Granitoids
... A few broad generalizations: 1) Most granitoids of significant volume occur in areas where the continental crust has been thickened by orogeny, either continental arc subduction or collision of sialic masses. Many granites, however, may postdate the thickening event by tens of millions of years. Ima ...

Seafloor Spreading
... In contrast to the youngest or newest seafloor rock found at mid-ocean ridges, the oldest rock is found at or close to trenches. The oldest seafloor rock is “only” about 180 million years old. Many continental rocks are much older than this; the oldest continental rock is over 4 billion years old. T ...

Tectonics is derived from a Greek word that means “to build”. The theory of Plate Tectonics, which was not widely supported until the late 1960’s, refers to the ...
