  2. Relative dating - Wikipedia

    en.wikipedia.org/wiki/Relative_dating

    Relative dating by biostratigraphy is the preferred method in paleontology and is, in some respects, more accurate. [1] The Law of Superposition , which states that older layers will be deeper in a site than more recent layers, was the summary outcome of 'relative dating' as observed in geology from the 17th century to the early 20th century.

    Paleomagnetism (a relative dating method, see the corresponding list above) Marine isotope stages based on the oxygen isotope ratio cycle (a relative dating method, see the corresponding list above) Tephrochronology (an absolute dating method, see the corresponding list above)

  4. Absolute dating - Wikipedia

    en.wikipedia.org/wiki/Absolute_dating

    Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating , as use of the word "absolute" implies an unwarranted certainty of accuracy.

    en.wikipedia.org/wiki/Comparison_of_genealogy...

    Genealogy software products differ in the way they support data acquisition (e.g. drag and drop data entry for images, flexible data formats, free defined custom attributes for persons and connections between persons, rating of sources) and interaction (e.g. 3D-view, name filters, full text search and dynamic pan and zoom navigation), in reporting (e.g.: fan charts, automatic narratives ...

  6. Stratigraphy - Wikipedia

    en.wikipedia.org/wiki/Stratigraphy

    This timescale remained a relative scale until the development of radiometric dating, which was based on an absolute time framework, leading to the development of chronostratigraphy. One important development is the Vail curve , which attempts to define a global historical sea-level curve according to inferences from worldwide stratigraphic ...

  7. Robot calibration - Wikipedia

    en.wikipedia.org/wiki/Robot_calibration

    A calibrated robot has a higher absolute as well as relative positioning accuracy compared to an uncalibrated one; i.e., the real position of the robot end effector corresponds better to the position calculated from the mathematical model of the robot. Absolute positioning accuracy is particularly relevant in connection with robot ...

  9. Biochronology - Wikipedia

    en.wikipedia.org/wiki/Biochronology

    In terrestrial deposits, fossils of land mammals and other vertebrates are used as stratigraphic tools, but they have some disadvantages relative to marine fossils. They are seldom evenly distributed through a section, and they tend to occur in isolated pockets with few overlaps between biozones.
