Dinosaur leg bones containing quartz instead of calcium suggest a process known as permineralization, where minerals infiltrate and replace organic material over time. In this case, the original calcium phosphate or carbonates in the bones may have been replaced by silica, forming quartz. This mineral replacement can occur due to environmental conditions, such as the presence of silica-rich waters, which can lead to fossilization. Such findings contribute to our understanding of the fossilization processes and the geological history of the regions where these bones are found.
yes
It is a trace fossil.
No. Quartz is silicon dioxide. Calcium carbonate can form either calcite or aragonite.
A strip or vein of quartz containing gold is called a "reef."
Quartz, feldspars, mica.
Feldspar and quartz are not carbonates (carbonate minerals). They are silicates because they have Silica (Si) in the formula. Quartz is SiO2. Feldspar is a mineral group (feldspars) They have a variable composition that gneerally depends on the amount of Ca, Na or K in their chemical formula. An example of feldspar is Albite NaAlSi3O8. Carbonates have CO3 in their chemical formula. Two examples are Calcite (CaCO3) and Siderite (FeCO3).
Quartz is silicon dioxide (SiO2). Granite is a rock containing many minerals and chemical entities; but granite contain also an important percentage of quartz.
The irradiation of quartz containing traces of aluminum will produce an amethyst gemstone. This process can change the color of the quartz from clear to purple, resulting in the formation of amethyst crystals.

Calcite is the opaque compound calcium carbonate (CaCO3). It will dissolve in carbonic acid and will fizz in stronger acids. Quartz is the usually transparent compound silicon dioxide (SiO2). It will not dissolve in acid.
