Why would geologic mapping be difficult in an area dominated by accreted terranes?
A)The geology is so similar that it would be difficult to determine terrane boundaries
B)Each terrane is geologically distinct, but also highly deformed
C)Isostatic rebound would result in gravitational collapse to make them indistinct
D)Terranes are very old and terribly eroded

Accreted terranes are usually collisional zones where multiple tectonic plates have collided, creating distinct geological units with different ages and compositions. These terranes are also highly deformed due to the pressure and temperature changes during the collision process, making it difficult to identify and map individual units. Additionally, the boundaries between terranes are often obscured by faulting and deformation, further complicating mapping efforts.
