Cons.Geologists working in the field carry a rock hammer, so they can break off the weathered, outer parts of rocks to see the “fresh,” unweathered rock inside. If you can see and identify the minerals in an igneous rock, you can gain further information about the igneous composition. Igneous rocks with quartz in them are usually felsic.Scratch your mineral across the streak plate with a scribbling motion, then look at the results. Hematite, for example, will leave a red-brown streak. Bear in mind that most professional streak plates have a Mohs hardness of about 7. Minerals that are harder will scratch the place and won't leave a streak. 06.Apr 2, 2021 · Simply take a photo (or upload) of rock and Rock Identifier will tell you all about it in seconds.

Key features: -Easily identify thousands of rocks. -Impressive identification accuracy. -Rich resources to learn about rocks. To identify a mineral, first observe its physical characteristics like hardness, color, streak, luster, cleavage, and specific gravity. Write these traits down, then compare the mineral’s traits to those of known mineral types. Additionally, you can use identification resources like books and flow charts.

Rock identification is a systematic process, requiring concise, accurate descriptions of physical characteristics. This process is called petrography. Geologists use petrographic descriptions to communicate the essential features of rocks in writing (with illustrations / photographs if appropriate).
