辽东本溪-桓仁地区古生界事件地层划分及特征

辽东本溪-桓仁地区古生界发育，是研究地层学、沉积学的典型地区.在简述事件地层学原理和地层事件概念，并对主要地质事件进行初步划分基础上，通过对本溪-桓仁地区1：5万区域地质调查、地层剖面测制研究，对该区古生界，根据地质事件的岩石记录，划分了构造上升和下降、海侵、缺氧、风暴、干燥炎热等6种事件地层单位，8个事件集群，并对各事件地层单位逐一描述，提出事件个体和事件集群、事件沉积层和事件集群沉积段的概念，并探讨了与沉积环境、层序地层的相关性.

EVENT STRATIGRAPHY OF THE PALEOZOIC ERATHEM IN BENXI-HUANREN REGION,EASTERN LIAONING PROVINCE: Division and Characteristics

Benxi-Huanren in eastern Liaoning Province, where the Paleozoic strata are well developed, is a typical area for stratigraphic and sedimentological study. Based on the theory and concept of event stratigraphy and division of main geological events, with the 1:50000 regional geological survey and stratigraphic section measurement, the Paleozoic strata in the region is divided into 6 event stratigraphic units, i.e. tectonic uplift, depresion, transgression, hypoxia, windstorm and hot arid, and 8 event clusters. The authors describe each event stratigraphic unit individually, present the concepts of event individual, event cluster, event sediment and event cluster depositional segment, and discuss its correlation with sedimentary environment and sequence stratigraphy.
