Magnificent Pair of Petrified Wood Logs
Qitai County, Junggar Basin
Xinjiang Uyghur Autonomous Region
This beautifully preserved, silicified coniferous log was cut and polished into a vertical cross-section pair. Discovered in northwestern China, the pair of log sections stands an impressive 9 ft. 3 in. tall. Each section weighs in at approximately 4,000 lbs. The petrified wood is truly alive with colorpossessing a mix of subtle hues that includes red, orange, tan, brown, white, gray and yellow.
The fossilized conifer log was found in a fluvial deposit in the lower part of the Upper Jurassic Shishugou Group. The Shishugou Group gets its name ("stone tree valley") from the many petrified forests contained within it. These amazing forests contain abundant silicified tree stumps and logs.
The word "petrified" comes from the Greek word "rock" or "stone". Petrified wood is essentially fossil wood where the organic materials have been replaced by a series of minerals with quartz being predominant. Impurities in the quartz silica, contributes to the color variation. This process takes place underground in an oxygen free environment where mineral rich water flows over the organic sediment deposits.
The location where these specimens come from has recently been designated a Chinese National Park, thereby prohibiting any further collecting. It is unlikely that another comparable log, from this locality, will ever again be available for public sale. The vertically-cut pair of log sections was professionally stabilized, prepared and polished. One of the log sections was professionally repaired along two fissures. The other log section is unrepaired.
