Answer 2

never heard the this term for petrified wood. Seems a little illogical.You can have parental magma, which is the magma from which an igneous rock was formed and parent elements when referring to radioactive decay. But the parent to petrified wood was not a geological formation or rock.

try here, maybe I missed something.

Answer 3

I have never heard the term "parent geologic formation", but parent usually refers to the source rock (or atom or whatever else) and daughter refers to the final rock. I assume that the original geologic formation contained the wood which was then reworked into another environment.
