Dating in archaeology is the process of assigning a chronological value to an event in the past. Application of TCNs to archaeological problems is relatively simple: either surface exposure dating (using cosmogenic nuclide pro-duction) or burial dating . Journal of Geographical Sciences.
Surface exposure dating is a collection of geochronological techniques for estimating the length of time that a rock has been exposed at or near Earth's surface. Application of TCNs to archaeological problems is relatively simple: either surface exposure dating (using cosmogenic nuclide production) or burial dating. Just as TCNs are applicable to a broader time period with considerable precision in archaeology, so also are they applicable to all lithologies.
Weathering and erosion encapsulate a diverse suite of processes that sculpt landscapes, generate soil, and deliver sediments, nutrients, and solutes to streams and the oceans. Quantifying chemical and physical erosion rates is important across a diverse range of disciplines in geology, geomorphology, and biogeochemistry. Yet, until recently, erosion rates have been difficult to quantify over the timescales of soil formation and transport. This article describes how cosmogenic nuclide methods have provided a wealth of new opportunities for dating surfaces, measuring denudation rates, and quantifying chemical erosion rates.
TCN techniques rely on the ingrowth of nuclides within the mineral lattice hence, in situ TCNs as a result of the interactions between secondary cosmic radiation and minerals in that lattice, and the Ar-Ar technique is a development of the technique that relies on the decay of K to Ar to date volcanic rocks and weathering products. Dating sediment burial over million-year time scales is crucial in many areas of the Earth sciences and archeology, but is often difficult using traditional.
