QUARTZ is present mainly as the species H_4SiO_4 in fluid. The currently accepted values for quartz solubility at low temperatures are low. At 300℃, quartz solubility is about 600×10~(-6) in the quartz-fluid system. Therefore, the migration of quartz should not be evident at low temperatures. However, thepresent note shows that quartz can be enriched and migrate significantly at 300℃. The solid/fluid ratio(S/F) of the experiments is only about 10 g/mL.
The currently accepted values for quartz solubility at low temperatures are low. At 300 ° C, the quartz solubility is about 600 × 10 -6 (-6) in the quartz-fluid system. Thus, the However, thepresent note shows that quartz can be enriched and migrate significantly at 300 ° C. The solid / fluid ratio (S / F) of the experiments is only about 10 g / mL.
