There is more than one batholith in California. You can find accreted terrane in northern states.

How does a geologist determine if a rock is part of an accreted terrane?
A geologist can determine if a rock is part of an accreted terrane by analyzing its composition, age, and structure compared to the surrounding rocks. Signs of deformation and metamorphism that are distinct from the surrounding rocks can also indicate that a rock has been accreted from a different tectonic plate. Additionally, examining the presence of specific minerals or fossil assemblages can provide clues to the origin of the rock.
What is the term for a piece of crust which has been in a collision along a convergent crustal boundary and become accreted to another crustal plate?
A terrane is the term used to describe a piece of crust that has been in a collision along a convergent crustal boundary and subsequently accreted to another crustal plate. Terranes are distinct geological units with their own history of formation.
What is the process of accretion?
This is when a bit one tectonic plate breaks off and sticks to (accretes) to another plate. Here are some sentences.There is an area of accreted terrane on nearly every tectonic plate.We studied accreted terranes in class, and I thought the teacher said "terrain."An accreted terrane keeps the characteristics of the original plate rather than taking on new ones.
What do geologists call small accreted crustal fragments that have a geologic history distinct from adjacent blocks?
Geologists refer to small accreted crustal fragments with a distinct geologic history as exotic terranes. These terranes often have different rock types, structural features, and ages compared to the surrounding blocks due to their separate tectonic origins. Exotic terranes are crucial in understanding the complex geological history of a region.
An exotic terrane created by a seamount accreted to a continental margin would be composed of what?
An exotic terrane formed by a seamount accreted to a continental margin would likely be composed of a mixture of oceanic crust, sediments, and igneous rocks from the seamount. This collision and accretion process can introduce a variety of rock types, such as basalt, volcanic rocks, and marine sediments, which are then incorporated into the continental margin.
