Geological Dating

Those studying geology and those working as geologists in geological surveys, universities, and private industry will enjoy this article by Brett Smith from a 2008 Journal of Creation. It may be a bit of a challenge:
The current treatment of young-age creationists in the scientific community and society at large is unfair and unwise. Scientists and [...]

I was encouraged to receive an email from a geologist friend who has been working in mining and mineral exploration most of his life.
A quick note to thank you for the list of references you sent. My interest in this topic came from looking at the timing of many of the landforms that one [...]

It is quite simple to understand how radioactive dating works when you think about it.

It is impossible to measure the age of anything by making observations and measurements in the present.
Before any age can be calculated, unprovable assumptions about the past are needed.
After an age is calculated, we cannot know if the number means [...]

On Sunday evening 5 June 2011, I was on a panel at a church north of Brisbane answering questions on evolution and the age of the earth.
I represented the biblical young-earth position.
The three other scientists on the panel held to various old-earth views, and were:

Jonathon Cramb, who is completing a PhD in palaeontology.
Dr [...]

It is often claimed that the Hawaiian Islands provide an impossible problem for biblical geology and the young earth. One skeptic put it this way:
 
The key observation that must be explained away is the linear relationship between the measured ages of these islands (more than 100 independent measurements) and their distance from the volcanic hotspot. [...]

These solid spherical stones, scattered over the beach on the South Island of New Zealand, look like the remains of a monster game of marbles. (Click image to enlarge.)
They are spectacular examples of concretions, which form when a mineral precipitates from the ground water cementing the loose grains of sediment into solid rock. As [...]

A swimming race illustrates the simple principles involved in measuring time. This swimmer is competing in a 1,500 metre race and we have an accurate, calibrated wristwatch. We note that at the instant the swimmer touches the edge of the pool our wristwatch reads 7:41 and 53 seconds. How long has the [...]
