摘　　要：豫西地区地层中赋存有较丰富的硅化木,是重要而又典型的古植物地质遗迹。分析了豫西地区硅化木的分布、赋存层位及特征,研究了赋存硅化木地层的沉积环境,古气候特征以及硅化木的成因。分析研究得出,豫西地区硅化木成因主要为高大的乔木植物、适宜的古气候条件、高浓度的硅质溶液、快速埋藏和缺氧条件。There are abundant silicified wood in the strata of western Henan,which are important and typical ancient plant geological relics.The distribution,occurrence horizons and characteristics of silicified wood in western Henan were analyzed,and the sedimentary environment,paleoclimate characteristics and genesis of silicified wood in the formations of silicified wood were studied.The analysis shows that the genesis of petrified wood in western Henan is mainly tall trees,suitable paleoclimate conditions,high concentration of siliceous solution,rapid burial and hypoxic conditions.
