My dad says Dolomite and Limestone have the same essential chemical make up, but dolomite has been placed under pressure.
Animatronio
Limestone can dissolve in plain water, while dolomite requires a bit of acid to help, so limestone's probably a bigger contributor.
a1104477
Actually H20 combines/dissolves CO2 to form a weak acid that is what dissolves the limestone. Similarly dolomite is susceptible to the acid.
Ah, yes. Been too long since geology 101. Dolomite is susceptible as I recall, but since it has a mg cation in addition to a Ca cation (1/2)
it is somewhat less vulnerable than limestone. Dolomite had to be powdered to fizz in the lab while limestone fizzed readily. I think. (2/2)
But apparently Guatemala has more dolomite than limestone, so I was double-wrong.
ha, not an issue. I didn't know the basic geology of Guatemala either and I'm a just qualified geophysicist, in Australia.

Volcanic rocks don't dissolve in water. Limestone readily does though.
jackers
Yeah I was thinking it is more like a Karst type of geology
Pumice will though. It if is unconsolidated and not solid rock, it can be washed away through pipe leaks and storm water run-off.
But something has to give underneath it. It could be karst cover with pumice...
Kittyboop
I was thinking this too, not sure OP actually knows Geology.
OP is right. These sinkholes were caused by human activity and not nature. The storm water washes away the loose pumic and a hole opens up.
I don't, but it's not Limestone and it doesn't dissolve. It mechanically washes. Check @ginjninj 's link below.
This is actually really interesting, thanks for the sauce!
so one way or another, the city is currently sitting on what is basically a giant dirt 'bridge', and it's waiting for the wrong jolt.
