Geologists assert that older dates are found deeper down in the geologic column, which they take as evidence that radiometric dating is giving true ages, since it is apparent that rocks that are deeper must be older.

But even if it is true that older radiometric dates are found lower down in the geologic column, which is open to question, this can potentially be explained by processes occurring in magma chambers which cause the lava erupting earlier to appear older than the lava erupting later.

But at the same time, it will be enriched in the elements contained in the later forming minerals, namely sodium and potassium.

Further, the silicon content of the melt becomes enriched toward the latter stages of crystallization.

This left branch is called a discontinuous reaction series because each mineral has a different crystalline structure.

A pioneering investigation into the crystallization of magma was carried out by N. At successively lower temperature, other minerals begin to crystallize as shown in Figure 3.6.

Lava (properly called magma before it erupts) fills large underground chambers called magma chambers.

Most people are not aware of the many processes that take place in lava before it erupts and as it solidifies, processes that can have a tremendous influence on daughter to parent ratios.

These long time periods are computed by measuring the ratio of daughter to parent substance in a rock and inferring an age based on this ratio.

This age is computed under the assumption that the parent substance (say, uranium) gradually decays to the daughter substance (say, lead), so the higher the ratio of lead to uranium, the older the rock must be.

  1. But what's even lamer: when some outsider tries to use the language, without the ability to contribute. My friends and I would discuss how she was trying to speak like us, and it got to the point where I bristled every time I heard her speak one of our made-up words. Make sure you cater what you wear to what you're doing. I make myself look really picky and difficult to get to.
