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. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history.
Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics. In historical geology , the primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young radiocarbon dating with 14 C to systems such as uranium—lead dating that allow acquisition of absolute ages for some of the oldest rocks on Earth.
Radiometric dating is based on the known and constant rate of decay of radioactive isotopes into their radiogenic daughter isotopes.

Geology can also include the study of the solid features of any terrestrial planet or natural satellite such as Mars or the Moon. Modern geology significantly overlaps all other earth sciences , including hydrology and the atmospheric sciences , and so is treated as one major aspect of integrated earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks.
Geology provides the primary evidence for plate tectonics , the evolutionary history of life , and the Earth’s past climates. Geologists use a wide variety of methods to understand the Earth’s structure and evolution, including field work , rock description , geophysical techniques , chemical analysis , physical experiments , and numerical modelling. In practical terms, geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources , understanding of natural hazards , the remediation of environmental problems, and providing insights into past climate change.
Geology is a major academic discipline , and it plays an important role in geotechnical engineering. The majority of geological data comes from research on solid Earth materials. These typically fall into one of two categories: rock and unlithified material. The majority of research in geology is associated with the study of rock, as rock provides the primary record of the majority of the geologic history of the Earth.
The Age of the Earth
Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks. It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates. It is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and it can be used to date a wide range of natural and man-made materials.
The best-known radiometric dating techniques include radiocarbon dating, potassium-argon dating, and uranium-lead dating. By establishing geological timescales, radiometric dating provides a significant source of information about the ages of fossils and rates of evolutionary change, and it is also used to date archaeological materials, including ancient artifacts. The different methods of radiometric dating are accurate over different timescales, and they are useful for different materials.

Chronological dating , or simply dating , is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a “dating method”. Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history , archaeology , geology , paleontology , astronomy and even forensic science , since in the latter it is sometimes necessary to investigate the moment in the past during which the death of a cadaver occurred.
Other markers can help place an artifact or event in a chronology, such as nearby writings and stratigraphic markers. Dating methods are most commonly classified following two criteria: relative dating and absolute dating. Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.
In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the most recent and the oldest possible moments when an event occurred or an artifact was left in a stratum , respectively. But this method is also useful in many other disciplines.

Fossils is an identification event which rotates with Rocks and Minerals every two years. Students identify various fossilized animals and plants, provide details about these organisms such as environment, mode of life, etc. There are several ways that fossils can form, ranging from the organism being replaced by minerals to the organism getting trapped in amber.
This section explains the different types of fossils. Fossils almost always form in sedimentary rocks. The extreme heat and pressure needed to form igneous or metamorphic rock often destroys or warps the organism. When an organism dies, if the conditions are right, it becomes covered in sediments, which, after being subjected to pressure, becomes rock. This takes a very long time, and the actual organism decomposes by then.
A soft organism like a worm or jellyfish usually does not get fossilized because it decomposes too fast.

There are many isotopes and minerals that can be used for radiometric dating and therefore many different ways to perform a thermochronology study. Toggle navigation. Search open E I. Other definitions: Wikipedia Reegle. The closure temperature is when the crystal structure of a mineral has formed and cooled sufficiently to prevent diffusion of isotopes. At this point the mineral begins to display measurable radioactive decay. For radiometric dating when the mineral reaches the closure temperature that is when the clock starts.
In other words, the age of the rock is calculated based on the point in time that it reached the closure temperature. Different minerals have different closure temperatures, so dating the different minerals within the same rock can give information about the thermal history of the rock i. This is known as thermochronometry. JPG thumb center px There are multiple techniques for capable of providing thermochronometry data in geothermal areas.
