  1. decrepitationnoun

    the crackling or breaking up of certain crystals when they are heated


  1. decrepitationnoun

    The shattering of minerals by the action of heat, especially when accompanied by a crackling sound

Samuel Johnson's Dictionary

  1. Decrepitationnoun

    The crackling noise which salt makes, when put over the fire in a crucible. John Quincy

    Etymology: from decrepitate.


  1. decrepitation

    Decrepitation is the process or act of cracking, breaking, or bursting apart upon being exposed to extreme heat. This term is often used in mineralogy to describe the sound or cracking effect produced by certain minerals when rapidly heated. It can also refer to the noise that certain salts make when heated, due to the rapid disintegration or expansion.

Webster Dictionary

  1. Decrepitationnoun

    the act of decrepitating; a crackling noise, such as salt makes when roasting

  2. Etymology: [Cf. F. dcrpitation.]


  1. Decrepitation

    Decrepitation is the act of heating up a calcine, also known as a salt, to the point that it crackles or continuously until the crackling stops. Decrepitation is one of the most accurate ways to calculate a mineral-deposit scale so that the analysis of the hydrothermal system is advanced and improved. Fluid inclusions are important in regards to decrepitation because they are the microscopic areas of gas and liquid within crystals that are decrepitated, or broken, with the application of heat. From decrepitating the crystal or salt the liquid pressure is released which can result in a crack. However, a problem arises because in some cases the fluid inclusions are not fully decrepitated, in which case other methods must be used. Despite this shortcoming, decrepitation is the preferred procedure for identifying minerals because it allows for the quickest and greatest number of inclusions to be measured. It was found that the pressure necessary to spur decrepitation is reliant upon the size of the fluid inclusions; bigger inclusions decrepitate more easily at pressures between 700-900 atmospheres, while smaller fluid inclusions may require upwards of 1200 atmospheres, contrastingly, when fluid inclusions become even smaller, the amount of pressure applied will have no effect and decrepitation will not occur. To further explain the process of decrepitation it is necessary to look at the heat required to decrepitate certain minerals. If the decrepitation begins at a temperature less than the temperature required to form the mineral, it is likely that the rate of decrepitation will speed up once the temperature exceeds that of the initial heating. Because of this commonplace of decrepitation it is exorbitant to extract different minerals from metamorphic rocks because the metamorphic rock was formed at a certain temperature and therefor the decrepitation of the various minerals will all be around the same temperature. For metamorphic rocks there are certain principles for measuring the decrepitations. What is known as D1 decrepitation, is classified as a temperature range of about 200-300℃ which is not especially intense, and is caused by the liquid phase which occupies intricate inclusions, as in hydrothermal minerals. D2 decrepitation is characterized by a starting heat range of about 300-700℃, the temperature can also increase rapidly for a few hundred degrees, such as in solid inclusions. D3 decrepitation is continuously heated until the rate maxes out at about 350-450℃, D3 decrepitation can be observed in carbonates. One explanation of the rate peaking at this temperature is the fact that it corresponds to the crucial temperature of water and calcine solutions; a deduction can be made that water is contained within parts of the mineral. D4 decrepitation is defined by the affect of an inversion of the mineral. Once decrepitation of a D4 mineral is reached it should reach completion within a few degrees, which is seen in the decrepitation of quartz. Decrepitation as a result of decomposition is known as D5 decrepitation, it is characterized by a sharp upwards rate, a definite peak, and a sharp downwards rate, this can be detected by comparing the peaks of various minerals within a rock.
