ESR dating for the early Earth

ESR dating of barite in sea-floor hydrothermal deposits, a new dating technique

EVIDENCE FOR AN ANCIENT EARTH Radiometric Dating - A Christian Perspective

Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements-has been in widespread use for over half a century. There are over forty such techniques, each using a different radioactive element or a different way of measuring them. It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, prese...

A portable system of X-ray irradiation and heating for electron spin resonance (ESR) dating

In this study we present details of a portable system which contains an X-ray source and heater, designed to irradiate and heat samples within a quartz glass tube for electron spin resonance (ESR) dating. The spatial distribution of the X-ray beam was measured with a radiation sensitive film and the images were scanned and mapped using the Risoescan software. The reproducibility of irradiations...

Electron Spin Resonance (ESR) Dating of Calcareous Fault Gouge of the Ushikubi Fault, Central Japan

The ages of fault events of active faults have been estimated using electron spin resonance (ESR) signals of siliceous gouges. This technique of ESR method is limited by obtaining only ages that are greater than tens of millennia. So this study focuses on developing a new technique of using calcareous gouges to gain an insight into the ages of latest seismogenic event within the Holocene. For t...
