Ice Ages
Greg Neyman
(Investigator 111, 2006 November)
For many years the young earth creation science community has argued
that the one single ice age occurred as a result of the aftermath of
Noah's Flood.
While it is obvious that the recent Ice Age deposited sediments that
are on top of all the ancient rock layers, what is not so obvious is
the periods of glaciation which occurred in the geologic past.1
They have made an attempt to explain these away. Michael Oard (a
meteorologist) has an article on the young earth creation science
website Answers In Genesis,
claiming that these ancient deposits are submarine debris flows.
He is right in that one geologist thinks the Bigganjargga is a debris
flow. However, it's poor science for a meteorologist to assume
that this can translate to ALL ancient glacial deposits. He does not
address the others. If he had evidences against the rest, he would
definitely write about them. Instead, he has only weak evidence,
which can plainly be interpreted by a geologist as being glacial or
non-glacial.
This lack of evidence speaks volumes to the weakness of his conclusions.
Definitions
Glacial features are easy to spot in the geologic record because of
these easily-identified features:
Drift – general term referring to glacially-deposited sediment
Till – unsorted and unstratified glacial drift; usually contains both
local rock material, and rock material transported from a distant
source. Typical glacial till is unsorted, unstratified, has a variety
of particle sizes, and a wide range of particle lithology
Outwash – Till deposited from a melting glacier onto a continental mass
Glaciolacustrine – Deposits in a lake formed at the end of a melting
glacier
Glaciomarine – Deposits from a glacier contacting a marine boundary
Tillite – Lithified version of glacial till
Clasts – Rock composed of fragmented material
Glacial Striation – linear excavations (generally small) that are
formed by the sediment-laden ice as it passes over bedrock. The
larger grooves may be several meters deep in soft rocks.
Crescentic Gouges – Gouge cut into bedrock by an ice sheet, in the form
of a crescent, usually several centimeters in length
Ice Rafting – Large pebbles dropped by melting ice. They are dropped
into a soft-mud surface as the ice melts
Late Paleozoic Glaciation
Widespread, well-known glacial deposits occur throughout the Southern
Hemisphere Gondwanaland landmasses, ranging from Carboniferous to
Permian in Age (354 to 248 million years ago).
Dwyka Formation
These glacial deposits occur throughout southern Africa. The Dwyka is
about 1300 meters of sediment, with the middle 800+ containing tillite
units. These units rest on widespread striated pavements, and contain
striated and faceted clasts. Well-preserved glacial valleys are exposed
throughout the area. The tills are typical, including clasts
orientations, and contain both local and remotely-derived gravel
particles.
Permian of Australia
Glaciers were widespread over all of Australia during the Late
Carboniferous, with continental ice sheets reaching maximum coverage
during Permian time. The evidences for this ice exists throughout the
entire spectrum of glacial sediments, which includes outwash,
glaciolacustrine, and glacial marine deposits. Glacial pavements with
striations, grooves, and crescentic gouges abound.
At Hallet Cove and Fleurieu Peninsula there are clasts of various
plutonic and metamorphic sources. Ice rafting was also common, as
evidenced by the large dropstones scattered throughout.
It is estimated that there were dozens of glacial advances in
southeastern Australia during the Permian.
Why Does It Matter?
The above two examples of Carboniferous/Permian glaciation occurs in
rocks that are 248 to 354 million years old. According to the
young earth Flood model, deposits put down during this time are
considered as being deposited during the early part of Noah’s Flood.2
How could there be widespread glaciers at a time when the entire globe
was underwater?
The young-earth model cannot give any explanation for the existence of
these glacial deposits and features. Because these rocks are Permian in
age the Flood could not possibly have deposited them. As such,
this is enough evidence to disprove the global flood model proposed by
young earth creation science experts.
Even More Evidence!
Tillites are well-documented on all continents except Antarctica, with
dating to the Precambrian, 650 to 700 million years ago. By the
young-earth model, these glacial deposits are considered as creation
week rocks, however it seems odd that during the intense mountain
building, volcanic-ridden creation week, glaciers dominated six of the
seven continents!
The Varangian Ice Age deposits are found throughout northern Europe,
the British Isles, and Greenland. Pebbly mudstones (from ice
rafting) are common, with some striated pavements. The Port Askaig
Tillite in Scotland and Ireland is over 700 meters thick, and contains
glacial marine, glacial fluvial, and nonglacial sediments. In
Norway, the Upper and Lower Tillite Formations contains tillites
deposited in a glacial marine environment.
In Canada, the Gowganda Formation, also Precambrian, displays typical
glacial till features; poor sorting, unstratified, varying particle
sizes and sources. Sandstone lenses show evidence of ice
rafting. The base of the formation contains striations and
grooves in the underlying bedrock. The age of this formation is
considerably older, at 1,300 million years old.
Conclusion
The existence of glacial deposits in early Noah's Flood rocks shows
that the young-earth model for the Flood is inadequate. There could not
have been glacier deposition when the entire world was under water. Nor
could there be glacial deposition during the rapid mountain building of
the creation week. Clearly the young earth creation science model is
flawed. But the old earth model, with God creating the earth over the
last 4.5 billion years, fits perfectly with the evidence of the rock
record.

THE "SCIENCE" OF CREATION REQUESTED
John H Williams
(Investigator 112, 2007 January)
Regarding the contributions of our new writer, Greg Neyman:
As a geologist I find no fault in his work, such as his thoroughly
researched piece on Ice Ages in # 111 (to which I referred in pages
38/39 of #107). He and I have made our point and now await debunking
from Young Earthers but it will likely not occur.
Yet, above his Ice Ages title are the words "Creation Science Exposed",
as if the author were a non-creationist, when he's made it clear that
he's an Old Earth creationist:
"Clearly the young
earth creation science is flawed. But the old earth
model, with God creating the earth over the last 4.5 billion years,
fits perfectly with the evidence of the rock record." (G Neyman Page
42, #111)
Greg also mentions the Great Flood as if he might believe in Genesis,
Noah and Her-in-Ark, their three sons and three unnamed wives, the
progenitors of all humans. Could he please specify what he does
believe, and why he believes it, rather than spend most of his energies
in debunking 'the other lot'?
Greg's entitled to his religious beliefs, but isn't it reasonable that
he, as a geologist, sets out his scientific views on 'creation'? He'd
be aware that I and a number of
Investigator readers are scientists, or
have respect for the work of science, and are highly sceptical of
'creation science' of whatever age.
