Petrified Wood Texas

Petrified Wood – Polished
McLennan County, Texas Fossil 

Quick Facts
Origin: McLennan County, Central Texas
Material: Fossilized Wood (Silicified – primarily Chalcedony/Quartz)
Age: Likely Late Cretaceous to Early Tertiary (approx. 65–100 million years) Habit: Silicified logs, branches, and limb casts; polished slabs and freeforms

THE SPECIMEN
This polished Petrified Wood specimen from McLennan County, Texas displays the rich, earthy color palette typical of Central Texas silicified wood. Polishing reveals:
  • warm browns, reds, and ochres
  • subtle banding or growth‑ring patterns
  • quartz‑rich pockets with soft translucency
  • brecciated or patchwork textures from mineral replacement
The polish brings out a glassy, reflective luster, highlighting the internal structure of the fossilized wood. Many pieces show preserved grain, cellular patterns, or mineral‑filled fractures that add visual depth.
Texas petrified wood is known for its durability, strong color saturation, and excellent polishability, making it a favorite among collectors and lapidary artists.

ABOUT THIS FIND
The Locality
McLennan County sits within the Central Texas geological belt, an area rich in:
  • ancient river gravels
  • silicified mudstones
  • fossil wood deposits
  • iron‑oxide‑bearing sediments
Petrified wood in this region often originates from ancient floodplains and river systems where fallen trees were rapidly buried and later replaced by silica.
T
he Formation
Petrified wood forms when buried wood is infiltrated by silica‑rich groundwater. Over millions of years, silica replaces the organic material cell by cell, preserving:
  • growth rings
  • bark texture
  • internal grain
  • natural fractures
Iron oxides, manganese, and other minerals contribute to the warm, earthy coloration seen in Texas specimens.
Polishing enhances these features, revealing the fossil’s internal architecture in stunning detail.

MINERALOGY
Composition: Silicified wood — primarily Chalcedony and Quartz (SiO₂)
Crystal Habit: Massive; wood structure preserved as microcrystalline quartz.
Coloration: Common tones include:
  • brown
  • red
  • tan
  • yellow
  • cream
Color is influenced by iron, manganese, and other mineral inclusions.
Luster: Vitreous when polished; matte when raw.
Stability: Very durable (Mohs 6.5–7); excellent for display and lapidary use.
