Dear colleagues
Which minerals have melting point less than 30 degree celsius exposed on outcrop?
regards
Ijaz
Well,
Gallium Ga and Caesium Cs.
Regards
Please do not forget the mineral species native mercury.
The melting point of the mineral species native mercury is
−38,8344 degrees Celsius ( 0.10 MPa => pressure condition on sea level).
Best regards,
Guenter Grundmann
Mirabilite melting is close to this temperature (32.4 C)
The following 5: Bromine, mercury, caesium, rubidium, gallium (and rare francium)
And do not forget native/ elemental fluorine which was identified in fetid fluorite (CaF2) as a result of radiation damage in samples from the Wölsendorf mining district, Germany, by chemists from München Technical University
melting point : -219.6 °C
H.G.Dill
Meridianiite, ikaite, hydrohalite. However, they do not melt, but decompose inconguerently.
i am unable to interpret why its increases in start as shown in figure
