縫合帶

縫合帶，也稱「縫合線」，地質學術語，是指大的斷層區域，分隔開了具有不同板塊構造起源的地體、地質構造單元。^[1]這一術語源自外科學的引申使用。

縫合帶的露頭的寬度從幾百米到若干千米。可以是網狀的糜稜岩剪切區或脆性斷裂區。縫合帶通常是火成岩侵入與透鏡狀的（英語：Lens (geology)）構造，在岩石學上屬於從深成岩到蛇綠岩組分。

The geophysical definitions are generally based upon the integration of a physical response over the thickness of the crust, whereas the geological definition is almost always as a line or zone at the Earth's surface."
