What sort of pressure would be required for a quartz stone to emit electricity and how much?
quartz is igneous; petrified wood is sedimentary
Quartz is a mineral, not a rock. ...and quartz, may be found in metamorphic rocks, but are not necessarily the result of the process of metamorphism. These minerals formed during the crystallization of igneous rocks. They are stable at high temperatures and pressures and may remain chemically unchanged during the metamorphic process. r u satisfied.......or not.............mail if further query.........bye
quartz can be either igneous (quartz vein in igneous rock) metamorphic (quartz forms veins in folds and cleavage) or sedimentary (chert is a chemical or biological sedimentary rock) petrified wood is usually regarded as sedimentary.
This Site Might Help You. RE: can you classify these as either metamorphic, igneous, or sedimentary? the rocks are quartz and petrified wood? plz classify them for me!i need to study 4 my science quiz!
Quartz is a mineral. Petrified wood is kind of a fossil, so you can't really classify them as rocks.
