Igneous rocks are classified by
texture and mineral composition.
breccia
comglomerate but angular, small pebble pieces
rock salt
pure NaCl
a layered or banded appearance
foliation
limestone
composed chiefly of the mineral calcite- calm shallow seas
other sedimentary rock features
fossils, ripple marks, cross bedding- sand dunes, layers of strata, mud cracks
Crystal
settling can change the composition of magma and cause more than one rock type to form from a common parent magma.
marble
reheated limestone
gneiss
cmes rom granite
The most abundant chemical sedimentary rock is
limestone,
conglomerate
madeby fast moving river, rounded from travel, long time
fast cooling magma
fine grained/ aprthyrite textures
Common detrital sedimentary rocks
shale, sandstone, and conglomerate.
cools in air from volcanix explosion
glassy
Metamorphic rocks
reheat or presurized rocks to form new crystals and deformation (foliations) of a former rock
chert
deposited out of liquid flint,
sandstone
made up of sand (small)
cools slowly, than faster or very fast
large crystals nd small crystals or large crystals and ground mass
Metamorphic rock
forms from rock that has been subjected to great pressure and heat in a process called metamorphism.
Igneous rock
forms from magma that cools and solidifies in a process called crystallization
Slow Cooling magma
course grained
commone metamorhic rocks
gniess, slate, marble
slate
comes from shale
cools in lava surface
vesicles
Sedimentary rock
forms from the lithification of sediment
Gypsum
Depostion of liquid
travertine
(CaCO3)found in caves
shale
(the most common sedimentary rock), mudstone, quiet muddy environment
Compaction and cementation
transform sediment into solid sedimentary rock.
