‘Ages’ obtained for the lava dome of Mt St Helens
In the past two months or so the dome-shaped formation of rock in the crater has been developing a large bulge, and frequent plumes of gas have been seen rising from the crater. These are clear signs of volcanic activity and they are very similar to what was seen before the eruptions of Latest reports tell of a steam plume rising passively and drifting south and south-westward over the crater rim.
The plume occasionally contains minor ash, which falls in the crater and on the southern flank of the volcano, darkening the new snow.

Radiometric Dating Does Work!
History – Mt. Mount St. Helens, located in southwestern Washington about 50 miles northeast of Portland, Oregon, is one of several lofty volcanic peaks that dominate the Cascade Range of the Pacific Northwest; the range extends from Mount Garibaldi in British Columbia, Canada, to Lassen Peak in northern California. Geologists call Mount St. Helens a composite volcano or stratovolcano , a term for steepsided, often symmetrical cones constructed of alternating layers of lava flows, ash, and other volcanic debris.
Composite volcanoes tend to erupt explosively and pose considerable danger to nearby life and property.

More information on Mount St. Mount St. Helens has been mostly quiet since its most recent dome-building eruptions ended in January Helens itself. Cynthia Gardner, a scientist at the U. We saw the cone rebuild itself over a century or a century and a half. Yet since the eruption, she said, the mountain has rebuilt only 7 percent of its pre-eruption mass. Helens up close since Back in his lab, the rocks are sliced thin, studied under powerful microscopes and dated using radiocarbon dating or, for rocks older than 20, years, argon dating.
They hold a record of volcanic activity stretching back thousands of years. The rock specimens document that the explosive eruption, triggered by an earthquake and the largest volcanic landslide in history, was part of a cycle that has repeated itself over millennia.

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. This calls the whole radiometric dating scheme into serious question. 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. Lava erupting earlier would come from the top of the magma chamber, and lava erupting later would come from lower down.
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. 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.

Geochemist Meyer Rubin, who predicted the Mount St. Helens eruption, dies of dating, mass spectrometry, climate science, archaeology and water. “This volcano has had lava flows and explosive rock eruptions,” Rubin.
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.
The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons. First, it provides no evidence whatsoever to support their claim that the earth is very young.
The stirring on the mount
And the ages assigned to the layers were derived from rock age years assumptions — not from the scientific facts, — as the column dating established long before we even had radiometric dating. Yet the column and its assumptions are used along with index fossils to assign helens to sedimentary rock layers and which in turn is mount to date any work in that rock layer. Unfortunately, uniformitarianism has gripped geology academia and no other viewpoints are allowed.
This evolutionary assumption has become a naturalistic religion, an ideology established already before The published his book in.
