Granite is heavy and brittle. Instead, take a plate made of platinum or iridium, and engrave information on it. It offers excellent mechanical, chemical, and thermal durability. It can sink in volcanic lava and then hammered back out from the resulting rock, intact. (Expensive though.)

Archival data should never be made on intrinsically valuable material; doing so makes it subject to theft or re-use for something "better". Example: There is a reason why more marble statues survive from antiquity than bronze statues.... Bronze has an intrinsic value (theft) and future artists would also melt down existing bronze statues to make something "better".
