在新昌早白垩世盆地中存在丰富的硅化木 ,它们是重要而又典型的古植物地质遗迹 .新昌硅化木赋存的地层为早白垩世馆头组 ,其岩石类型包括砾岩、岩屑长石砂岩 /长石岩屑砂岩、粘土岩 ,还有少量的礁灰岩和泥灰岩 .岩石学研究表明 ,它们形成于干燥的快速堆积的山间盆地 ,属河湖相沉积 .新昌硅化木为南洋杉型木 ,生活在热带 -亚热带的气候条件 .结合硅化木特征与地层岩石学研究 ,探讨了新昌硅化木形成的古生态环境 .
There are abundant silicified wood in Xinchang pre-Cretaceous basin, which are important and typical ancient plant geological relics.The strata of Xinchang Silicified Wood are Early Cretaceous Guotou Formation, and its rock types include conglomerate, cuttings length Litho-sandstone / feldspar lithic sandstone, clay rock, and a small amount of reef limestone and marl.Petroleum research shows that they formed in the dry rapid accumulation of mountain basin, is a river lacustrine deposition.Xinchang silicified wood Is Araucaria type, living in the tropical-subtropical climatic conditions.Combined with the characteristics of silicified wood and stratigraphy petrology, discussed the paleoclimate environment formed by the Xinchang silicified wood.
