A hydrothermal vein is composed of minerals deposited from hot, mineral-rich fluids that flow through fractures in rocks. These minerals often include quartz, calcite, and sulfides such as pyrite. The composition of a hydrothermal vein can vary depending on the temperature, pressure, and chemical makeup of the fluid involved.

What is a hydrothermal vent?

A hydrothermal vent is a fissure in the seafloor that releases geothermally heated water. These vents are found in areas of tectonic activity, such as mid-ocean ridges, and support unique ecosystems that thrive in the extreme conditions created by the hot, mineral-rich water.


Describe how a vein of silver forms from a solution.?

A vein of silver forms from a solution by vein minerals that form in fissures in the existing rock, either thru deposition by mineral saturated hydrothermal fluids, or injection of magma and subsequent cooling.

What is the difference between a dike and a vein deposit?

A dike is a tabular body of intrusive rock that cuts across pre-existing rock layers, while a vein deposit is a narrow, linear fracture filled with minerals that are precipitated from hydrothermal fluids. Dikes are igneous in origin, whereas vein deposits are often associated with hydrothermal mineralization.
