Measurement of the ratio of these isotopes thus gives the age of the minerala technique for determining the age of organic materials, such as wood, based on their content of the radioisotope 14C acquired from the atmosphere when they formed part of a living plant.
All that we think we know is wrong, with tidbits of truth interwoven to enhance the narrative.
After alternating field demagnetization in 200 Oe the palaeomagnetic inclination log shows the Brunhes/Matuyama boundary at 110 m below which the Jaramillo and Olduvai Events within the Matuyama Epoch are identified.
This interpretation of the magnetostratigraphy is supported by palaeontological evidence.
Many scientific facts from the past are no longer facts. The Earth Sciences are the Swiss cheese of science, having so many anomalous holes in their theories that it’s hard to know where to begin.
I was told apologetically by a scientist, that with all its faults “science is doing its best”, while at the same time we have the sceptics telling us that science is a kind of ideal or in some extreme cases an absolute, a cornucopia of all knowledge. Contrary to popular belief nothing is known about what lies more than a mile or two beneath our feet as will be seen, and yet the geologists claim to know about the structure of the Earth all the way down to its core, disregarding the fact that seismic reflection surveys could not be more wrong, as we will soon see.
