Timing and mechanism s of subduction and exhumation in the Hellenides: Structural and geoc hronological constraints from Andros and South Evia

The G reek mountains were formed in several phases

The Greek mountai ns were not formed during a single, prolonged geological process, but through several phases in which rock was pushed deep into the Earth and later rose back to the surface. This is evident from the doctoral research conducted by geoscientist Shijie Shang on rocks on the Gree k island of Andros and in southern Evia. The results shed light on ho w the movement of tectonic plates over millions of years has shaped t he current landscape.

Shang studied what are known as subductio n and exhumation. During subduction, rock is carried deep into the Ea rth by the movement of tectonic plates, while during exhumation, it i s subsequently brought back toward the Earth’s surface. By combinin g field observations with the dating of individual mineral grains, Sh ang was able to distinguish between different phases in this complex history.

One of the most important discoveries is a previously undescribed fault system on Andros: the Andros Detachment. This fault system played a role in bringing deeply buried rocks to the surface. In southern Euboea, Shang also identified a new geological unit and was able to revise the relationships between different rock sequences .

Shang’s research also shows that mountain-building processe s did not occur simultaneously throughout the region. The times when rocks were deeply buried varied from north to south. This provides a more accurate picture of the development of the Hellenides, the mount ain system associated with the convergence of the African and Eurasia n plates.

Rocks as the Earth’s Archive

The results are not only important for the geological history of Gre ece. Rocks can contain traces of multiple events that occurred millio ns of years apart. When an entire rock sample is dated as a single un it, it can be difficult to distinguish between these different events . By dating individual mineral grains, researchers can better disting uish between different phases and construct a more reliable geologica l timeline.

This knowledge helps scientists better understand h ow the Earth’s crust and mountain ranges evolve over long periods o f time. Furthermore, the approach used in this research can be applie d to other regions with complex geological histories. In this way, th e research contributes to a more accurate understanding of the proces ses that shape the Earth’s crust—and ultimately, the landscapes a round us.
