I have very little knowledge of this, but I will say chemicals have different properties. For instance the solid of H2O floats as opposed to sinks in its liquid form. I suspect we can narrow out options for the formations. However, we will never be 100% confident (but maybe 80+% confident) in what has occurred.

Geochemistry is a lot more concrete than that, from my exposure to it. Mars also doesn’t have an exotic composition or environment for a liquid solid gas phase of something else.
