/vt/ - Virtual Youtubers

I vaguely remember seeing a post asking what kind of rock /who/ would have as building material, but I can't find the post in question now. It might just be my memory playing tricks on me, but here it is:
>Geology
The majority of /who/ is defined by the continental collision east of it, which results in half of /who/ being Himalayan-type orogen, and the other half being affected by it.
>Igneous rocks
Because both of the plates involved are continental plates, their lower density results in a relative lack of volcanism, which means that most igneous rocks in /who/ would be plutonic (forming from magma) in nature. In Himalayan-type orogen, they tend to be felsic (rich in silicate), which means the majority of building-type rock would be granite and diorite. They are fairly famous as building blocks, but it should be noted that their valued toughness also means they're *very* labour intensive to process in pre-modern times. While granite buildings did exist since Medieval times (or even ancient times if you consider pyramids to be buildings), you are probably not going to use them for mundane buildings. This is more common in the mountaineous east.
>Sedimentary rock
Because of how the Council Plate rotates, the land that will be /who/ was likely once underwater. As a result, there will be some buildup of sediment from the ancient seafloor. While not as significant as places like /risu/ or other passive margins, /who/ will likely still have access to sedimentary rock, especially closer to the coastal region where tectonic folding is not significant enough to cause the next section in this post. Among them, marl, dolomite and limestone are the most common building material, although it should be noted that they're more common as *ingredients* of building material. Still, they are easier to work, and entire cities have been built with them - the most famous ones being Cairo (which was built from limestone harvested from the pyramids) and Jerusalem.
>Metamorphic rock
The pressure put upon the rock by the orogen to the east can often result in the rock being transformed ("metamorphised") into other types of rock. For Himalayan-type orogen, the type of metamorphism is usually high-pressure but low-temprature, meaning that it would be dominated by blueschist and eclogite. Apart from similar rock types from above, the most notable metamorphic rocks that are used as building materials would be slate and marble, which probably require no introduction.
