Carbon dating calibration


The "Lake Suigetsu 2006 Varved Sediment Core" project, or "Suigetsu Varves 2006" for short, is a multi-national, collaborative research project based around a sediment core taken from Lake Suigetsu [soo-ee-get-soo], central Japan, in summer 2006.

The two over-arching aims of the project are: The project will therefore contribute to international scientific endeavour by using multi-proxy palaeoenvironmental data to determine the precise timings and rates of environmental changes, and in facilitating understanding of past changes in the global carbon cycle.

The science of geology is founded on basic principles that are useful for making observations about the world around us.

This chapter presents a mix of information that is essential (fundamental) to all following chapters.

Here is one example of an isochron, based on measurements of basaltic meteorites (in this case the resulting date is 4.4 billion years) [Basaltic1981, pg. Skeptics of old-earth geology make great hay of these examples.

In addition, basic geologic principles can be applied to resolving the order of events leading to the formation of rocks and landscape features. Cross Sections - interpretations of vertical views of geologic features below the surface.

The excess energy associated with this excited state is released when the nucleus emits a photon in the -ray portion of the electromagnetic spectrum.

Most of the time, the -ray is emitted within 10Nuclides with atomic numbers of 90 or more undergo a form of radioactive decay known as spontaneous fission in which the parent nucleus splits into a pair of smaller nuclei.

Alpha decay is usually restricted to the heavier elements in the periodic table.

(Only a handful of nuclides with atomic numbers less than 83 emit an -particle.) The product of -decay is easy to predict if we assume that both mass and charge are conserved in nuclear reactions.

The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.
