Temperature measured with Microthermometry:
Examples:
Melting of Ice
where L = liquid, V = vapour, m = melting
abbreviated:
Tm(Ice)
Homogenization
where L = liquid, V = vapour, h = homogenization
abbreviated:
Th(total)
note: both "homogenization" and "melting" can be used
Composition:
Volume Fraction:
where L = liquid, h = homogenization
abbreviated:
Tm(Halite)

note: parameter always in "italics", subscript always in "upright"
where mH2O is the mass of 55.51 mole H2O (= 1 kg)
Examples:
In a binary mixture of NaCl and H2O
xNaCl = 0.1
bNaCl = 6.1677
wNaCl = 26.5%
this corresponds to:
xNa+ = 0.0909
xCl- = 0.0909
xH2O = 0.8182
bNa+ = 6.1669
bCl- = 6.1669
wNa+ = 12.42%
wCl- = 17.94%
note: dissolved NaCl is dissociated in Na+ and Cl- ions
the system now includes three components (ternary): H2O , Na+ and Cl-
or
or
conformable to SI
Example:
where Vm is the molar volume, i is a phase (not a component!)

Volume:
Molar Volume (cm3/mol)
Density (g/cm3)
note: in many drawing software, "symbols" (or "greek") cannot be put in italics, use a horizontal skew angle.
the volume fraction of the vapour phase is 30% (or 0.3)
Bulk molar volume of fluid inclusion:
Bulk density of fluid inclusion:
In two phase fluid inclusions (LV):
Pressure:
The symbol for pressure is Pa (Pascal), or MPa, GPa. 1 Pa = 1 N/m2
The symbol for temperature is K (Kelvin), the use of degree Celsius is also allowed.
Do not use: bar (bar), standard atmosphere (atm), torr (torr), pound-force per square inch (psi)
Do not use: degree Fahrenheit, degree Rankine
