摘要
硅化木分布于我国新疆、浙江等20余省,规模、数量巨大,颜色绚丽。矿物成分以石英及其变种为主,含10多种微量元素和多种氨基酸,主要形成于侏罗纪、白垩纪。其成因是在有大量树木资源,适宜古气候及丰富的高浓度可溶性S iO2等环境中快速缺氧埋藏综合作用的结果。具有重要的科学、经济价值。
Silified wood is widespread in Xinjiang,Zhejang and other more than 20 provinces in China.It has large scale and volume with magnificent color.The mineral compositions are quartz and its varieties.It contains more than 10 kinds of trace elements and many amino acid.The formation period is Jurassic and Cretaceous.The genesis is the result of complex effects with mass wood resource growing in favorable climate and being quickly buried in anaerobic environment where there is highly concentrated soluble SiO2.The perspective of development and utilization of silified wood is very entensive with important scientific and economic value.
