位于东北龙岗火山区的四海龙湾玛珥湖沉积物保存有清晰的年纹层,为进行高精度的纹层年代学研究和高分辨率的古气候重建提供了良好的材料。
2.
The varved lake sediments are invaluable because it is possible to build independent, absolute and high-resolution varve chronology based on varve-counting.
年纹层发育的湖泊沉积物可以提供独立的、绝对定年的时间标尺,为重建高分辨率的区域古地磁场长期变化主曲线提供了难得的条件;基于长而连续的湖泊沉积物年纹层时间标尺建立的区域磁偏角和磁倾角长期变化参考曲线大大增强了岩芯对比和古地磁定年结果的精确性。
3.
Based on the independent, inherent and continuous calendar varve chronology, high resolution paleoenvironmental information can be obtained at annual or even seasonal scale.
文章总结了前人对湖泊沉积物年纹层类型的划分,并根据年纹层的形成过程和组分特征分为3个大类,即碎屑年纹层、生物成因年纹层(如硅藻年纹层等)和化学成因年纹层(如方解石年纹层、菱铁矿年纹层、黄铁矿年纹层、蒸发盐年纹层等)。

5cm间为36个年纹层,纹层计年的误差为4%~7%,年纹层厚度为1。
3) annual laminations of grain size
粒度年纹层
1.
Through coring a sample mud column without disturbing it in the lacuster of Angulinuo Lake, getting some thin sections from the core, and observing the sections under scanning electronic microscope, the researchers have discovered annual laminations of grain size that are made up of lacustrine deposits and eolian deposits, and the eolian deposits are transported by winter monsoon.
在安固里淖湖心区获取一未扰动沉积物样柱 ,分析发现了由冬季风搬运物与湖心沉积共同形成的粒度年纹层 ,建立了纹层年表 ,恢复了安固里淖湖区 85 0 7aB 。

补充资料：始建国二年规矩兽带纹镜
始建国二年规矩兽带纹镜 纪年镜叶，传世最早的是西汉居摄元年（公元6年）镜，1924年朝鲜平壤附近出土，现藏日本。始建国二年镜，较前者迟四年（公元10年），是国内现存最早的一面纪年镜。清同治年间，祥符周星诒季V宫福建同知时，收得于福州采铜局，遍征当时名人题跋，后赠其外孙冒广生收藏。直径15.8厘米。镜呈灰黑色（俗称水银古），素圆纽及纽座，围以七乳，四组草纹，内轮铭文“宜子孙”三字，外围双线，T、V形规矩，四大乳环以羽人神兽，外轮铭文篆书五十一字左行，外圈S形涡云纹带。铭文：“唯始建国二年新家尊，诏书数下大多恩，贾人事市，不躬啬田，更作辟雍治校官，五谷成熟天下安，有知之士得蒙恩，宜官秩，葆子子孙。”莽器传世不多，除量、衡等数件外，此镜是很重要的一件。经《古镜图录》、《小校经阁金文》和日本出版的《汉、三国、六朝纪年镜图说》著录。1956年由上海文管会收购入藏。
