Marlstone samples from the Early Cretaceous Shangkuh Formation in the Jianzishan section and geological pits in Dawu＇ergen were analyzed systematically using the polarizing microscope, fluorescence microscope and freezing-heating stage.

利用偏光显微镜、荧光显微镜和冷热台对大乌尔根尖子山剖面和地质浅井早白垩世上库力组的泥灰岩样品进行了系统研究。

In practical study, the essential flow is""on the basis of the study of the faults, strata denuded thickness and original thickness, analyzing the controlling effect of the faults to the sedimentation and denudation, and combined with the areal geology background, reconstructing the basin prototype of each stage"". 2. As the basic theories and methods of the calculation of the denuded thickness, such as, the methods of cosmogenic nuclides, wave equation, apatite fission track, structural sections, acoustic wave, vitrinite reflection, etc, were argued detailedly , and their applicable ranges were analyzed , the denuded strata thickness of each structural layer layer of pre-Tertiary was reconstructed.

对宇宙成因核素法、波动方程法、裂变径迹分析法、构造横剖面法、声波时差法、镜质体反射率法等计算剥蚀量方法的基本原理进行充分论证、改进，分析了各方法的适用范围，在此基础上，综合充分运用上述方法，计算了济阳坳陷前第三系各构造层在不同时期的剥蚀量，绘制了中生代时期古生界顶面的地层剥蚀量等值线图、新生代时期古生界顶面的地层剥蚀量等值线图、白垩纪沉积时侏罗系剥蚀等值线图、新生代沉积期白垩系剥蚀等值线图、新生代沉积期侏罗系剥蚀等值线图等图件，并通过对古生界地层的热变质程度分析，确定了有1500～2000m的早、中三叠世的原始沉积地层在晚三叠世被剥蚀殆尽。3。

The study of natural fullerenes is a new area of across fullerene science and geological science. So far natural fullerenes have been found in shungite, fulgurite, carbonaceous conglomerates in impact crater, E/K boundary carbonrich clay rock layer, T/P boundary layer, dinosaur eggshell, coal, heavy crude oil, solid bitumen and socalled seminatural fullerenes in common soots, Chinese ink sticks, commercial char, et al., only with low concentrations.

天然富勒烯研究是富勒烯科学和地质科学相交叉的一个新兴研究领域，迄今为止已在桑加岩、闪电熔岩、陨石撞击坑中的含碳质角砾岩、古近系/白垩系地层界线的含碳粘土岩、三叠系/二叠系界线岩石、恐龙蛋壳、煤、重质油、固体沥青以及半天然的烟灰、木炭、书墨等物质中检测到富勒烯的存在，但含量很低。
