Understanding and definition of the YTT is constantly progressing, the term "Yukon Tanana composite terrane," or "YTCT" is used by some workers, reflecting the disparate depositional and tectonic histories being recognized in rock units within the YTT. Since 2010, some work dispenses altogether with

America to the east; it forms a significant boundary between North America cratonic rocks and rocks of the YTT and associated terranes, although displaced continental rocks are found south of the Tintina Fault

The YTT consists of polymetamorphosed and polydeformed metasedimentary, metavolcanic, and metaplutonic rocks of Upper
Paleozoic and older ages that were deposited or emplaced near the edge of the North American continental margin. Rocks in the terrane record a variety of tectonic settings and have
