Radioactive dating of moon rocks

Interweaving the relative time scale with the atomic time scale poses certain problems because only certain types of rocks, chiefly the igneous variety, can be dated directly by radiometric methods; but these rocks do not ordinarily contain fossils. Overview. By their chemical nature, rock minerals contain certain elements and not others; but in rocks containing radioactive isotopes, the process of radioactive decay generates exotic elements over time. The first frame of a 3D movie flyover of Tycho Crater on the Moon as seen by Kaguya. Tycho is 85 kilometers wide. It displays the classic terraced crater walls and central peak of a complex crater.

How Can Radioactive Dating Be Used To Determine The Age Of Rocks? Because of this, certain mineral crystals within a rock will incorporate different elements into their structure based on their chemical differences. Some gave virtually zero ages, although the geologic evidence suggested that devitrification took place radioactive dating of moon rocks after the formation of a deposit. The assumption of quantitative argon retention is particularly inappropriate for the lunar rocks. However, a recent real time study by Riebe et. This statement contains several serious errors. Cunitz Crater is the Lava plains are found here and elsewhere in the solar system.
