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.
When decrepitating the crystal or salt, the liquid pressure is released which can result in a crack.
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.
What is known as D1 decrepitation, is classified as a temperature range of about 200-300°C 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°C, the temperature can also increase rapidly for a few hundred degrees, such as in solid inclusions.
