LIMESTONE ROCKS   LIMESTONE CHALK
Limestone

 Limestone is a sedimentary
 rock composed largely of the
 minerals calcite and
 aragonite, which are different
 crystal forms of calcium
 carbonate (CaCO3). Many
 limestones are composed from
 skeletal fragments of marine
 organisms such as coral or       CAco3 Molecular Structure
 foraminifera.
Erosion of limestone

 Limestone makes up about
 10% of the total volume of
 all sedimentary rocks. The
 solubility of limestone in
 water and weak acid
 solutions leads to karts
 landscapes, in which water
 erodes the limestone over
 thousands to millions of
 years. Most cave systems
 are through limestone        Erosion of limestone

Limestone

 Limestone has
 numerous
 uses, including as
 building material, as
 aggregate to form the
 base of roads, as white
 pigment or filler in
 products such as
 toothpaste or             A building made up of limestone

 paints, and as a
 chemical feedstock.

Limestone in middle ages

 Limestone was also a
 very popular building
 block in the Middle
 Ages. Many medieval
 churches and castles in
 Europe are made of
 limestone. Beer stone
 was a popular kind of
 limestone for medieval
 buildings in southern
 England.                  Sydoriv Castle, in Ukraine
                           Made up of limestone
Limestone Caves

 A stalactite is a type of
 speleothem (secondary
 mineral) that hangs
 from the ceiling of
 limestone caves. It is a
 type of dripstone. The
 corresponding
 formation on the floor
 of the cave is known as      Limestone Cave in U.S.A
 a stalagmite.
UNDERGROUND LIMESTONE FEUTURES

 Stalactite:
 They are formed when rain
  water falls from the roof of
  the cavern evaporating the
  water and depositing calcium
  carbonate(calcite).
Limestone Chalk

                   Chalk is a soft, white, porous
                   sedimentary rock, a form of
                   limestone composed of the
                   mineral calcite. It forms
                   under reasonably deep
                   marine conditions from the
                   gradual accumulation of
                   minute calcite plates shed
                   from micro-organisms called
                   coccolithophores. Chalk can

UNDERGROUND LIMESTONE FEUTURES


 Cavern:
 They are created when water
 runes underground and a
 chemical reaction causes
 limestone to be eroded, this
 continues to create a cavern.

            CHEMICAL WEATHERING
Chemical weathering is the process at which limestone
      is weathered to create caverns and caves.

UNDERGROUND LIMESTONE FEUTURES

 Malham cove:
 It has 3 types of rock: Silurian
  limestone, Combrifirous limestone, Bowland Shales.
 There is impervious rock where the surface rivers are
  and then porous rock where the swallow holes are
  this allows for the erosion of the limestone so cave
  and caverns can be created. This is
   essential for the creation of stalagmites
  and stalactites.
USES OF LIMESTONE

 It is the raw material for the manufacture
    of quicklime (calcium oxide), slaked lime(calcium
    hydroxide), cement and mortar.
   Pulverized limestone is used as a soil conditioner to neutralize
    acidic soils.
   It is crushed for use as aggregate—the solid base for many
    roads.
   Geological formations of limestone are among the
    best petroleum reservoirs;
   As a reagent in flue-gas desulfurization, it reacts with sulphur
    dioxide for air pollution control.
   Glass making, in some circumstances, uses limestone.
   It is added to toothpaste, paper, plastics, paint, tiles, and
    other materials as both white pigment and a cheap filler.
USES OF LIMESTONE

 It can suppress methane explosions in underground coal
    mines.
   Purified, it is added to bread and cereals as a source of
    calcium.
   Calcium levels in livestock feed are supplemented with it, such
    as for poultry (when ground up).
   It can be used for remineralizing and increasing the alkalinity
    of purified water to prevent pipe corrosion and to restore
    essential nutrient levels.
   Used in blast furnaces, limestone extracts iron from its ore.
   It is often found in medicines and cosmetics.
   It is used in sculptures because of its suitability for carving.
