Chapter 4 Rocks and Minerals Oregon State University

Chapter 4 Rocks and Minerals. Chapter 4 focuses on Rocks and Minerals, looking at types of rocks. The lava has cooled and is now a volcanic rock called basalt. The weathering process will break the basalt down into small, finer pieces of rock called soil. They also contain potassium and plagioclase feldspar with a small amount of quartz.

Basalt

By definition, basalt is an aphanitic (fine grained) igneous rock with generally 45 53% silica (SiO2) and less than 10% feldspathoid by volume, and where at least 65% of the rock is feldspar in the form of plagioclase. This is as per definition of the International Union of Geological Sciences (IUGS) classification scheme.

Basics Igneous Rock Table Wenatchee Valley College

Igneous rock is solidified magma. Plutonic igneous rock comes from magma that intrudes within the earth, deep underground, and cools and crystallizes there. Volcanic igneous rock originates from magma that erupts, as either lava or as tephra, and turns solid on the earth's surface.

Plagioclase the white or chalky looking grain is the common feldspar, plagioclase. Plagioclase is the most common mineral in igneous rocks. The illustration to the left shows a large chalky white grain of plagioclase. The chalky appearance is a result of weathering of plagioclase to clay and this can often be used to aid in identification.

Explain how and why the plagioclase feldspar in basaltic

Jan 31, 20120183;32;Best Answer The difference has to do with the change in chemistry of the magma body as crystallization proceeds. Bowen's Reaction Series shows that the first plagioclase feldspars that form are rich in calcium and very poor in sodium. Crystallization at this early stage would produce rocks that are rich in calcium plagioclase feldspars and be basaltic (mafic) in composition.
