Volcagenic masive sulfide deposits

Question 1

How do resources form at constructive plate margins?

Answer 1

Magma under the oceanic crust generates a hydrothermal system
Seawater is cold and is warmed up by magma an rises to surface with the spreading of the sea floor
It interacts with rocks it discharges the resources

Question 2

What is involved in an international ocean drillign campaign?

Answer 2

Large ships with drill rigs investigating sites for scientific investigation

Question 3

What happens at a trans-Atlantic geothermal sulfide deposit?

Answer 3

Black smoker system
Extended focusing and hydrothermal discharge
Forms at sulphide mounds

Question 4

How are resources discovered through drilling?

Answer 4

Reactions in the rock cause them to be altered as they move downwards from the ocean floor
As fluids move through they strip the rocks of their minerals
