Monserrat and Lesser Antilles (ocean-ocean)

Back (Answer)

#11
Front (Question)

Faults (all kinds of convergent boundaries)

Back (Answer)

Thrust fault (low angle) and reverse faults (high angle) In ocean-cont very much in wedge to regional scale

#12
Front (Question)

Volcanism/mountains (Continent-continent)

Back (Answer)

Volcanism common because crust is so thick High mountains

#13
Front (Question)

Metamorphism (Continent-continent)

Back (Answer)

Low grade contact metamorphism Low-high grade regional metamorphism (depending on how deep and close to area of convergence rock is)

#14
Front (Question)

Metamorphism (ocean-continent)

Back (Answer)

Oceanic plate (subducted): Blueschist - eclogite facies Accretionary wedge Zeolite - sub greenschist

#15
Front (Question)

Volcanism/mountains (ocean- continent)

Back (Answer)

High mountains Explosive volcanism (lots of volatiles dragged into mantle wedge)
