Igneous Rocks: It crystallizes from molten magma.
Metamorphic Rocks: Formed under intense heat and pressure.
Sedimentary Rocks: Found in sands, clays, and even as fossils.
Abundance
Quartz makes up around 12% of the Earth’s crust, a testament to its importance in geology. Its durability ensures its persistence in diverse environments.
Physical and Chemical Properties of Quartz
Key Characteristics
Hardness: Quartz ranks 7 on the Mohs scale, making it resistant to scratches.
Transparency: Ranges from opaque to translucent to clear.
Color Variations: From milky white to vibrant purples, greens, and beyond.
Piezoelectric Effect
Quartz’s ability to generate electricity under pressure is revolutionary. This property powers devices like watches, microphones, and sonar systems.
Types of Quartz
Macrocrystalline Quartz
Visible crystals, such as:
Amethyst: Purple-hued and prized in jewelry.
Citrine: Golden-yellow and vibrant.
Rose Quartz: Soft pink and often associated with love.
Cryptocrystalline Quartz
Microcrystalline forms like:
Chalcedony: Used in carvings and ornaments.
Agate: Known for its colorful bands.
Jasper: A dense, opaque variety with earthy tones.
