Are you suggesting there was no land prior to the Cambrian? What about the Archean Witwatersrand Basin?

ben, there are more subaerial PreC terranes than just the two mentioned above. I think you're going to have a hard time proving that part of your theory. I suggest you also look up the Mesoarchean Pongola Supergroup (South Africa), which underlie the Witwatersrand sediments.

These rocks may represent the oldest land mass on the planet.

Here's a good place to start: THE PONGOLA SUPERGROUP IN SWAZILAND by NOAH NHLEKO

Re: the oxygen is absorbed in the process of some burst of volcano
I'm sorry ben, but I'm not sure what you mean. Are you referring to lapilli, rather than lapis?

As for absorption of oxygen, do you mean oxygen in the form of O2 or any form such as in H2O?
