  • Marine sediments contain a host of microfossils that reflect the plankton of the past and provide records of ocean changes.

  • Marine sediments can conserve phytoplankton shells that are exported to depth.

  • Marine sediments are generally most complicated because of the co-occurrence of organic matter, carbonates and Fe sulphides.

  • Marine sediments dating to MIS 3 have been described in the glaciated region of Russia and Europe.

  • Marine sediments dating to MIS 3 are uncommon in North America and are often less reliably constrained than similar sites in Russia and Europe.

  • But when we consider some of the high prophetic meanings connected with the Grand Gallery, and of that well out of which it takes its beginning, we would rather infer that the builders themselves broke out that ramp-stone, or sealed on that fragment in a way indicative of violent bursting out from below, as part of the great intention and teaching of the mighty fabric.
