Dating in exposed and surface contexts
Some problems with ‘direct dating’ of rock-pictures. Crisis in traditional ideas about European rock art: the question of diffusion and convergence. Use of rock weathering rinds in dating geomorphic surfaces / Peter L. Knuepfer -- The Schmidt hammer as a measure of degree of rock surface weathering and terrain age / Danny Mc Carroll -- Dating surface assemblages using obsidian hydration / Charlotte Beck and George T.Jones -- Surface exposure dating with rock varnish / Ronald I.
If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.Low energy fluvial sediment, like shallow channel fills with millimeter-scale, horizontally-bedded, medium sands is the preferred facies for OSL dating (Schaetzl and Forman, 2008).Higher energy facies with erosion of previous deposited sediments and formation of new grains with clast percussion during saltation and creep at the base of the water column often yield a mixture of apparent grain ages.There are a number of sedimentary facies that have the potential to be dated by luminescence.A luminescence age for clastic sediment is a measure of the time since the last sunlight exposure.
