Hey geologists I need a bit of help with my worldbuilding.
So I'm adding dwarves to my setting but not your typical short stubby fleshy dudes. But rather short stubby rocky dudes. There are three types of dwarves upper crust, mid crust, and lower crust. They grow at different levels in the earth's crust and are made out of different rocks depending on what's available at that level. Like if they're closer to the surface they're made out of rocks and gems and such that naturally grow at that level.
Small issue though I have no idea what grows- forms? At those different levels farther or closer to the surface and I also don't know in what amounts. What's rare and what's common? I imagine diamonds don't grow in the same place as amethyst.
If you guys could help me out it would be much appreciated!
P.s. I did try googling it first but I couldn't find anything.
P.p.s. a visual representation like a rock map or something would be nice but is not required.
P.p.p.s. please don't be mean to me I'm not an expert on rocks I don't know exactly what to search for which is why I'm asking for help.
Dallol Volcanic Acid Pools
Geological one of the most active spots on Earth, the Dallol valley is a volcanic explosion crater in the Danakil Depression of Ethiopia–some 328 feet below sea level. A combination of subterranean basaltic magma (ie new sea floor) and salty water has created phreatic explosions–the latest one in 1926. These steam explosions create pockets of volcanoes, bubbling hot water pots, bright yellow sulfur fields, and expansive salt flats. Numerous hot springs are discharging brine and acidic liquid here. Widespread are small, temporary geysers which are forming cones of salt.
Dallol offers an opportunity to see the first signs of new ocean basin forming. South of the dormant Dallol volcano, rectangular salt slabs are cut and transported up into the highlands in a near endless procession of camel caravans. The salt canyons south of Dallol Mountain are some of the most impressive geological features in the area. But with the heavy geothermic activity, the basin shape, and the lack of wind, it’s also one of the hottest areas on earth. The mineral-rich pools avoid evaporation only by continuous feeding from thermal springs.
Hawai’i Vog: Volcanic/Fog/Smog
Shiprock Reprised by Wayne Pinkston Via Flickr: This is a panorama of Shiprock, the huge rock tower for which the town of Shiprock, New Mexico is named. Many photos back I posted a photo of Shipwreck from last year, and several people had expressed an interest in shooting there. We (myself, Chris Wray, Sandra Herber, and Eric Gail) shot there and ran into another group from Flickr including Willa Wei, Huibo Hou, and Wenjie Qiao. Some of their photos have been posted from the night, and it is fascinating to see how different photographers interpret what they capture. The photos vary quite a bit and reflect choices in processing and acquisition. Willa's group captured foreground photos at blue hour and as such they have more foreground detail which is beautiful. We arrived later and for the panoramas obtained a series of vertical single exposures, foreground included. This is series of 12 vertical images obtained with a 24 f1.4 Bower-Rokinon lens at 24 mm, f 1.4, 15 sec., andISO 12,800. The rock monolith is 1,583 feet, 482.5 meters high (from the surrounding plain). It is the remnant of the throat or central core of an extinct volcano, exposed over time by erosion. By the way, one of the photographers, Wenjie Qiao, has developed an excellent smartphone app called PlanIt, that helps to plan night photographs like this. Consider checking it out! Thanks for taking the time to look. Hope you enjoy! Big thanks to the wonderful Flickr family out there. Please join me at: Website Facebook Instagram Blog
