Petroleum Quartz
Also known as: Petroleum included quartz, Oil quartz, Hydrocarbon quartz
Variety of Quartz.
📜 Key facts
| Age | The quartz and its oil inclusions formed in sedimentary rocks millions of years ago |
|---|---|
| Origin & sources | Balochistan (Baluchistan), Pakistan. Also Herkimer, New York (with black bitumen). |
| Composition | Quartz (SiO₂) with fluid inclusions of liquid petroleum, often with gas bubbles that move and black bitumen |
How it forms
As quartz crystals grew in oil-bearing rock, they trapped droplets of crude oil, water and gas. Under longwave UV the oil inclusions fluoresce, often blue, blue-white or yellow.
Mineral data: see Quartz.
✺ Glows under UV
| Longwave UV (~365 nm) | Oil inclusions glow blue, blue-white or yellow |
|---|
The quartz itself doesn't glow. The trapped droplets of petroleum fluoresce, so the inclusions light up inside the clear crystal.
Reactions vary by locality and specimen; many specimens of a fluorescent species do not glow. Shortwave UV can burn skin and damage eyes. Wear UV-blocking glasses, and never look into any UV lamp. Sources: Wikipedia: Fluid inclusions. More UV-reactive stones →
