Question
Fly to Half Dome in Yosenite National Park. Here you see a beautiful exposure of the Sierra Nevada Batholith. This batholith consists of multiple plutons that intruded into the area as part of a Mesozoic-age subduction system Given that Half Dome is part of a batholith, a large intrusive igneous body, what type of rock texture would you expect to see at Half Dome? aphanitic (fine-grained) O phaneritic (coarse-grained) glassy O fragmental 2 poi QUESTION 2 Half Dome as well as the bulk of rock that comprises the entire Sierra Nevada range is largely granite. Out of the choices below, which minerals are typically found in granite? l. Mica ll. Halite ll. Plagioclase Feldspar 1. Pyrite V. Quartz Vi. Orthoclase Feldspar Save All Answers Click Save and Submit to save and submit. Click Sove All Answers to sove all answersExplanation / Answer
Answer 1 : phaneritic texture.
Since batholiths are plutonic intrusive rocks, they contain minerals of coarse grained sizes. Because plutonic rocks cool slowly forming coarse grained crystals.
Answer 2: quartz , orthoclase felspar and plagioclase felspar , mica
Granite is a coarse grained plutonic igneous rock. The major minerals are quartz feldspars and minor minerals include pyroxenes, mica and zircon etc.
