济南市长清张夏-崮山地区华北寒武系地质遗迹特点及保护现状

Geological Trace Characteristics and Present Protection Condition of Huabei Cambrian in Changqing Zhangxia—Gushan Area of Jinan City

长清张夏崮山地区寒武纪地层发育 ,出露完好 ,接触关系清楚 ,岩石类型和沉积构造现象丰富 ,古生物化石富集 ,保存完整 ,研究历史悠久 ,是进行层序地层学 ,多重地层划分对比、研究的理想地区 ,是进行地质科学教育的良好基地 ,是不可多得的“地学实验室”。这里早己被确定为“华北寒武系标准剖面” ,并己列入我国地学教科书。2 0 0 1年被批准为省级地质遗迹自然保护区。对该地质遗迹实施有效保护 ,具有重要意义。

Cambrian strata developed and cropped out well in Zhangxia and Gushan area of Changqing with clear contacting relation. Rock types and sedimentary structure are rich, palaeobio-fossils are concentrated and kept well, and has a long study history. It is an ideal area for contrasting and studying sequence stratigraphy and multi-stratigraphic division. It is also a good base for carrying out geological and scientific education, which is a rare “stratigraphic laboratory”. It has been determined as “standard profile of Huabei Cambrian” for a long time, and listed as geonomy text-book. It has important significance to carrying out effective protection countermeasures in geological trace.
