I've looked everywhere for an answer to this, resources?

What do each of the symbols in the recourses stand for? I am trying to guess which number corresponds to which resource and it’s really confusing. I don’t remember there being any sort of indicator when I started my first game today which symbol stood for what, and I can’t find the answer anywhere in the game or online. Can anyone help me?

From top to bottom:
Brimstone
Crystal
Essence
Granite
Power

Thanks so much. I was so confused.
