Triple junction definition geology

WebA triple junction is the point where three tectonic plates meet; the boundaries of these plates are characterized by divergence, causing a rift zone or spreading center; a transform fault; or convergence causing subduction or uplift of crust and forming mountains. WebTriple junctions are points on the Earth's surface where the margins of three different plates meet. There are three types of plate margins: (1) ridges (R); (2) trenches, or Himalaya type (formed by the collision of two continents), (T); and (3) transform faults (F).
