Solved Igneous Rock Sample Identification From The Samples Chegg

Solved Igneous Rock Sample Identification From The Samples Chegg Question: part 2: igneous rock identification a) using the nine (9) samples of igneous rock on the next slides (#r1 r9), organize them from most felsic to most mafic. b) where did you rank sample r9? this one is called obsidian and is potentially tricky you'll need to do a bit of research to better understand its texture and composition. Complete this activity using the igneous rock data worksheet provided in the lab 5 module in momentum. column 1. the sample numbers in this column match the samples in lab 5 figures figures 13 and 14. use the enlarged photos in figure 15 to describe the igneous rock properties in columns 2 6. column 2. identify the texture of the rock using.

Solved Igneous Rock Sample Identification From The Samples Chegg Select the answer that best describes the texture and composition of this sample. granite is an intrusive igneous rock and coarse grained. it has a felsic composition. view the image of sample b. this igneous rock that is intermediate in composition and has a coarse grained texture. identify sample b. diorite. Intrusive igneous rocks form as magma cools slowly deep in the earth. the slow cooling allows time for large crystals to form. when mineral crystals are so small that they are only visible under the microscope, the igneous rock formed from quickly cooling lava at earth's surface. these rocks are called extrusive. Rhyolite. note igneous rock field classification is based relative color of the rock, ultramafic rocks tend to be green olive vine or very dark colored. magic rocks are dark colored black and gray. felsic rocks are light colored white tan pink light gray. field identification. what is the texture of rock sample 3. what visible mineral are present. Igneous rocks (fiery rocks) are made when molten material inside or outside the earth cools and becomes solid. this melted rock is called magma when it is inside the earth. when magma finds its way to the surface through cracks or volcanoes, it is called lava. when lava cools on top of the earth’s surface, it forms extrusive, or volcanic.
