Rocks and the Rock CycleChapter 4 Page. 96

There are three main types of rocks:

1. Igneous – rocks formed from magma or lavaClassified based on

A. Origin (Where & How they formed)– Intrusive or ExtrusiveB. Texture (size of crystals/grains)

C. Chemical (Mineral) composition.– (Basaltic or Andesitic or Granitic)

2. Metamorphic – rocks changed from heat and pressure deep underground

Classified based on their texture.– (Foliated or Non-foliated)

3. Sedimentary – rocks formed from compacted sediments Classified based on the composition & origin of the sediments.

– (Detrital or Chemical or Organic)

Classifying Igneous Rocks

IGNEOUS ROCKS - rocks that formed from the cooling and crystallization of magma or lava.

– Igneous rocks are classified three ways;1. by where they were formed (Intrusive or

Extrusive)

2. Texture (size of crystals)

3. by their chemical composition. (Basaltic or Andesitic or Granitic)

Rhyolite

Page 12: Rocks Unit P.94 Set Up Your Cornell Notes Open your big red textbook to page 94. Hand in your progress report Late work is due, grades go in the computer

Igneous Rocks - Origin

1. Extrusive igneous rocks (aka Volcanic rocks) form at the earth's surface as lava cools.– Forms small crystals (can’t see with naked eye).

– These rocks have a fine (small) crystalline texture.

– Examples• Basalt

• Rhyolite

• Scoria (no crystals)

• Pumice (no crystals)

• Obsidian (no crystals)

Page 13: Rocks Unit P.94 Set Up Your Cornell Notes Open your big red textbook to page 94. Hand in your progress report Late work is due, grades go in the computer

Igneous Rocks - Origin

2. Intrusive igneous rocks (aka Plutonic Rocks) form deep underground where magma cools slowly.– Forms large crystals to form that are easily seen.– These rocks have a coarse (large) crystalline texture.

Examples:– Granite– Gabbro

Page 14: Rocks Unit P.94 Set Up Your Cornell Notes Open your big red textbook to page 94. Hand in your progress report Late work is due, grades go in the computer

Igneous rocks are also classified by their chemical composition.

1. Basaltic (aka Mafic) Igneous rocks – composed of mostly Iron (Fe) and Magnesium (Mg).– dark and higher densities

Examples: Basalt, Gabbro

2. Andesitic Igneous rocks (aka Intermediate chemical composition).

– Chemically In between granitic and basaltic.Examples: Andesite, Diorite

3. Granitic (aka Felsic) Igneous rocks– composed mostly of Silicon (Si), Oxygen (O) and Aluminum

(Al).– Light in color and lower densityExamples: Granite, Rhyolite

Metamorphic Rocks P. 110 Metamorphic rocks are rocks that have been changed in form due

to heat, pressure, and chemical alteration deep underground.– They are classified by the arrangement of the mineral grains

1. FOLIATED – The mineral grains flatten and line up in parallel bands or layers.

Examples of foliated Metamorphic Rocks– Slate – Schist – Gneiss

2. NONFOLIATED - Mineral grains change, grow and rearrange but don’t form bands.

Examples of non-foliated Metamorphic Rocks– Marble – Quartzite

Page 18: Rocks Unit P.94 Set Up Your Cornell Notes Open your big red textbook to page 94. Hand in your progress report Late work is due, grades go in the computer

Metamorphic Rocks DO NOT MELT! Minerals can grow larger in size. Elements can rearrange and bond with

different elements in the rock to form new minerals.

– Example : Pick up the Greenstone on your desk

Metamorphic Rocks P. 110

Page 19: Rocks Unit P.94 Set Up Your Cornell Notes Open your big red textbook to page 94. Hand in your progress report Late work is due, grades go in the computer

Metamorphic Rocks P. 110

There are Levels of Metamorphism

– Slate (less heat & pressure)

– Phyllite

– Schist

– Gneiss (more heat & pressure)

Page 20: Rocks Unit P.94 Set Up Your Cornell Notes Open your big red textbook to page 94. Hand in your progress report Late work is due, grades go in the computer

Examples of rocks changing into met. Rocks due to heat and pressure.

– Shale (sed) changes to slate

– Basalt (Ig) changes to schist

– Basalt (Ig) can also change to greenstone

– Sandstone (sed) changes into Quartzite

– Slate (met) changes into phyllite (met) then schist (met) then gneiss (met)

– Granite (Ig) changes into granite gneiss

Sedimentary Rocks P. 102

Sediments are broken pieces of rocks and minerals.– Clay, silt, sand, gravel, cobble, boulder are sizes of

sediments

Weathering is the process of breaking rocks into smaller pieces by wind, water, glaciers and gravity.

Erosion and deposition is the process of MOVING (transporting) these materials.

Page 23: Rocks Unit P.94 Set Up Your Cornell Notes Open your big red textbook to page 94. Hand in your progress report Late work is due, grades go in the computer

Sedimentary Rocks P. 102

Sedimentary Rocks form when sediments are compacted (squeezed) and cemented (glued) together.

Sedimentary rocks can also be formed by evaporation or precipitation from solution.

Most sedimentary rocks are formed of layers of materials that have washed into lakes, rivers, and the ocean.

Page 24: Rocks Unit P.94 Set Up Your Cornell Notes Open your big red textbook to page 94. Hand in your progress report Late work is due, grades go in the computer

There are 3 groups of Sedimentary Rocks 1. Clastic (detrital) Sedimentary Rocks

form from bits and pieces of other rocks. 2. Chemical Sedimentary Rocks consist

of minerals deposited from a solution. 3. Organic Sedimentary Rocks consist of

organic matter such as plants and animal remains.

Sedimentary Rocks

1. Detrital (Clastic) Sedimentary Rocks Rocks formed from the compaction and

cementation of sediments.

Weathering and erosion by gravity, rivers, ice/glaciers, wind, and waves carry sediment.

Examples– Conglomerate– Sandstone – Shale

2. Organic Sedimentary Rocks

Organically-formed sedimentary rocks form from the remains of plants and animals.

Examples Fossil limestone Coal Coquina Chalk

Why can’t igneous or metamorphic rocks have fossils?

Sedimentary Rocks

3. Chemical Sedimentary Rocks

Chemically-formed sedimentary rocks come from minerals carried in solution into lakes and seas.

The minerals that form the rock precipitate out or are left when the solution evaporates.

Examples Limestone (calcium carbonate) Gypsum (calcium sulfate) Salt (sodium chloride)
