We often could infer the environment of deposition of the source rock in highly crystallized metamorphic or igneous rocks. It is easier in metamorphic rocks that were heated but not subjected to external fluids (these cause massive chemical changes makes it exceedingly difficult to tell).

But often we can tell what these rocks were prior to modification by zonal metamorphic reworking of sedimentary rocks. Shales under heat and pressure tend to produce schists, whereas, sandstones tend to produce quartzites. We will even see forms of quartz that don't exist in our "reality" by the pseudomorphs they produce. So in this way, the information has not even been lost about where that rock had been even though significant morphological and crystalline changes had occurred. Does that correspond to the idea that "I was a swamp once upon a time" or "I was a beach"? Maybe at a simple level. Now what about entire formations? What are their "memories"? "I was a beach that was heated and compressed,bent by tectonics, subjected to hot silicious geothermal modification that varied considerably in temperature and chemistry." That is my translation of its "thought". Does it have other ideas in it? Perhaps, if information storage, retrieval and utilization is the definition of intelligence.
