چکیده
How to tell time: • Relative Time: putting events in time order. • Law of Superposition • Correlation of rock layers using fossils. William Smith " There is a wonderful order and regularity with which nature has disposed of fossils and assigned to each its peculiar stratum. " How to tell time: • Absolute Time: Determining age in years.

Optical dating of Holocene lake bed sediments of the Nimbluk Plain, Khorasan, Northeast Iran: Implications for the climate change and palaeo-environment
We have investigated an optically stimulated luminescence (OSL) dating study in the Nimbluk lakebed in Khorasan, northeast Iran. Two samples of the lake-bed sediments from ~1 m below the land surface are successfully dated at 7.3-9.9 ka. All necessary experiments have been performed to choose the most suitable procedure for dating quartz extracts using single aliquot regeneration method (SAR). ...

The study area is located in northeastern Iran (south of Mashhad). Paleo-Tethys Ocean opened during Silurian time and subduction under Turan plate was started in Late Devonian. By Late Triassic (225 Ma) there was no Paleo-Tethys left on an Iranian transect, therefore Turan plate obducted over Iran Plate. Two stages of low grade regional metamorphism are exposed, that are related to Hercynian (L...
متن کاملEVIDENCE FOR AN ANCIENT EARTH Radiometric Dating - A Christian Perspective
Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements-has been in widespread use for over half a century. There are over forty such techniques, each using a different radioactive element or a different way of measuring them. It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, prese...
متن کاملThe Age of the Earth
The oldest rocks which have been found so far (on the Earth) date to about 3.8 to 3.9 billion years ago (by several radiometric dating methods). Some of these rocks are sedimentary, and include minerals which are themselves as old as 4.1 to 4.2 billion years. Rocks of this age are relatively rare, however rocks that are at least 3.5 billion years in age have been found on North America, Greenla...

The study area (Bornaward granite) is located in northeast of Iran (Khorasan Razavi province), about 280 km southwest of Mashhad city. Taknar zone is an exotic block, bordered by two major faults, Great Kavir fault (Drouneh) to the south and Rivash fault in the north. A complex of granite, granodiorite, monzonite and diorite crop out at the center of Taknar zone. They are named as “Bornaward gr...
