Kinggath told me it was cool if we all co-operated on figuring out the Industrial Revolution Tech Tree together so here's what I got:
Also let me know if you've discovered anything else and I'll try to update the list.
I need help figuring out what the tech dependencies are for some of the higher tier industries
Note: to upgrade, their stockpile requirement and possible tech dependency needs to be met as well as the 5 in-game day waiting period
Edit: Lystraeus made a great spreadsheet.
Iron Mine - stockpile: 50 Mined Ore (can be mix of any)
----Steel Mill - stockpile:400 Steel, requires Lumber Mill to upgrade
--------Tool and Die Shop (Allows lvl4 farms, makes tools?)
--------Munitions Factory (Makes ballistic ammo)
----Nuclear Enrichment Facility - stockpile: 200 Nuclear Material, requires Hazmat Processing to upgrade
--------Nuclear Arms Factory (-20 water, -20 power, -50 happiness, makes mini nukes, MIRV launchers and fatman launchers)
--------Nuclear Power Plant (+150 power, -30 happiness)
Community Well - stockpile: 50 Dirty Water
----Brewery -stockpile: 200 Beer (makes beer and happiness. Drink from a tub!)
--------Distillery (makes better liquor and +50 happiness)
--------Chem Factory - requires Medical-Grade Plastics to upgrade (makes jet)
----Pumping Station -stockpile: 200 purified/dirty water (+30 water)
--------Hydration Research Lab (Not sure what this does, only got 1 bottle of Nuka-Melon from it)
--------Filtration Plant - requires Coal Mine to upgrade (+50 water)
Lumber Mill - stockpile:100 Wood
-----Coal Pit - stockpile:200 Coal Lump
---------Flare Factory (Makes flares, not sure about signal flares though)
---------Coal Power Plant (+50 power, -30 happiness)
----Paper Mill - stockpile:200 Paper (Makes paper(cloth))
--------Magazine Press (Makes perk magazines)
--------Local Newspaper (Allows crafting of newspaper stands and makes New Bugle newspaper)
Oil Well - stockpile:50 oil
----Crude Refinery - stockpile: 100 Processed Fuel
--------Fuel Depot (Increases tax income by 10%, not sure what else)
--------Microfusion Garage - requires Tier 3 Nuclear
----Plastics and Polymers - stockpile:200 Plastic
--------Medical-Grade Plastics (Makes sterilized plastics (misc item cant sell), and happiness)
--------Advanced Weaponry Facility - requires Microfusion Garage to upgrade
Scrapyard -stockpile: 100 scrap (mix any)
----Crusher - stockpile: 160 Aluminum + 40 scrap (e.g. 160 Aluminum + 40 wood)
--------Hazmat Processing (I'm guessing makes nuclear material)
--------Remelting Facility - combine any amount junk with 3 processed fuel in fuel tank for 1.5x material
----Scrap Processing - stockpile:??? (generates uncommon materials)
--------Tech Salvagers (generates rare junk)
--------Military Salvagers (generates random weapon mods and grenades)
