本文介绍了中国煤系高岭岩资源概况、研究简史；根据成分、结构、地质产状等特征，提出了中国煤系高岭岩的成因类型；对生物和有机质在其形成中的作用进行了分析和探讨，并结合有机酸溶解矿物模拟实验对其成矿作用做了初步探索；最后对煤系高岭岩的某些关键性加工技术进行了简述。

The kaolinitic tonsteins, the kaolinitic rocks not adjacent to coals and soft kaolin were studied in this project. The studies show that the materials forming the kaolinite come from the volcano ashies, terrigenous transportation and the solution precipitation of the rocks surrounding the weathering coals.

本项目对我国煤系夹矸高岭岩、煤层不相邻高岭岩和煤系软质高岭土进行了详细研究，认为成矿物质主要来源于火山灰、陆源搬运产物以及煤层围岩物质的溶解沉淀。

This application focuses on the aspects of chemical variation rule of rocks and mineral composition changes of mylonites corresponding to the ductile shearing by the case study in the ductile shear zones in south Tan-Lu fault belt. The results show that there exists evendent variation between deformed and undeformed rocks in ductile shear zones, i.e., the decreasing of SiO2 and alkali elements as well as the large ionic lithophile elements, such as Rb,Sr,Ba. The total REE has the behavoir of increasing during the deformation.

本研究着重选择郯庐断裂带南段广泛出露的中深层次韧性剪切带作为研究对象，系统研究剪切带内外变形条件对岩石化学成分变异规律、研究糜棱岩中变形矿物的化学成分随剪切应变作用的对应关系韧性剪切带内，随着变形程度的增加，韧性剪切带糜棱岩中一些常量元素、微量元素和稀土元素和应变强度之间存在明显的对应关系，主要表现SiO2 和碱金属和大离子亲石元素如Rb，Sr和Ba的亏损以及REE总量增加。

In addition, there are a significant amount of inherited zircons at the age of ?2.7Ga, which indicates that the granitoids may be the products of remelting of former crustal rocks and the Jiaodong Comples-Group is the major component of the source rocks.

其中存在年龄为2.7Ga左右的继承性锆石，这显示了这些花岗岩类为壳源重熔的产物，而胶东岩群可能为其重要源岩之一。
