2. Cataclasite - Wikipedia

   en.wikipedia.org/wiki/Cataclasite

   Cataclasite is a cohesive granular fault rock. [1] Comminution, also known as cataclasis, is an important process in forming cataclasites. [2] They fall into the category of cataclastic rocks which are formed through faulting or fracturing in the upper crust. [3] Cataclasites are distinguished from fault gouge, which is incohesive, and fault ...

3. Carrara marble - Wikipedia

   en.wikipedia.org/wiki/Carrara_marble

   Carrara marble, or Luna marble to the Romans, is a type of white or blue-grey marble popular for use in sculpture and building decor. It has been quarried since Roman times in the mountains just outside the city of Carrara in the province of Massa and Carrara in the Lunigiana, the northernmost tip of modern-day Tuscany, Italy.

5. Quartz monzonite - Wikipedia

   en.wikipedia.org/wiki/Quartz_monzonite

   Quartz monzonite. Quartz monzonite is an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. It is typically a light colored phaneritic (coarse-grained) to porphyritic granitic rock. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase.

6. Quartz - Wikipedia

   en.wikipedia.org/wiki/Quartz

   Quartz is a hard, crystalline mineral composed of silica ( silicon dioxide ). The atoms are linked in a continuous framework of SiO 4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2. Quartz is, therefore, classified structurally as a framework silicate mineral and ...

7. Quartz clock - Wikipedia

   en.wikipedia.org/wiki/Quartz_clock

   Quartz clocks and quartz watches are timepieces that use an electronic oscillator regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks and watches are at least an order of magnitude more accurate than mechanical clocks. Generally, some form of digital logic ...
