Metasedimentary rocks are formed from the metamorphism of pre-existing sedimentary rocks, such as shale, limestone, or sandstone.

Metasedimentary rocks are formed from the metamorphism of pre-existing sedimentary rocks, such as shale, limestone, or sandstone. Metavolcanic rocks, on the other hand, are formed from the metamorphism of pre-existing volcanic rocks, like basalt or tuff.
The key difference lies in their protoliths (original rocks). Metasedimentary rocks were once sedimentary rocks that experienced changes in temperature and pressure, leading to their transformation into metamorphic rocks. In contrast, metavolcanic rocks were originally volcanic rocks that underwent metamorphism due to increased heat and pressure.
The metamorphism process can alter the mineral composition, texture, and overall appearance of both types of rocks, creating new minerals and structural features that distinguish them from their original counterpart.

In geology, a suture zone refers to a boundary where two distinct tectonic plates or terranes have collided and fused together over millions of years. These zones are characterized by complex rock formations and may contain remnants of the ocean floor that once separated the plates. Suture zones areRead more
