In order to study biostratigraphy and chemical stratigraphy during the Lower Kellwasser event, high resolution conodonts research and chemostratigraphic framework were carried out. The data reveals that the inorganic and organic carbon isotope have a significant positive excursion at the bottom of the Laye section. It is considered that the sample LY-8 is consistent with the Lower Kellwasser boundary. The main reason for the change of carbon isotope in this area is the increase of organic carbon burial, which is caused by the increase of marine primary productivity and anoxia environment possibly.

Owing to the existing management modes sometimes appear passive effects in work efficiency, in-depth research and informatization degree, a comprehensive management platform of geological data informatization is established. According to the experience of experts, the authors design the general architecture and function modules of the platform, and build a geological database. The system possesses the function of geological data management and maintenance, geological map management and maintenance, integrated information query, user interaction and communication, numerical analysis, data chart and as well as security control. The application shows that the system runs steadily, manages geological data efficiently, greatly improves the efficiency and quality, and provides technical support for the realization of a digital, standard and modern management of geological data.
