As organisms exist at the same time period throughout the world, their presence or sometimes absence may be used to provide a relative age of the formations in which they are found. The study of earth history by correlating archaeological events to the timing and sequencing of geological events. This has allowed the questioning of one of the underlying assumptions of radiocarbon dating , the constancy of the concentration of C14 in the atmosphere. For example, the oldest human remains known to date in Canada, found at Gore Creek , have been dated using soil stratification. An absolute chronometric dating technique for measuring time intervals and dating events and environmental changes by reading and dating the pattern number and condition of annual rings formed in the trunks of trees. A major application of dendrochronology in archaeology, as a tool for establishing dates from the samples of wood and articles made out of wood is not only in working out primary chronologies but also in cross checking the already known dates by other methods. The style of the artefact and its archaeology location stratigraphically are required to arrive at a relative date. This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years. Using microscopic observations and a range of chemical microanalysis techniques geochemists and igneous petrologists can obtain a range of useful information from melt inclusions. Sorby was the first to document microscopic melt inclusions in crystals.
