Earth

Metallic & Non-metallic are descriptions of

Olivine cools and becomes unstable thus at low temps we have quartz or biotite/muscovite.

A rock that is Porphyritic and intermediate

(Chemical) Fine to coarse crystalline and composed of Halite

Regional rocks include

Shows the sequence in which minerals crystallize from lava

A rock that is Aphanitic and mafic is

(Contact) Parent rock bituminous coal and is black

Atomic number

The most important agent and provides energy to drive chemical reactions.

Originate from soluble material produced by chemical weathering

The tendency for a mineral to break along planes of weakness

A rock that is aphanitic and felsic is

The silicon-oxygen tetrahedron contains

Contact metamorphism produces foliation

The tendency of a Mineral to break irregularly or conchoidal under stress

which mineral has cleavage in 6 directions

Contain large amounts of quartz and potassium feldspar

(regional) Shale-->Slate-->phyllite-->Schist-->Gneiss

Striations are straight lines that are close together seen in reflected light on which mineral?

Whats needed

(Clastic) Medium and identified by sand particles

Angular particles

high temps calcium rich plagioclase feldspar and and at low temps sodium rich plagiocioclase

Comes from the weight of overlying sediment or stress from mountain building events.

Dominated by clay and quartz rock fragments

Atomic mass number

The agents of metamorphism

Current strength - stronger current = larger particle size

(Chemical) Microcrystalline and composed of Quartz

A rock that is aphanitic and Intermediate is

Chemical- Composed of calcite and fine to coarse crystalline texture

Thread like markings are seen on the reflected surface of which mineral?

size of the grains or fragments

Which mineral releases a sulfur smell when in contact with HCL

minerals recrystallize with an orientation perpendicular to the dir. of the force.= foilation

(chemical)- Composed of Calcite with Visible shell fragments

Contains biotite, hornblende and plagioclase feldspar

Which mineral is the most magnetic

Originate from solid particles of weathered rock

A rock that is Phaneritic and Mafic is

(Clastics) Coarse and identified by rounded particles

Coarse grained texture. Magma cooled slowly and produces extrusive igneous rocks.

Layered or banded look. visible minerals with parallel alignment.

(Clastic) Coarse and identified by angular particles

A mineral is defined as :

Basic building blocks of minerals

Which mineral bubbles violently when in contact in with HCL

(Clastic) Fine and identified by mud particles

Micas are flexible and include

A glassy rock would include

Heat and Fluid Contact

Chemical/ Non- Clastics

The size of particles can tell us things about the history of the rock

Regional Rock with visible minerals (muscovite)

(Contact) Parent Rock sandstone and has interlocking quartz grains

(Chemical) Composed of Plant fragments and varies textures

Rocks that have changed form

(contact) Parent rock is limestone and identified by Hcl

Igneous rock composition is determined by

Heat and Pressure

Rock comes into contact with magma & is baked. unstable minerals recrystallize to stable minera

Tenacity can be defined as

Round particles

Which minerals have a rhombedral shape

Which Mineral has a soapy feel?

The shape of a mineral is based on what

A rock that is Phaneritic and Felsic is

Contains olivine, calcium rich plagioclase feldspar.

Water is the most common and acts as a catalyst by aiding migration of ions.also involves magma

The mineral Fluorite has 8 sides

Metamorphic rocks are classified by their texture

low grade Regional rock that is hard and looks like shale

Which Mineral has a greasy feel and can write on paper

Which Mineral is the least Magnetic

high grade Regional rock with banding

Common silicates include

A vesicular rock includes

(Chemical)- Composed of Calcite and microscopic shells

Fine grained groundmass or matrix with large minerals called phenocrysts. 2 stages of cooling.

Fine grained texture, lava cooled fast and produced extrusive igneous rock

A rock that is Phaneritic and intermediate is

(Chemical)- Composed of calcite with various size shells

formed from sediment derived from the weather or igneous or metamorphic rocks

Rocks composed of different minerals. Form from crystallization of molten material.

Regional rock that has a silky appearance
