Raman peaks of vari.us hydrates i. the H20-NaCl-CaCl2 system have been previ.usly i.enti.i.d, but a quanti.ati.e relati.nshi. between the Raman peaks and XNaCl （i.e.,NaCl/ （NaCl＋CaCl2）） has not been establi.hed, mai.ly due to the di.fi.ulty to freeze the soluti.ns. Thi. problem was solved by addi.g alumi.a powder to the soluti.ns to faci.i.ate nucleati.n of crystals. Cryogeni. （-185℃） Raman spectroscopi. studi.s of alumi.a-spi.ed soluti.ns i.di.ate that XNaCl i. li.early correlated wi.h the total peak area fracti.n of hydrohali.e. Capsules of soluti.ns made from si.i.a capi.lary were prepared to si.ulate flui. i.clusi.ns. Most of these arti.i.i.l flui. i.clusi.ns could not be totally frozen even at temperatures as low as -185℃, and the total peak area fracti.n of hydrohali.e i. not correlated li.early wi.h XNaCi. However, the degree of devi.ti.n （△XNaCl） from the li.ear correlati.n establi.hed earli.r i. related to the amount of resi.ual soluti.n, whi.h i. reflected by the rati. （r） of the baseli.e ＂bump＂ area, resulti.g from the i.tersti.i.l unfrozen bri.e near 3435 cm^-1, and the total hydrate peak area between 3350 and 3600 cm^-1. A li.ear correlati.n between △XNaCl and r i. establi.hed to esti.ate XNaCl from cryogeni. Raman spectroscopi. analysi. for flui. i.clusi.ns.

The densi.i.s of CO2 i.clusi.ns i. mi.erals are commonly used to determi.e the crystalli.i.g condi.i.ns of the host mi.erals. However, conventi.nal mi.rothermometry i. di.fi.ult to apply for i.clusi.ns of small si.e （〈 5-10 μm） or low densi.y. Raman analysi. i. an alternati.e method for determi.i.g CO2 densi.y, provi.ed that the CO2 densi.y-Raman shi.t relati.n i. known. Thi. study ai.s to establi.h thi. CO2 densi.y-Raman shi.t relati.n by usi.g CO2 i.clusi.ns synthesi.ed i. fused si.i.a capi.lari.s. By usi.g thi. newly-developed syntheti. techni.ue, we formed pure CO2 i.clusi.ns, and thei. densi.i.s were determi.ed by mi.rothermometry. The Raman analysi. showed that the relati.n between CO2 densi.y （D i. g/cm^3） and the separati.ns （△ i. cm^-1） between the two mai. bands （i.e. Fermi.di.d bands） i. CO2 Raman spectra can be represented by a cubi. equati.n： D （g/cm^3）=0.74203（-0.019^3＋5.90332△^2-610.79472△＋21050.30165）-3.54278 （r^2=0.99920）. Our calculated D value for a gi.en A i. between those obtai.ed from two previ.usly-reported equati.ns, whi.h were deri.ed from di.ferent experi.ental methods. An example was gi.en i. thi. study to demonstrate that the densi.i.s of natural CO2 i.clusi.ns that could not be deri.ed from mi.rothermometry could be determi.ed by usi.g our method.
