Rocks are solid masses composed of combinations of minerals, while minerals are naturally occurring inorganic compounds with unique chemical structures and physical properties. For example, quartz and feldspar are minerals that together form the rock granite. Minerals are identified based on their physical properties, including luster, transparency, color, streak, cleavage, fracture, hardness, and other characteristics like magnetism, acid reaction, taste, and feel. Proper identification requires examining multiple properties rather than relying on any single characteristic like color alone.
Rocks and Minerals
A mineral is a naturally occurring inorganic compound with a unique chemical structure and physical properties.
A rock is a solid, stony mass composed of a combination of minerals or other organic compounds.
For example, quartz and feldspars are minerals, but when formed together, they make a rock, granite”
To determine if an Earth rock is a mineral, it should exhibit the following characteristics
Naturally occurring
Inorganic
Can be represented by a chemical formula
Crystalline structure
Solid
Most minerals form by inorganic processes but some, identical in all respects to inorganically formed minerals, are produced by organic processes
Transparency describes how well light passes through a mineral sample
There are three degrees of transparency: transparent, translucent, and opaque.
Habit of a mineral may be define as the size and shape of the crystal, and the structure of form shown by the crystal.
1. Accicular minerals showing needle like crystal. E.g. natrolite
2. Fibrous minerals showing an aggregate of long thin fibers. E.g. Asbestos
3. Tabular minerals showing bladed habit occur as small knife blades. E.g. Kyanite
4. Granular minerals which occur as aggregate of equidimensional grains. E.g. chromites
5. Pisolitic minerals which occur as aggregate of rounded grains of a pea size. E.g. oolite
6. Columnar minerals showing columnar crystal. E.g. tourmaline
Minerals strength determines how easy the mineral breaks or deforms when exposed to stress.
Reaction with Acid. Some minerals, especially carbonate minerals, react visibly with acid. (Usually, a dilute hydrochloric acid [HCl] is used.)
When a drop of dilute hydrochloric acid is placed on calcite, it readily bubbles or effervesces, releasing carbon dioxide
Mineralogy
Definition of mineral, mineralogy, Importance of study of minerals: rock forming and ore forming minerals. Different methods of study of minerals. Study of minerals by physical identification method and their physical properties.Forms and Habits, Colour, Streak, Lustre, Fracture, Cleavage, Hardness, Specific Gravity, Degree of Transparency, Special Properties Determination of Physical properties of following minerals: Feldspar, Quartz, Flint, Jasper, Olivine, Augite, Hornblende, Muscovite, Biotite, Asbestos, Chlorite, Kyanite, Garnet, Talc, Calcite. Study of ore forming minerals such as Pyrite, Hematite, Magnetite, Amethyst, Galena, Pyrolusite, Graphite, Magnetite, and Bauxite, Coral reefs.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
