Thermoluminescence dating of brazilian indigenous ceramics

There are dendrochronological records for Europe and the Aegean, and the International Tree Ring Database has contributions from 21 different countries.The main drawback to dendrochronology is its reliance on the existence of relatively long-lived vegetation with annual growth rings.

Without those, the archaeologists were in the dark as to the age of various societies. The use of tree ring data to determine chronological dates, dendrochronology, was first developed in the American southwest by astronomer Andrew Ellicott Douglass.In 1901, Douglass began investigating tree ring growth as an indicator of solar cycles.Douglass believed that solar flares affected climate, and hence the amount of growth a tree might gain in a given year.Plotting several curves can allow the archaeologist to develop a relative chronology for an entire site or group of sites.For detailed information about how seriation works, see Seriation: A Step by Step Description.
