THMKS-600 Geological Fluid Inclusion Cold and Hot Table

THMKS-600typeGeological fluid inclusionsCold and hot table

It is an ancient fluid (which can be an aqueous solutionCO₂Petroleum, melt, etc. They are equivalent to sealed ancient fluid sample bottles, preserving the physical and chemical information of the ore-forming fluids at that time.

2. uniform temperature(Homogenization Temperature, Th)：

During the heating process, the usually immiscible gas and liquid phases (such as water and bubbles) inside the package will become miscible and become a homogeneous phase (completely liquid or completely gas). The critical temperature at which this transition occurs is the uniform temperature.

Geological significance:ThRepresents the temperature at which the package was captured. If the capture is in a homogeneous phase, thenThIt is the real capture of temperature. This is a key parameter for restoring paleotemperature.

3. freezing temperature(Freezing Point Temperature, Tm)：

During the cooling process, the saline solution inside the package will freeze. Freezing point temperature（Tm）It refers to the temperature at which the last ice crystal melts and disappears.

Geological significance:TmSalinity of fluids(Salinity)There is a direct functional relationship. passTmCan accurately calculate the salinity of fluids (usually usingwt% NaCl equiv.To express).

2、 Application of Optical Cooling and Heating Platform

Optical cooling table（Microthermometry System）It is the core equipment for implementing the above measurements. It is essentially a precise temperature controlled chamber with optical windows, installed on the microscope stage, which can accurately heat and cool the package and observe the phase transition process in real time.

The main components of the hot and cold table are:

1. Host console: Equipped with precision thermocouples for cooling inside/Heating element, gas circulation system (usually using liquid nitrogen or compressed air refrigeration, resistance wire heating).

2. Sample chamber: a sealed small chamber in which samples are placed and filled with dry gas (such asN₂）To prevent frost from forming on the window.

3. Temperature control system: high-precision temperature program and reading device, modern equipment can accurately control the temperature change rate (such as0.1°C/min）The temperature measurement accuracy can reach±0.1°C.

4. Microscope: equipped with a long working distance objective lens for observing samples placed in cold and hot stage chambers.
