给出了利用晚中生代中国东部高原北缘的气孔状玄武岩定量研究古高程的结果.在厚约3m的熔岩流顶部和底部分别采集了2块玄武岩样品,将玄武岩切面数据化处理后,通过体视学转化法获取到气孔尺寸的大小,最后利用气孔状玄武岩古高程计法计算了晚中生代中国东部高原的古高程.结果显示,该玄武岩喷发时的古高程约4700±750m,表明晚中生代时期中国东部地区的确存在一个地理海拔较高的古地貌.
The results of quantitative study of paleotemperatures by using stomata-like basalts in the northern Mesozoic in the northern Mesozoic in the Late Mesozoic are presented. Two samples of basalts were collected at the top and bottom of lava flows with a thickness of about 3 m. After basalts were digitized, According to the method of visual conversion, the ancient pore size was obtained, and the paleo-elevation basal paleo-elevation method was used to calculate the paleo-elevation of the late Mesozoic plateau in eastern China. The results show that the paleo-elevation at the time of eruption of this basalt is about 4700 ± 750m, There is indeed an ancient geomorphological elevation in the eastern part of China.
