The energy that moves sand along a beach comes from the wind-driven water waves that break upon the shore. As wind blows over the surface of an ocean or a lake, some of the wind‘s energy is transferred to the water surface, forming the waves that move through the...

Ophiolites: Ophiolites are tectonically emplaced successions of mafic and ultramafic rocks that are considered to represent fragments of oceanic or back-arc basin crust (Coleman, 1977; Moores, 1982). Units of Ophiolites: An ideal ophiolite includes from bottom to top...

Convergent Margins: Convergent margins occur where the adjacent plates move toward each other and the motion is accommodated by one plate overriding the other. In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of...

The Bouma sequence specifically describes the ideal vertical succession of structures deposited by low-density (i.e., low sand concentration, fine-grained) turbidity currents. The Bouma sequence is divided into five distinct units, labelled A through E, with A at the...
