GEOLOGY - CHAPTER2 (CALCITE)

Question 1

Named as a mineral by Gaius Plinius Secundus (Pliny the elder) in 79 CE from Calx, Latin for Lime, and the
related German word calcit.

Answer 1

CALCITE

Question 2

is a carbonate mineral, meaning that it contains the chemical carbonate

is a rock-forming mineral with a chemical formula of CaCO3.

is the most common form of calcium carbonate.

Answer 2

CALCITE

Question 3

Some geologists consider it to be a “ubiquitous mineral” – one that is found everywhere.

Answer 3

CALCITE

Question 4

Highly transparent calcite is called

Answer 4

optical spar

Question 5

VARIETIES OF CALCITE

Answer 5

Cobaltocalcite
Salmon Calcite
Iceland Spar
Sand Calcite

Question 6

is most often found in a sedimentary settings, especially in marine areas that are not very deep.

• It can also find calcite in hot spring deposits and hydrothermal veins.

Answer 6

Calcite

Question 7

is tested against a cold, dilute (10%) solution of hydrochloric acid (HCl). Observation reveals a reaction that is characteristic of this mineral and helps in identifying calcite.

Answer 7

Calcite

Question 8

is typically white with a transparent look. What sets it apart from other minerals is the perfect
cleavage it has allowing it to form a perfect rhombus. Also, to be certain or to see if a rock contains calcite, we
can put acid on it and it will make little CO2 bubbles. It also has a hardness of 3, which makes it scratchable by
a penny.

Answer 8

Calcite

Question 9

• The construction industry is the primary consumer of calcite in the form of limestone and marble.
• These rocks have been used as dimension stones.
• Modern construction uses calcite in the form of limestone and marble to produce cement and concrete.
• These materials are easily mixed, transported, and placed in the form of a slurry that will harden into a
  durable construction material.
• Concrete is used to make buildings, highways, bridges, walls, and many other structures.

Answer 9

Calcite

Question 10

are group of silicate minerals that have been used since the Bronze Age as gemstones and
abrasives.

The name was coined by a German theologian, Albrecht Von Bollstadt (1193-1280)
