Synroc, a portmanteau of "synthetic rock", is a means of safely storing radioactive waste. It was pioneered in 1978 by a team led by Professor Ted Ringwood at the Australian National University , with further research undertaken in collaboration with ANSTO at research laboratories in Lucas Heights .
Rock can also be modified with other substances to develop new forms, such as epoxy granite. [24] Artificial stone has also been developed, such as Coade stone. [25] Geologist James R. Underwood has proposed anthropic rock as a fourth class of rocks alongside igneous, sedimentary, and metamorphic. [26]
The classification method depends on the type and detail of research being conducted. [1] [2] [5] A sedimentary rock composed largely of gravel is first named according to the roundness of the gravel. If the gravel clasts that comprise it are largely well-rounded to subrounded, it is a conglomerate.
Anthropic rock is rock that is made, modified and moved by humans. Concrete is the most widely known example of this. [ 1 ] The new category has been proposed to recognise that human-made rocks are likely to last for long periods of Earth's future geological time , and will be important in humanity's long-term future.
The following is a list of rock types recognized by geologists.There is no agreed number of specific types of rock. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type.
Petrophysics (from the Greek πέτρα, petra, "rock" and φύσις, physis, "nature") is the study of physical and chemical rock properties and their interactions with fluids. [1] A major application of petrophysics is in studying reservoirs for the hydrocarbon industry.
Geothermobarometry relies upon understanding the temperature and pressure of the formation of minerals within rocks. [1] There are several methods of measuring the temperature or pressure of mineral formation or re-equilibration relying for example on chemical equilibrium between minerals [1] [2] [3] or by measuring the chemical composition [4] [5] and/or the crystal-chemical state of order [6 ...
Research is proceeding to evaluate the practicality of sequestering the greenhouse gas carbon dioxide in magnesite on a large scale. [26] This has focused on peridotites from ophiolites (obducted mantle rocks on crust) where magnesite can be created by letting carbon dioxide react with these rocks.
