Etymology: "Oceanite" is a plain technical coinage, built from "ocean" and the suffix "-ite," which in geology is used to name rocks and minerals. The pattern is an old one: "-ite" comes from Greek "-ites," meaning belonging to or associated with, and it has been attached to place and substance names for centuries, so a rock named for the ocean where it forms follows a familiar route. The word's interest lies in its meaning rather than any surprising twist. "Ocean" traces back through Latin "oceanus" to Greek "Ōkeanos," the great river thought to encircle the flat earth in Greek mythology, so the older sense of the root was a boundary-river rather than a body of salt water. The suffix tells us nothing about the rock's composition; it simply signals that the name refers to something found in a particular setting, here the seafloor.
