Daryabar Fossa is an east-west trending
troughIn geology, a trough generally refers to a linear structural depression that extends laterally over a distance, while being less steep than a trench. A trough can be a narrow basin or a geologic rift. There are various oceanic troughs, troughs found under oceans; examples include the rift along the...
