How are igneous rocks formed in India?

Igneous rocks crystallize from magmatic melts intruded at depth into country strata or extruded as lava at the surface. Igneous rocks that cooled on the surface are termed extrusive. The magma from which they are formed may vary in composition and properties.

Which rocks are found in Punjab?

Will gold ever run out?

Based on known reserves, estimates suggest that gold mining could reach the point of being economically unsustainable by 2050, though new vein discoveries will likely push that date back somewhat.

Can you destroy diamonds?

Crush it. A diamond is one of the hardest materials on the planet, but it’s not indestructible. Due to this property, it’s not easily scratched — but a diamond is still vulnerable to chipping and breakage. Once a diamond is broken, it cannot be repaired, only cut into a smaller jewel.

What is gold’s weakness?

Gold does not react with most chemicals but is attacked by chlorine, fluorine, aqua regia and cyanide and dissolves in mercury. In particular, gold is insoluble in nitric acid, which will dissolve most other metals. Nitric acid has long been used to confirm the presence of gold in items.
