Ohhh My Gosh, Thank You For Your Post About Geologic Events And Tips On Writing Them! If You Don't Mind,

Ohhh my gosh, thank you for your post about geologic events and tips on writing them! If you don't mind, can I ask you about cave systems? Some of the more commons types (mineral types and formations) vs some of the more spectacular/rare finds and the conditions for their formation?

Hello and thanks! Caves typically are formed out of limestone (a sedimentary rock). Limestone is a rock mostly made of calcite/ calcium carbonate that is formed in the ocean. Once the ocean level lowers or the land rises due to mountain building events, these rocks get exposed to the surface where rain (which is usually always a little bit acidic) will begin to react with the stone (Similar to your teeth and soda). Once this process begins it will make the caves we know and love.

There are a couple interesting things that can happen though! First, dissolving rocks means that the water is full of minerals, that means that while that water drips from the caves it will precipitate out those minerals creating stalactites and stalagmites on the ceilings and floors. This also means that they will be made out mostly pure calcite!

Another interesting thing is that because they were on the ocean floor, it means that there will be a lot of fossils present from an ancient ocean.

Ohhh My Gosh, Thank You For Your Post About Geologic Events And Tips On Writing Them! If You Don't Mind,

So, most times, the only things you will find in caves is calcite and fossils. However in some rare instances you can have salt caves, which are also sedimentary but would be associated with the drying of oceans (You would also be able to probably find gypsum in those caves as well).

Ohhh My Gosh, Thank You For Your Post About Geologic Events And Tips On Writing Them! If You Don't Mind,

Other rare and interesting caves could be formed from hydrothermal water (hot water generated from volcanic activities), this opens up a world of different things that *could* be present including metals being deposited in the stone (gold, silver, or copper). That said, this is just me inventing excuses for if you want it to be mineable.

Some natural disasters associated with cave systems being under the land would definitely be sinkholes! There can also be entire rivers that just disappear underground.

I truly hope this helps! If someone who knows more about caves sees this, please feel free to add comments!

I submit to you that the most iconic feature of any animal is either unlikely or impossible to fossilize.

If all we had of wolves were their bones we would never guess that they howl.

If all we had of elephants were fossils with no living related species, we might infer some kind of proboscis but we’d never come up with those ears.

If all we had of chickens were bones, we wouldn’t know about their combs and wattles, or that roosters crow.

We wouldn’t know that lions have manes, or that zebras have stripes, or that peacocks have trains, that howler monkeys yell, that cats purr, that deer shed the velvet from their antlers, that caterpillars become butterflies, that spiders make webs, that chickadees say their name, that Canada geese are assholes, that orangutans are ginger, that dolphins echolocate, or that squid even existed.

My point here is that we don’t know anything about dinosaurs. If we saw one we would not recognize it. As my evidence I submit the above, along with the fact that it took us two centuries to realize they’d been all around us the whole time.

You have GOT to be kidding me. They will just name volcanoes anything.

Geology of Natural Disasters and How to write them into your fictional universe.

So, you want to write about a natural disaster to advance your plot and torture your players/characters even more? Let me tell you how, accurately.

I feel like unless it is a volcano, natural disasters are a pretty slept on plot drivers, and some of them are really cool and unique! Today, I will talk to you about land slides, earthquakes (And earthquake related disasters), and volcanoes.

Landslides: Probably one I see the least in stories, but one that would be incredibly interesting to write into a plot where they believe in curses. Landslides can happen along ocean bluffs, slightly hilly areas, and highly mountainous areas, this means it is something that can happen in most landscapes. But what can trigger a landslide? Mostly all you need to trigger a landslide could be just abnormally large amounts of rain, excessive deforestation (with a little bit of rain), or an earthquake. If you don't want to use deforestation or an earthquake as a catalyst, a really cool indicator that the land is slipping and may be prone to a collapse is J hooked trees.

This indicates that there is soil creeping slowly over time, and it may lead to a major landslide.

2. Earthquakes: Probably one of the easiest things to write, earthquakes can happen anywhere, but they are most common in places that are tectonically active areas. There are about three types of environments you can expect earthquakes to be common. The first is just rugged mountains, if your landscape looks like this, you should write in earthquakes. Associated hazards could be landslides, avalanches, and large falling rocks.

Geology Of Natural Disasters And How To Write Them Into Your Fictional Universe.

