question 12 (0.83 points)
contact \aureoles\ of non - foliated rock are most commonly formed in the upper crust in areas affected by
water soluble minerals
greatest water - depth
magmatic intrusions
convergent centers of subduction
groundwater

Explanation:

Contact aureoles form when existing rock is heated and altered by nearby molten rock. Non-foliated contact aureoles are created by the thermal metamorphism from magma bodies pushing into the upper crust, which matches magmatic intrusions. The other options do not drive this type of metamorphic rock formation.

Answer:

magmatic intrusions
