Non-fossiliferous Pink Granite (Pseudofossil specimen)
Inorganic crystalline structure (Potassium Feldspar, Quartz, and Biotite) • Mineral/Rock Specimen (Not a biological fossil); Igneous rock
Geological Period
Precambrian (typically Proterozoic era)
Estimated Age
500 to 2,500 million years (Typical age for continental granitic basement rock)
Preservation Type
None (Igneous crystallization from molten magma; not a preserved organic remain)
Condition Assessment
Good (as a mineral specimen); shows natural fracturing and fresh crystalline faces.
Taxonomic Classification
Abiotic (Phylum: N/A, Class: Igneous Rock, Family: Acidic Plutonic)
Morphological Description
Phaneric crystalline texture with large, interlocking crystals. Features salmon-pink orthoclase feldspar, translucent grey quartz, and black flecks of biotite mica or hornblende.
Rock Matrix
Igneous matrix comprising approximately 65-70% feldspar and 20-30% quartz with minor ferromagnesian minerals.
Formation & Location
Continental crustal shields (e.g., Canadian Shield, Scandinavian Shield, or various mountain ranges worldwide)
Size & Dimensions
Approximately 8-12 cm in width; typical of hand-sample mineral specimens.
Value & Rarity
Estimated Market Value
$5 - $15 USD (Decorative or educational value only)
Auction Estimate
$10 - $30 USD (Small natural history or educational auctions)
Rarity Assessment
Common (Granite is the most abundant rock type in the Earth's continental crust)
Scientific Significance
Provides data on volcanic/plutonic history and tectonic plate movements rather than biological evolution.
Preparation Recommendations
No paleontology preparation required. Can be cleaned with water; store in a dry environment to prevent weathering of mica.
Notable Features
The specimen exhibits high potassium feldspar content giving it a distinct pink hue; lack of bedding or organic structures confirms its igneous origin.
