Many creationists believe the earth was created by almighty God some thousands of years ago. Evolutionists, on the other hand, maintain that the earth is about 4. How can there be such a vast discrepancy between these dates? Many Christians find this a real problem for they think that the evolutionary scientists cannot possibly be wrong. But they can. The rock that made up the third lava dome on Mount St Helens is dacite— a fine-grained volcanic rock that contains a sprinkling of larger visible crystals, like currants in a fruit cake. Dacite lava is too viscous to flow very far and so it just piles up around the vent of the volcano and forms a hill-like dome plugging the volcano. This dacite lava contains the element potassium and since potassium contains a radioactive isotope can be subjected to potassium-argon radiometric dating.

Introduction: Rocks and fossils do not come with dates on them. In fact, the very concept of strata representing long ages does not come from the rock strata themselves.

‘Ages’ obtained for the lava dome of Mt St Helens
Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Some so-called creation scientists have attempted to show that radiometric dating does not work on theoretical grounds for example, Arndts and Overn ; Gill but such attempts invariably have fatal flaws see Dalrymple ; York and Dalrymple Other creationists have focused on instances in which radiometric dating seems to yield incorrect results.
In most instances, these efforts are flawed because the authors have misunderstood or misrepresented the data they attempt to analyze for example, Woodmorappe ; Morris HM ; Morris JD Only rarely does a creationist actually find an incorrect radiometric result Austin ; Rugg and Austin that has not already been revealed and discussed in the scientific literature.

Here I want to concentrate on another source of error, namely, processes that take place within magma chambers. To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating. Radiometric dating is largely done on rock that has formed from solidified lava. 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. Such processes can cause the daughter product to be enriched relative to the parent, which would make the rock look older, or cause the parent to be enriched relative to the daughter, which would make the rock look younger.

The ‘ages’ obtained by radiometric dating for the rocks from the third lava dome on Mount St Helens — unquestionably formed since the May eruption.
Until the 18 May eruption of Mount St. Helens, a debris fan and adjacent forest downslope from the dacitic Goat Rocks dome, on the north flank of the volcano, contained evidence that the dome was active in or The fan was destroyed by the debris avalanche of 18 May. Before , the oldest tree cored on the debris fan showed that the fan predated by a few years. An anomalous series of narrow rings that starts with the ring is present in cores from two older trees adjacent to the fan.
These ring-width patterns imply that these trees were damaged in late or early by flowage material from the dome; the trees were probably singed by an ash-cloud surge that originated on the dome as a hot-rock avalanche. Several lines of evidence suggest that the anomalous ring patterns record tree injury by surge, rather than by lahars or nonvolcanic causes climate or insects.
First, comparable ring patterns formed in all sampled trees that survived the 18 May surge, but formed in only a few sampled trees abraded or partially buried by 18 May lahars. Second, a cm fine-ash layer, consistent with either tephra fall or surge emplacement, was present on the s forest floor; yet the lack of similar tree-ring responses to tephra fall shows that such minor tephra fall could not have caused the ring patterns.
Third, identical narrow-ring patterns are absent in control trees further from the volcano. The ring patterns of the trees adjacent to the Goat Rocks fan provide the first field evidence that the dome was active in late or early Thus, the new tree-ring dates confirm stratigraphic evidence for the youth of the activity of the Goat Rocks dome.
