Download Chemical conglomerate rocks are either inorganic or organic. Both

1. Chemical conglomerate rocks are either inorganic or organic. Both have material carried
in solution which then settles or precipitates. Organic sedimentary rocks are composed of
animal or plant matter which forms strata usually on the floor of oceans or lakes. This
may be created by the shells of molluscs for example. Inorganic sedimentary rocks in
contrast are formed when chemicals and particles are precipitated out of a solution and
form layers on whatever surface they are accumulating. Some inorganic sedimentary
rocks include rock salt, and limestone.
2. These rocks from when layers of their components pile up and form visible strata. This
does not always occur by compression as dried oceans and stalagmites/stalactites occur
by evaporation. Dolostone- Dolostone forms as the magnesium in seawater works its way
into limestone deposits removing some of the calcium.
3. http://en.wikipedia.org/wiki/Limestone
organic limestone- Organic limestone is formed as the carbon skeletons of marine
creatures collect on the bottom of sea floors. Shells and the hard bodies of coral polyps
are excellent for forming limestone
http://en.wikipedia.org/wiki/Limestone
precipitate limestone- near waterfalls hotsprings and certain caves calcium rich water
evaporates or precipitates its calcium content onto surfaces and this eventually builds up
into structures. Stalactites and stalagmites are an example of precipitated limestone.
http://en.wikipedia.org/wiki/Dolostone
Dolostone- dolostone is similar to a limestone composition but contains much more
magnesium instead of lime (the main component of limestone)
http://en.wikipedia.org/wiki/Chert
Chert- chert is a microfiborous rock formed of quartz which is usually found within other
rocks. It may contain fossils and takes on many different names depending on where it is
found.
http://en.wikipedia.org/wiki/Gypsum
Gypsum- gypsum is often found in evaporate beds at the bottom of lakes and seas. It is
often found
with the minerals sulphur and halite. Gypsum
may also be found as a precipitate near volcanic vents.
http://en.wikipedia.org/wiki/Rock_salt
Halite- halite is formed in the precipitate beds of lakes and oceans. When an ocean or
lake dries up there are often deposits of halite left behind along with other minerals such
as gypsum and sulphur.
http://en.wikipedia.org/wiki/Coal
Coal- coal is formed by the death of plants and animals into bodies of water. They must
then be trapped from oxidization by mud or acidic water. As they decompose these
organisms form into massive peat bogs. For coal to occur metamorphosis must occur to
the layer of dead organisms.

4. 4. Evaporites: Deposits where sea basins are draining and evaporating. As new sea water enters, the
water eventually becomes saturated and salt begins to precipitate.
Precipitation: The process that separates solids from a solution. This occurs when a solution becomes
saturated or evaporates.
Karst Topography: a landscape shaped by the dissolution of a layer or layers of soluble bedrock, usually
carbonate rock such as limestone or dolomite
5. V. As a sea is in the process of drying up it often precipitates salt as new water fills it and it
becomes saturated. Animal life in the sea will die as in any body of water and form strata of
limestone. As the sea dries and then more water enters there will be the inclusion of another salt
strata. This would produce limestone and salt layers.
