Due to the insufficient supply of magma and the low frequency of tectonic activities, the hydrothermal activity in the slowly expanding mid-ocean ridge is usually long-lived and multi-stage, with the potential to form large seabed sulfide deposits.
Due to the insufficient supply of magma and the low frequency of tectonic activity, hydrothermal activity in the slow-expanding mid-ocean ridge is usually long-life, multi-period, with the potential to form large seabed sulphide deposits.
Due to the lack of magma supply and the low frequency of tectonic activity, the hydrothermal activity in the middle ridge of the slowly expanding ocean is usually long-lived and multi-stage, which has the potential to form large submarine sulfide deposits.
