The Geomagnetic Field Problem
The mechanism for generating the
geomagnetic field remains one of the
central unsolved problems in
geoscience.

Z Space - Excess Mass Stress Tectonics EMST - and Magnetism
In Z Space and EMST, Magnetism is
Concentration of Space and Electricity
is Rarefaction of Space and they both
form an Electromagnetic Wave in

Generated Stripe Pattern of Magnetic Anomalies
Maxlow, 2001
In conventional plate tectonics and Earth expansion literature the lithosphere
is produced in mid-ocean ridges, and magnetic anomalies form stripes
parallel to them. But, the oceanic magnetic anomaly surface traces are the
result of the measurement “moving average filter" applied to a random and a
finer variation not in one-to-one correspondence with a historical sequence
of geomagnetic reversals. Thus the intensity traces/stripes, (thought to be a
few tens of kilometres wide), are traces produced by the measurement
process acting upon randomly generated intensity variation of primarily
finer grain, and the correlations observed between widely separated observed
traces are impressively better than are the correlations between randomly
generated and averaged traces (Smith & Smith, 1993).
Observed Spot Pattern of Magnetic Anomalies
The random-spot pattern of crustal magnetic anomalies caused by regional
variations in the bulk magnetic properties of the Earth's crust. NASA’s Earthorbiting satellite, Magsat, made the observations from late 1979 to mid 1980 at
approximately 400 km altitude. Warm colors (reds) indicate the strongest
magnetizations while cool colors (blues) the weakest (Purucker et al., 1997). The
strongest anomalies-few nT, are observed in continental areas, and the ratio of
crustal anomalies to main magnetic ‘field’ is in the range of 10-4, similar to the ratio
of gravity anomalies to the Earth’s gravity ‘field’.
The Moving Average Filter
Consecutive waveform data points are represented by "y“, and a smoothing
factor, e.g., of 3 was applied, which means 3 consecutive data points from the
original waveform are added, their sum divided by 3, and then this quotient is
plotted as the first data point of a generated waveform and so on, until the end of
the data is reached. This special "feathering" technique averages the beginning
and end data points of the original wave-form to ensure that the generated
waveform contains the same number of data points as the original. Note the
overlap that exists in the moving average calculations, and the reason for
applying a moving average filter is to "smooth out" the high and low
aberrations and reveal a more representative intermediate waveform value.

The Stripe Pattern Artifact
The intensity measurements are made from surface vessels which travel
several kilometres above the ocean floor, and the basement rock. The intensity
measured at any surface point is thus actually the (weighted) average effect
of the intensities in the basement rock for a horizontal distance of several
times the vertical distance to the measuring device. Thus the observed oceanic
magnetic anomaly surface traces are the result of the measurement "filter"
applied to a random and a finer variation not in one-to-one correspondence
with a historical sequence of geomagnetic reversals. The intensity
traces/stripes, (thought to be a few tens of kilometres wide), are traces
produced by the measurement process acting upon randomly generated
intensity variation of primarily finer grain, and the correlations observed
between widely separated observed traces are impressively better than are the
correlations between randomly generated and averaged traces (Smith & Smith,
1993).
Deep Sea Drilling Project
The confirmation of the generated stripe pattern of Mesozoic and Cenozoic
magnetic anomalies could come from a direct examination of the magnetic
orientation of the oceanic basement rock beneath the sedimentary layers.
But, such information is not currently available. The Deep Sea Drilling Project
has drilled the ocean floor in 624 sites but generally these holes are confined to
the sedimentary layers (see Hall and Robinson 1979, Hall and Ryall 1977, Smith
1985, and Smith and Banerjee 1986). Only 3 or 4 holes have penetrated the
basement to any great degree. These few holes have shown a wide scatter of
magnetic inclinations within each hole and have not demonstrated lateral
continuity (Smith & Smith, 1993).
Crustal Fragmentation and Excess Mass

Maxlow, 2001
The lithoshpere is not created in midocean ridges, and therefore Earth
expansion cannot be attributed to
this process. The primary mechanism
for crustal extension and accretion
during Earth expansion, starts with
crustal stretching (a), is continued with
crustal rifting (b), and ends with
crustal
fragmentation
and
the
emplacement of Excess Mass (c). In
each figure continental crust is shown as
green, mantle as pink shading, and
intracratonic basin sedimentation shown
as horizontal stripes.
Regarding age dating of the sea floor
sediments they don't use the sediments,
they use the microfossils deposited on
the sea floor as they die and rain down
on the sediments. They also use the
volcanic basement rocks that the
sediments sit on as an added method.
Oceanic Plateaus
Ben-Avraham et al., 1981; Storetvedt, 1997.
Some of the oceanic plateaus, for example the Kerguelen-Gaussberg and
Ontong-Java Plateau are intermediate continental-oceanic crust formations; the
Chatham and the Galapagos Rise are continental crust formations, thus giving
merit to the crustal fragmentation and emplacement of excess mass
erratically between them.
Conclusion
Therefore,
the Stripe Pattern of Magnetic Anomalies is
an Experimental Artifact.
