Okay, if I was voting on about any other campaign line this year, #corundum vs #lawsonite would be easier. Or at least probably less boring. 
Neither of them are chaotic at all - as far as minerals go, they're upright, goody-two-shoes grasping their pearls (carefully, because they're both much higher on the mohs scale than pearls!) at how chaotic some of these other minerals are. (c) #MinCup23
#corundum as a gemstone is cool! As a mineral... I mean it has some industrial uses as an abrasive, but other than that... 
#lawsonite is metamorphic, characteristic of low heat and high pressure at plate boundaries, and very hydrated - so it tends to drag water molecules around with it. You'll also find other blueschist minerals like #kyanite where lawsonite often is. (c) #MinCup23
(Amusingly, despite being common in blueschist formations (I think that's what that meant), #lawsonite is not actually blue. It looks pretty boring really. I think the blue part of that comes from the fact #kyanite is often blue and speckled all thru. Iirc. I didn't get off track for once in my life today lolol.)
Anyway just for sheer on the grand scale I guess metmorphism is chaotic, I'll vote Lawsonite! #MinCup23
At the risk of losing a vote for lawsontie…which I support.
Corundum is also a metamorphic badass…and granulite facies means it is super high temperature.
Blueschists (lawsonite common mneral) are badass roller coaster rocket ships to the subsurface…slamming into the continent from mid-ocean ridges and dragging sediments and water into the upper mantle. The excess water helps to drive the volatility that gives us stratovolcanoes such as the Andes, Cascades, Japanese volcanoes….
okay but see I think volcanoes are super neat so that just means I voted both for chaos (geologically, what's more chaotic than a volcano (or an earthquake but shhh)?) AND a lifelong nerdy fascination with volcanoes. Win/win!
