Chance finds of several distinctive Mesolithic flint tools and working debris, together with shell middens and occasional structural remains, indicate that Islay was occupied from at least as early as 8000 BC.
This 5-12-grade activity introduces students to the idea of sequencing information in overlapping data sets and the Principle of Superposition, which is a core concept in relative dating. Offers history of age dating, stratigraphic principles, rock correlation, fossil correlations, radiometric dating, and the geologic time scale. Short discussion of radioactive dating and stratigraphic principles.
Radiometric Dating and the Geologic Time Scale, The Talk Origins Archive. Provides brief overview of (1) relative dating and stratigraphic methods, (2) absolute dating and radiometric dating, including a table with parent to daughter isotopes and half lives of those isotopes commonly used in radiometric dating, (3) paleomagnetics and (4) geologic time. Includes tables of common radioactive parent isotopes and their stable daughter products, and half lives of common radioactive isotopes.
The only known broch site on the island is located at Dun Bhoraraic near Ballygrant.
While there are numerous fortified dun sites throughout the island and especially on the coast edge, the period of their construction and use is little known, although it is probable that a proportion are of Iron Age date.
