Description :
This long, fibrous piece is classic petrified wood.
You can tell by the linear grain and the way the structure looks like frozen wood fibers turned to stone. Plainly: It’s fossilized wood where silica replaced the original organic material. The texture preserves the grain of the tree. Hard, dense, and usually quartz-based. This reddish-brown piece with sparkly points is an iron-rich rock coated with tiny quartz crystals. Plainly: The brown comes from iron oxides. The glittery surface is quartz druse. It formed when silica-rich fluids coated an iron-bearing rock. This white, chalky, porous stone is a soft sedimentary rock.
It could be chalk, limestone, or a weathered tuff. Plainly: Light in weight. Powdery or porous texture. Formed from compacted fine sediments or volcanic ash. This dark piece with a crystalline border is a cut nodule or geode. Plainly: The outer part is solid chalcedony or agate. The inner rim shows quartz crystals. It formed when minerals filled a cavity inside rock.Top Specimen — Petrified Wood (Fibrous Slab)
Left Specimen — Iron-Rich Mineral With Quartz Druse
Right Specimen — Light, Porous Sedimentary Rock
