What specific implication does the detection of chlorine suggest regarding the condensation temperatures during Mercury's early history?
Answer
It suggests that condensation occurred below approximately 1100 Kelvin.
The presence of chlorine is a crucial diagnostic tool for estimating the thermal history of Mercury's formation environment. Chlorine is a highly volatile element, and its successful retention, evidenced by its current presence, places an upper limit on the temperature experienced by the material that eventually formed the planet's bulk composition. The text specifies that the detection of chlorine implies that the condensation process—the point where gas turned back into solid material—must have occurred at temperatures lower than about 1100 Kelvin, contradicting models requiring sustained, extreme heat for the entire accretion disk region.
