A supplement to metamorphism is metasomatism: the introduction and expulsion of fluids and elements through rocks during recrystallization.
The timing of cycles involving the expulsion of fluids from deep within the crust can be ascertained by dating new minerals formed at high pressures in exposed deep crustal sections.
We envisage that substantial volume of fluids were transferred from mantle into the lower crust through the younger plume-related Deccan volcanism, as well as the reactivation, fracturing and expulsion of fluids transported to depth during the Mesoproterozoic subduction tectonics.
Thought about abstractly, at a level of analytical remove, human sexual intercourse is an incredibly visceral thing; a series of genital insertions and digital entanglement that ends in the expulsion of fluids.
These processes include increasing the concentration of collagen in acid solution and/or the physical expulsion of excess fluid by means of compression.
When considered with analyses from previous decades, the results provide no evidence to associate the ten-year period of caldera deflation that began in 1985 with expulsion of magmatic fluids through the caldera rim in this area.
Furthermore, small tidal volumes, associated with lower peak expiratory flows, tend to limit proximal expulsion of biological fluids.
To cope with this high-salt diet, the marine iguana uses large cranial salt glands that excrete most of the sodium, potassium, and chloride ingested; forceful expulsion of the secreted fluid is the cause of the dramatic snorting and sneezing observed in these animals.
In some cases, it is possible to prove that gold deposits may have come from specific fluids if the deposition time of the deposits can be determined and the time of fluid expulsion is known.
Although compression of blended gels resulted in some cell death due to increased rate of fluid expulsion, not normally seen in conventional collagen hydrogels, the surviving cell population recovers during subsequent culture.
