gabbro has the following properties: solid no fixed crystal structure not made by organisms naturally occurring not a pure substance coarse - grained texture. is gabbro a mineral, a rock, or neither? mineral rock neither
Answer
Answer:
rock
Explanation:
Step1: Recall mineral properties
Minerals have a fixed crystal - structure and are pure substances. Gabbro has no fixed crystal structure and is not a pure substance, so it's not a mineral.
Step2: Recall rock properties
Rocks are naturally occurring, solid materials that are not made by organisms and can be coarse - grained. Gabbro meets these criteria, so it is a rock.
