While also using the international Geologictimescale , many nations especially those with isolated and therefore non standard prehistories use their own system of dividing geologictime into epochs and faunal stage s. In New Zealand , these epochs and stages use local place names mainly Maori language Maori in origin back to the Permian . Prior to this time, they largely use the same terms as used in the Australian geologictimescale , and are not divided into epochs. In practice, these early terms are rarely used, as most New Zealand geology is of more recent origin. In all cases, New Zealand uses the same periods as used internationally it is only the subdivisions of these periods that have been renamed. Very few epochs and stages cross international period boundaries. Of those that do, almost all are within the Cenozoic Era. Though the New Zealand geologictimescale has not been formally adopted, it has become widely used by New Zealand earth science earth scientists , geology geologists and palaeontology palaeontologists since its proposal by J.

refimprove date January 2008 In astrophysics , the thermal timescale is an estimate of the lifetime of a star once its fuel reserves at its center are used up or if they were to disappear. Along with the nuclear timescale nuclear and dynamical timescale s, it is used to estimate the length of time a particular star will remain in a certain phase of its life and its lifespan if hypothetical conditions are met. In reality, the lifespan of a star is greater than what is estimated by the thermal timescale because as one fuel becomes scarce, another will generally take its place hydrogen burning gives way to helium burning , which is replaced by carbon burning . Stellar astrophysics The size of a star as well as its energy output generally determine a star s thermal lifetime because the measurement is independent of the type of fuel normally found at its center. Indeed, the thermal timescale assumes that there is no fuel at all inside the star and simply predicts the length of time it would take for the resulting change in outputted energy to reach the surface of the star and become visually apparent to an outside observer. math tau th frac mbox total energy mbox rate of energy loss frac GM 2 RL math where G is the gravitational constant , M is the mass of the star, R is the radius of the star, and L is the star s luminosity In astronomy luminosity .

In astrophysics , the nuclear timescale is an estimate of the lifetime of a star based solely on its rate of fuel consumption. Along with the thermal timescale thermal and dynamical timescale s, it is used to estimate the length of time a particular star will remain in a certain phase of its life and its lifespan if hypothetical conditions are met. In reality, the lifespan of a star is greater than what is estimated by the nuclear timescale because as one fuel becomes scarce, another will generally take its place hydrogen burning gives way to helium burning, etc. However, all the phases after hydrogen burning combined typically add up to less than 10 of the duration of hydrogen burning. Stellar astrophysics Hydrogen generally determines a star s nuclear lifetime because it is used as the main source of fuel in a main sequence star. It constitutes much of the star s core and is surrounded by what is known as a helium shell. Hydrogen becomes helium in the nuclear reaction that takes place within stars when the hydrogen has been exhausted, the star moves on to another phase of its life and begins burning the helium. math tau nuc frac mbox total mass of fuel available mbox rate of fuel consumption times mbox fraction of star over which fuel is burned frac MX frac L Q times F math where M is the mass of the star, X is the fraction of the star by mass that is composed of the fuel, L is the star s luminosity In astronomy luminosity , Q is the energy released per mass of the fuel from nuclear fusion the chemical equation should be examined to get this value , and F is the fraction of the star where the fuel is burned F is generally equal to .1 or so .

Dynamical timescale has two distinct meanings and usages, both related to astronomy In one use, which occurs in stellar physics, the dynamical timescale is alternatively known as the freefall timescale , and is in general, the length of time over which changes in one part of a body can be communicated to the rest of that body. This is often related to the time taken for a system to move from one equilibrium state to another after a sudden change. In another use, in connection with time standards, dynamical time is the time like argument of a dynamical theory and a dynamical timescale in this sense is the realization of a time like argument based on a dynamical theory that is, the time and timescale are defined implicitly, inferred from the observed position of an astronomical object via a theory of its motion. A first application of this concept of dynamical time was the definition of the ephemeris timescale ET . ref B Guinot and P K Seidelmann 1988 , http adsabs.harvard.edu abs 1988A 26A...194..304G Time scales Their history, definition and interpretation , Astronomy and Astrophysics ...?id uJ4JhGJANb4C&pg PA41 at page 41 . ref Stellar physics For a star, the dynamical timescale is defined as the time that would be taken for a test particle released at the surface to fall under the star ... timescale measures the amount of time it would take a certain star to collapse in the absence ... velocity .

for temperature changes on other time scales Temperature record The Geologic temperature record are changes in Earth s Environment biophysical environment as determined from geology geologic evidence on multi million to billion 10 sup 9 sup year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a crucial component of the climate and oceanography of the time. Evidence for past temperatures Expand section date February 2008 see also paleoclimatology paleothermometer Our evidence for past temperatures comes mainly from isotopic considerations especially delta 18 O link the Mg Ca ratio of foramanifera foram tests, and alkenone s, are also useful. Often, many are used in conjunction to get a multi proxy estimate for the temperature. This has proved crucial in studies on glacial interglacial temperature. ref name sigmanboyle2000 cite journal title Glacial interglacial variations in atmospheric carbon dioxide journal Nature first D.M. last Sigman coauthors E.A.
