Limestone is a sedimentary rock composed largely of calcium carbonate. It forms from skeletal fragments of marine organisms and makes up about 10% of all sedimentary rocks. Limestone erodes over thousands to millions of years through water and weak acids, forming caves and karst landscapes. It has many uses including building material, road base, fillers, and feedstock for other materials. Stalactites form on cave ceilings through dripping water depositing calcium carbonate over time.

Formation of gold
The saying among prospectors that "gold is where you find it" suggests its occurrence is unpredictable, but there is some certain geological environments for the formation.
Because gold is very stable over a range of conditions, it is very widespread in the earth’s crust.
Gold dissolved in warm to hot salty water, the fluids are generated in huge volumes deep in the Earth’s crust as water-bearing minerals dehydrate during metamorphism.
Any gold present in the rocks being heated and squeezed is sweated out and goes into solution as complex ions.
In this form, dissolved gold, along with other elements such as silicon, iron and sulphur, migrates wherever fractures in the rocks allow the fluids to pass.
The direction is generally upwards, to cooler regions at lower pressures nearer the Earth’s surface.
Gold eventually becomes insoluble and begins to crystallize, most often enveloped by quartz.
The association of gold and quartz vein forms one of the most common types of "primary gold deposits".
India
In India, gold mineralization of economic importance is mainly restricted to Archean greenstone terranes of the Dharwar Craton (DC).
The eastern block of the DC has a high favorability for hosting major gold deposits such as Kolar, Hutti, and Ramagiri, whereas the western block hosts only a few smaller deposits such as Gadag, Ajjahanahalli, and Kempinkote.
Gold also discoverrd by GSI in the Singbhum Craton, Aravalli Craton, Bastar Craton and Southern Granulite Terrain (SGT).
India is the second-largest consumer of gold after China.
India currently holds about 558 tones of gold, representing 6.6% of its reserves, (World Gold Council, October 2016).
Kolar Gold Field, Hutti Gold Field and Ramgiri Gold Field are the most important gold fields.
Gold Demand and Use
The largest source of demand is the jewelry industry Gold’s workability, unique beauty, and universal appeal make this rare precious metal the favorite of jewelers all over the world.
Besides jewelry, gold has many applications in a variety of industries including aerospace, medicine, dentistry, and electronics for the manufacture of computers, telephones, televisions...
The third source of gold demand is governments and central banks that buy gold to increase their official reserves.
Private investors there are private investors. Depending upon market circumstances, the investment component of demand can vary substantially from year to year.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. 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.
3. 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

4. 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.

7. 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

8. 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.
9. 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).
10. 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

14. 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.
15. 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.
16. 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.