The next landscape could be a thin mountain range, next to the ocean, very scenic, but very dangerous. Essentially, I am describing a subduction zone environment.

Geology Of Natural Disasters And How To Write Them Into Your Fictional Universe.

Earthquakes in these areas could equal a couple different associated disasters. Scenario one: A very large earthquake happens, and the ocean begins to recede. This is a tsunami, enough said. If you are writing a tsunami though, please, please, do not write it as a large wave, thank you. Also, a common way people are hurt by tsunami's are from them going into the ocean because they don't understand a tsunami is going to happen.

Scenario two: A large earthquake happens, your characters are in a valley and suddenly the ground begins to liquify as the ground shakes, once the shaking stops, the ground becomes solid like nothing ever happened, except everything has suddenly sunk into the now hard ground. This is called liquefaction and it typically happens in areas that have loose dirt or lots of saturated soil.

Scenario three: There are a lot of small earthquakes, they do not cause a lot of damage, but you begin to notice that one of the isolated mountains has a plume rising. Earthquakes can indicate lava moving underground and the filling of magma chambers.

Geology Of Natural Disasters And How To Write Them Into Your Fictional Universe.

The next environment that can host lots of earthquakes would be regions that have a lot of really deep valleys and small mountain ranges (not cone volcanoes), but overall seems pretty flat.

Geology Of Natural Disasters And How To Write Them Into Your Fictional Universe.

This indicates a transform fault like the San Andreas. If you want to hint at there being earthquakes in the area, you can show fence posts that are suddenly several feet out of line at a dilapidated farm or something similar.

Geology Of Natural Disasters And How To Write Them Into Your Fictional Universe.

(These earthquakes are different because they are cased from sideways movement, not an up-and-down movement this hint can only be used for this environment). Volcanoes would not be found here, but liquefaction and landslides could still occur here.

4. Volcanoes: If you thought earthquakes had a lot of information, volcanoes do too. First you have to ask yourself, what kind of volcano you want to have, what kind of eruption style? So lets break down the kind of eruptions you can have and what their landscapes look like. Hawaiian Shield volcano: This will produce a smooth fast lava, the landscape typically is pretty flat, but there will be small cones and the rocks can have a ropey or jagged texture and the rocks will be almost exclusively black to dark red.

Stratovolcanoes: These will be solitary mountains, typically, that look like perfect cones (Picture shown in earthquake section). These will have large ash cloud eruptions and pyroclastic flows, they may have some lava, but typically most damage is done from the pyroclastic flows (think Pompeii). Some hints of these, other than describing the cone features (which can be hidden by other mountains), would be to talk about petrified wood! Trees can get fossilized in the ash and I imagine it would be very strange to find this rock that clearly looks to be a piece of wood, but its a rock. Subcategory- Calderas: Used to be a large stratovolcano, but they erupt so explosively that the entire cone collapses and creates a basin.

Geology Of Natural Disasters And How To Write Them Into Your Fictional Universe.

There are a lot of kinds of volcanoes out there, so forgive me for just putting an infographic and then talking to you about these really rare types of eruptions that I feel like people should know about.

Geology Of Natural Disasters And How To Write Them Into Your Fictional Universe.

Okay lets talk about blue lava (kind of) and black lava

Geology Of Natural Disasters And How To Write Them Into Your Fictional Universe.

You will notice the lava is still red in the middle of this image, during the day these would look like a normal eruption, but at night the burning sulfur would make it appear blue. Some cool features other than this, would be that any water in the area would become very acidic and burn the skin due to sulfuric acid. This would again be really cool if you are trying to describe a 'cursed' land.

Black lava: This happens only in the east African rift I believe, but it is a carbonatite lava, but if you are writing in a rift valley (where the continent is tearing apart to form a new ocean) this might be a cool feature. The lava will cool white and will quickly erode, it makes for a very alien landscape!

Anyway as always, this is supposed to be an introductive guide for the basics of writing geology to create cool landscapes/features into dnd or fictional universes, if you are a geologist please understand my oversimplification of tectonics, I didn't want people to run away.

YOURE WELCOME!! THANKS FOR READING ABOUT THE ROCKS I THINK THEYRE REALLY GREAT

i wish i had a geologist friend who could sit me down and tell me everything about these rocks and what kind of rock it is and how they were formed and everything about them:(
