, and the keep the #Earth safe from any unknown or unknowable #pathogens in them. So the #lunar samples were stored in #airtight containers and remain sealed until they are studied. Apollo confirmed what most #scientists already believed though: The Moon is dead. There are no pathogens there.

I know that #geologists like rocks, so here are some sure to be crowd pleasing photos of the local #volcano park (the #volcanoes are #maars): a lava flow, the #volcanic #rock named after the town, and an impressive looking #intrusion.
