We find that in lavas, rocks that generally have a low volume of pores, these fluids create new pathways to flow through by dissolving the rock-forming minerals. In contrast, fluid pathways in tuffs, which are inherently highly porous rocks, are blocked by the precipitation of new minerals in the pore spaces.

Metamorphic Rocks Lesson #14 | Volcano World | Oregon State University

Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. Igneous rocks form when rocks are heated to the melting point which forms magma. Sedimentary rocks are formed from the cementing together of sediments, or from the compaction (squeezing together) of sediments, or from the recrystallization of new mineral grains which are larger than the original crystals. Metamorphic ...

A device called a core catcher pulls the rock samples back up the pipe string to the ship, so scientists can analyze them.
