Originally thought to be 500 million years old, now clocking in at 1.3 billion
Recent crystal mineral discoveries have redated the underwater land. Or maybe the term is backdated.
Should underwater land masses and features be labeled the same way the above surface features are labeled? Zealandia would become the 8th continent. The only land above the water besides the islands of New Zealand and New Caledonia are mountain tops and the tops of mountain ranges.
It is ironic that as we begin to seriously explore the ocean floor lands, called the Abysmal Plains, the 8th continent, hardly above water, is going back underwater again. Supposedly the whole place was submerged around 23 million years ago. If we are going to be there, and driving around these underwater lands, we might stop thinking, underwater, out of sight. The average depth is 1 to 2 KM, about half the average ocean depth. However the land below the water is what you would find on the surface lands, not the typical ocean crust land.
