| 中文摘要: |
| 叠层石主要是由原核生物周期性的生命活动所引起的矿物沉积和胶结作用形成的叠层状生物沉积构造，代表地球上最古老和最原始的微生物生态系统。天津市蓟州区北部山区中的叠层石保存着距今 18~8亿年间的古生物、古气候、古地理等极为珍贵的环境信息，这些叠层石的数量丰富，特征突出，在解决这个时代的地层划分、对比、环境的演变和生物进化等各个方面，都具有重要的实际意义。随着经济的逐步发展，天津市蓟州北部山区在进行建筑石料开采时，对叠层石造成了一定程度的破坏。本文在摸清叠层石在天津市蓟州北部山区的分布特征和类型的基础上，总结 2003年以来国家和地方对叠层石等地质遗迹的调查和保护建设工程，进一步提出可持续发展对策，助力生态文明建设和乡村振兴战略。 |
| 英文摘要: |
| Stromatolites are mainly stromatolite-like biosedimentary structures which were formed by mineral deposition and cementation caused by the periodic life activities of prokaryotes, representing the oldest and mostprimitive microbial ecosystem on the earth. The stromatolites in the northern area, Jizhou District, Tianjin, preservethe paleontology, paleoclimate, paleogeography and other extremely precious environmental information from 1800-800 million years ago, and the number of stromatolites is rich and the characteristics are prominent, which have im-portant practical significance in solving the stratigraphic division, contrast, environmental evolution and biologicalevolution of this era. With the economic development, the mining of building stones in the northern mountainousarea of Jizhou, Tianjin, destroyed some stromatolites. Based on the distribution characteristics and types of stromato-lites in the northern mountainous areas of Jizhou, Tianjin, this paper summarizes the national and local investigationand protection construction projects of stromatolites and other geological relics since 2003, and further puts forwardsustainable development countermeasures to help the construction of ecological civilization and rural revitalization. |
