Hydrothermal Activity and Metalliferous Deposits,tal deposits on the ocean floor was based on geophysical constraints related to the Earth’s heat budget. The deficit of heat discharge on spreading ridges was thought to be the result of a discharge of hydrothermal fluid on the sea floor.thrombosis 发表于 2025-3-23 16:47:09
Book 2014es a comprehensive overview of the past 45 years of sea floor exploration. It summarizes the mineralogical and petrological composition of sea floor rocks, ocean floor volcanism in relation to the geological setting and the discovery of hydrothermal activity. In addition to learning about various scgerrymander 发表于 2025-3-23 19:34:48
An Overview of Oceanographic Exploration, after World War II in 1946, when the world’s politicians and scientists realized that in order to have supremacy over other countries and acquire knowledge of our planet it would be necessary to increase the capability of sea floor exploration.

Our Haven, Planet Earth,n years after its formation 4.1–4.7 billion years ago. Earth is the third planet in our solar system circling around the Sun in an elliptical orbit at a distance of 147–152 million kilometers. Such a distance from the Sun enables our planet’s temperature to be hospitable to animal and plant life. Amtackle 发表于 2025-3-24 05:25:00
Diving into the Abysses, Underwater visibility is limited, it is impossible for humans to breathe in water, its salty nature makes seawater denser than air (about 1300 times heavier than air), and underwater currents tend to displace any man-made engines at depth. Despite these difficulties, humans have always been attractBetween 发表于 2025-3-24 08:31:03

Oceanic Spreading Ridges and Sea Floor Creation,r the oceans and in subaerial terrain. The Spreading Ridge System is where plate divergence occurs when ascending hot material rising from the mantle creates the sea floor. The spreading ridges extend around the World for a total length of 70,000 km and a width of about 1,000–2,000 km. This system iIngratiate 发表于 2025-3-25 02:04:23
Fracture Zones and Transform Faults,that slip in opposite directions. The motion of the plates has gashed the lithosphere down to more than 4000 m deep, often exposing deep mantle material. Fracture zones vary in length from a few tens to hundreds of kilometers and are narrow, no more than a few tens of kilometers wide. The seismicall
