The last of the benefits is that the zircon, itself, is very hard. Assuming a closed system means that nothing on the outside of the rock affected the sample. Another benefit is that zircon has been found in most igneous rocks. With the added input of energy from the sun, the leaves create a variety of sugars and other organic compounds that the tree requires.

Unfortunately, our editorial approach may not be able to accommodate all contributions. As the tree grows, the inner layers of xylem are sealed up and die, forming heartwood. This heat could vaporise massive amounts of water, some of which would condense as snow and form gigantic glaciers. Our massive consumption of fossil fuels is releasing the carbon which has been locked up in the Earth's crust for the last four or five millennia.

This would reset the time recorded by this method. And there was evening and there was morning - Day Two. To try to account for this, a radiometric dater will use many different samples and use the ones that fit the Concordia curve. The heat would also liquefy nearly molten rocks, causing vast volcanic eruptions and assist the sliding of tectonic plates during and after the Flood. It increased atmospheric pressure, making absorption of oxygen by living creatures a much easier process than it is today.

For those materials principally marine carbonates for which these conditions apply, it remains a superior technique.

For those materials principally marine

It is assumed that when the rock cools to the point that it makes the zircon, all of the lead is excluded from the zircon. Another factor which may be involved in all these events has been proposed by physicist Dr Russell Humphreys.
