• In an 8-part series during May-June 2007, Randy Isaac (executive director of the American Scientific Affiliation) outlined principles of Integrity in Science regarding (if you read the blog entries chronologically from bottom to top) Scientific Methodology, Skepticism in Science, Fraud, Phases of Science, Removing Unconscious Bias, Nine Lives of Offbeat Ideas, and Age of the Earth; the final part explains why he in Assessing the RATE Project where he reviews RATE's book, Radioisotopes and the Age of the Earth, Volume 2.His review (June 2007) was followed (in March 2008) by a response from RATE and replies by Randy Isaac & Kirk Bertsche.

A number of processes could cause the parent substance to be depleted at the top of the magma chamber, or the daughter product to be enriched, both of which would cause the lava erupting earlier to appear very old according to radiometric dating, and lava erupting later to appear younger.

Most scientists today believe that life has existed on the earth for billions of years.

This belief in long ages for the earth and the existence of life is derived largely from radiometric dating.

The general idea is that many different minerals are formed, which differ from one another in composition, even though they come from the same magma.

The mineral makeup of an igneous rock is ultimately determined by the chemical composition of the magma from which it crystallized.
