What is hydrothermal fluid and how is it formed?

The exhibit introduces the use of real scenery created by hydrothermal fluids to recreate the special environment of underwater hydrothermal fluids. In the "seabed" surrounded by chimneys, a screen is used as a carrier to present the formation process, main distribution, and important value of hydrothermal fluids. Deep sea hydrothermal fluids, the hot flow of underwater cracks, are high-temperature fluids that can reach up to 400 ℃ when seawater is heated by underground magma. Hydrothermal activity is widely distributed in the mid ocean ridges around the world and is an important source of deep-sea resources. Hydrothermal fluids not only contain metal treasures such as copper, zinc, lead, gold, and silver, but also nurture unique deep-sea ecosystems. Deep sea hydrothermal research is of great significance for understanding geological activities on Earth, exploring the origin of life, and developing energy resources.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
