滨线是在陆地、大气和海洋或湖泊的界面上形成的等时面。它是呈位移形式用于确定水体或地壳质量转移(海面升降或地壳均衡)的地貌地层单位,因为这是由位移速率决定的一种判定法。由于质量转移受环境支配,故特定的滨线类型和气候变化之间存在一定关系。例如,由海面升降运动引起的上升滨线和间冰期最佳气候有关,均衡作用引起的海洋界线通常与紧接在冰川消融后最大淹没有关。作为地貌地层单位的位移滨线可能与那些对环境敏感的现象有关,如古气凝胶或与冰川、河流、风成和冰缘的地形和沉积物,这就可以建立复杂的地层层序,而位移滨线可提供地区对比的依据。这种对比已借助于图表法和数值法来表
The coastline is the isochronous surface formed at the interface between land, atmosphere and ocean or lake. It is a geomorphologic unit that is used in displacement form to determine the mass transfer of water or crust (sea surface lift or crustal equilibration) as this is a decision method that is governed by the rate of displacement. Because mass transfer is dominated by the environment, there is a relationship between the specific coastline type and climate change. For example, the rising coastline caused by sea surface movements is related to the best climate during the interglacial period. The ocean boundary caused by the equilibria usually relates to the maximum submergence immediately after the glacier ablation. Displacement coastline, which is a unit of geomorphologic units, may be related to those phenomena that are sensitive to the environment, such as paleogels or topography and sediments from glaciers, rivers, wind and ice margins, which create complex stratigraphic sequences, The displacement of the coastline can provide a basis for regional comparison. This comparison has been charted and numerical methods
