The minerals get into the ocean by when it rains the minerals on land flows into the ocean.

idiochromatic minerals are those minerals which have fairly constant colour. they are hard minerals and they posses only in metals
Soft or hard water has to do with the amount of dissolved minerals in water and what those minerals are. "Harder" water has more dissolved minerals (like calcium.)
Calcium makes them hard.

hydroxyapatite
Mineral content. more minerals means hard
minerals make bone hard and are very important in blood composition
Dissolved minerals in the water. In most cases it is better to water your garden with hard water instead of treated water. The plants typically like the minerals found in hard water.
