A: It’d be rude to examine his texture, so consider his origin & path.
He’s evolved under immense pressure, dramatically changed yet never shattered, and doesn’t explode even when provoked.
Metamorphic.
You can’t do that with the Rock.
Even before you debate if he’s getting more or less hot with age.
The Rock has a juvie record, got cut from his Big Break as a football star, repeatedly got boo’d (& injured) under multiple WWF names, and did not shatter. Somehow.
They just get shinier & more distinctive.
The Rock does not appear to have stripes or banding, so I’m going with non-foliated. That means he’s likely gotten harder with progressive metamorphism.
Do not poke (or lick) without consent.
I’ve yet to observe The Rock under natural lighting, so it’s hard to distinguish if he’s just lightly foliated. He may possess slaty or phyllitic cleavage, aligned platey minerals too small to see yet enough to produce a distinctive shine.
But that’d imply less pressure.
Again, it’d be rude to subject the rock to a geochemical analysis, but again, we can look to origin.
US & Canadian dual citizenship = could be anything.
Somoan heritage = volcanic islands with reefs.
But The Rock consumes lemons without dissolving, so nah.
Sand + pressure = quartzite
He’s Hard AF, but not nearly that common
Subducted talc = soapstone
But that’s extremely soft.
And all are low pressure. Which doesn’t fit at all.
I said The Rock did not appear to have banding.
It’s more accurate to say The Rock didn’t USED TO have banding.
He’s been getting more striped over time.
He’s acquired banding with pressure.
He was low-grade slate as a footballer, a shiny phillite as a WWF star, transitioned to shist during his 2003 heritage tattooing, & is now gneiss.
How nice!
He’s a foliated metamorphic, transitioned to gneiss in 2017. He’ll likely continue to stay gneiss for the remainder of his career, potentially acquiring more banding.
Should he start getting hot-yet-squishy, he may transition to migmatite.
1. Metamorphic rocks are not identified by taste, so licking The Rock will not confirm this classification. Licking is primarily diagnostic on water soluable rocks so your tongue can taste them. He doesn’t dissolve when submerged.
And he’s on the Do Not Lick list:
As a foliated metamorphic, temperature is irrelevant to his classification provided he’s below his melting point. He can be both.
If he’s too hot, he’ll transition to partial-melt migmatite on the metamorphic/igneous boundary.
Multi-generation celebrity wrestling status provided tough components. Rocks are most resilient under their formation conditions, so his Canadian/Samoan heritage enhances resistance to a wide temperature range.
Based on his fav quote & goofy humour, I suspect he finds geologic jargon puns irresistible as the rest of us.
