Solved Identify Igneous Rock 1 O Andesite Gabbro Granite Chegg Fine grained rocks contain minerals too small to be seen with the naked eye, cooling at the earth's surface very quickly. use the information from igneous rock classification chart below to identify the ten unknown igneous rock names (granite, basalt, gabbro, diorite, rhyolite, tuff, scoria, andesite porphyry, peridotite and obsidian). Plutonic or intrusive igneous rocks form when magma cools slowly beneath the earth’s surface, leading to the formation of large crystals. examples of intrusive igneous rocks include: granite: known for its coarse grained texture and used commonly in countertops. gabbro: a dense, dark colored rock, often found in the earth’s oceanic crust. Figure 4.1.1 4.1. 1: granite is a classic coarse grained (phaneritic) intrusive igneous rock. the different colors are unique minerals. the black colors are likely two or three different minerals. if magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. In addition, you may download and print the igneous rock textures photo guide to help you to identify the samples in this lesson. instructions and observations retrieve the bag labeled lab #6 igneous rock samples from your lab kit place the specimens (numbered 1 through 10) on a white sheet of paper. step 2: determine the identity of each rock.
