摘要
著重介绍太原西山和晋东南石炭—二叠系上、下部煤岩组合所夹酸性火山事件等时层的 γ曲线特征 ,依此可将太原西山毛儿沟、庙沟灰岩与晋东南松窑沟灰岩对比 ,将太原西山东大窑灰岩与晋东南红矾沟灰岩对比 ,其上下煤层依 γ曲线和结构特征对比 ,太原西山山西组三尺炭与晋东南香煤对比。
The main emphasis is given to the γ curve features of the isochronous beds in the acidic volcanic event of the upper and lower parts of the Carboniferous—Permian in Xishan of Taiyuan and in the southeast of Shanxi Provence. Based on this, some correlations may be made between the Maoergou and Miaogou Limestones in Xishan of Taiyuan and the Songyaogou Limestone in the southeast of Shanxi; between the Dongdayao Limestone in Xishan of Taiyuan and the Hongfanggou Limestone in the southeast of Shanxi; between the coal seams above them and these below them on the basis of features of the γ curve and structure; and between the “Sanchitan” Coal Seam of the Shanxi Formation in Xishan of Taiyuan and “Xiangmei” Coal Seam in the southeast of Shanxi.
