INDIAN GEOGRAPHY

Detailed explanation-1: -The solutions introduce silica and iron, which combine with the calcium and magnesium in the parent rock to form silicate minerals such as diopside, tremolite, and andradite. The hydrothermal solutions may also deposit ore minerals of iron, copper, zinc, tungsten, or molybdenum.

Detailed explanation-2: -In their simplest form, hydrothermal solutions represent water that has been heated to some temperature above ambient surface temperature as a result of natural geologic processes. Often, hydrothermal solutions contain significant amounts of dissolved gases and solids in addition to water.

Detailed explanation-3: -Hydrothermal deposits refer to the accumulation of minerals in fractures and cavities resulting from the circulation of hot waters in the Earth’s crust. Magma releases hot fluids (water and gases) as it cools but can also heat circulating groundwater.

Detailed explanation-4: -Hydrothermal fluid forms as seawater are modified through interactions with heat and the earth’s crust. These fluids emanate back into ocean water at hydrothermal vents on the seafloor.
