Seismic spider painted green.

This unit was designed with a seperate weighted accelerometer seismic unit to replace the unit put out on November 20, During the — eruption of Mount St. Helens, portable stations, nicknamed “spiders,” installed by helicopter-sling operations were a critical volcano-monitoring tool at sites where ground crews could not work safely or where landing a helicopter was not possible.

Spiders transmit real-time data day and night, helping scientists to provide local, state, and federal government agencies with appropriate updates in the state of volcanic activity.

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.

The conventional K-Ar dating method was applied to the dacite flow from the The lava dome at Mount St. Helens dates very much older than its true age​.

Besides being distinctive, a volcanic-ash layer has four other advantages for purposes of correlation: it was laid down in an instant of geologic time; it settles out over tremendous areas; it permits physical correlation between contrasting sedimentary environments; and unaltered mineral crystals that…. Ash falls from continued explosive jetting of fine volcanic particles into high ash clouds generally do not cause any direct fatalities.

However, where the ash accumulates more than a few centimetres, collapsing roofs and failure of crops are major secondary hazards. Crop failure can occur…. Volcanic ash is also fine but more gritty, with particles up to the size of grains of rice. Cinders, sometimes called scoriae, are the next in size; these coarse fragments can range from 2 mm 0. Tephra layers are excellent time-stratigraphic markers, but, to establish a chronology, it is necessary to identify and correlate as many tephra units as possible over the widest possible area.

Because of the large number of violent volcanic explosions in Iceland, Sigurdur Thorarinsson, an…. Sulfur aerosols reflect incoming solar radiation and absorb terrestrial radiation. Together these processes cool the troposphere below. If sulfur aerosol loading is significant enough, it.

Excess Argon within Mineral Concentrates from the New Dacite Lava Dome at Mount St. Helens Volcano

Copyright by Creation Science Foundation, Ltd. All Rights Reserved. The conventional K-Ar dating method was applied to the dacite flow from the new lava dome at Mount St. Helens, Washington. Porphyritic dacite which solidified on the surface of the lava dome in gives a whole rock K-Ar ‘age’ of 0. Mineral concentrates from the dacite which formed in give K-Ar ‘ages’ from 0. These ‘ages’ are, of course, preposterous. The fundamental dating assumption ‘no radiogenic argon was present when the rock formed’ is questioned by these data.

Instead, data from this Mount St. Helens dacite argue that significant ‘excess argon’ was present when the lava solidified in Phenocrysts of orthopyroxene, hornblende and plagioclase are interpreted to have occluded argon within their mineral structures deep in the magma chamber and to have retained this argon after emplacement and solidification of the dacite.

Orthopyroxene retains the most argon, followed by hornblende, and finally, plagioclase. The lava dome at Mount St. Helens dates very much older than its true age because phenocryst minerals inherit argon from the magma.

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.
