1) Precambrian to Jurassic
前寒武纪至侏罗纪
1.
For example, it has been ascertained that the Precambrian to Jurassic Jilonggou stratigraphic section is another very important section that may completely correlate with the classical Nyalam-Zham section; the characteristics of the zonation of the Yarlung Zangbo suture zone have been further .
如:查明吉隆沟前寒武纪至侏罗纪地层剖面完全可与经典的聂拉木-樟木剖面对比,是喜马拉雅地区又一极为重要的剖面;进一步确定了雅鲁藏布江结合带具有分带特征,并划分出南、北2个不同时期的蛇绿混杂岩带;在扎东、穷果等地发现多处古人类活动遗迹。
2) pre-Jurassic
前侏罗纪
1.
Based on the compilation of stratigraphic isopach maps of the interval 10 of Yan'an and Fuxian formations and the top surface structure contour map of the Yanchang Formation,the pre-Jurassic palaeogeomorphic framework was d.
通过对下侏罗统延安组延10油层组和富县组地层等厚图及延长组顶面起伏图的编绘,基本恢复了前侏罗纪古地貌形态,并将其划分为河谷、斜坡、阶地、高地、平原和潜丘6种古地貌单元。
2.
The palaeogeomorphic form of the pre-Jurassic was reconstructed by the method of mold.
应用印模法恢复了鄂尔多斯盆地前侏罗纪古地貌形态。

前寒武纪
1.
Distribution, Types and Characteristics of the Precambrian Lead-Zinc Deposits in Eastern China;
中国东部前寒武纪铅锌矿床的分布及类型特征
2.
Hydrothermal Sedimentary Characteristics of the Precambrian Baritic Rock, Mianning, Sichuan Province;
四川冕宁前寒武纪重晶石岩的热水沉积特征及其矿床成因意义
3.
Fe isotope characteristics of early Precambrian pyrite deposits and their geological significance:examples from Shandong and Hebei Provinces;
早前寒武纪硫铁矿矿床Fe同位素特征及其地质意义——以山东石河庄和河北大川为例
4) Pre-cambrian
[英][pri:'kæmbriən] [美][pri'kæmbrɪən]
前寒武纪
1.
The authors discuss some major geological issues in Pre-Cambrian and Mesozoic ear in the South -East China in the light of recent geological mapping and re-expound the geological texture of Mesozoic ear in the South-East China.
作者根据近期一系列地质编图所取得的认识,就中国东南部前寒武纪和中生代地质的一些主要问题进行了讨论。
2.
Therefore,the Re-Os age of molybdenite in the Lüliang period not only provides evidence for existence of the Pre-Cambrian metallogenic period,but also shows the prospecting direction to find molybdenum deposits and the metamorphic porphyry-type copper-molybdenum ore in this area.
因此,吕梁期辉钼矿Re-Os年龄的获得,一方面证实了前寒武纪成矿期的存在,另一方面也为该地区寻找钼矿及变斑岩型铜钼矿指出了找矿方向。
3.
The regional ore-forming process was closely related to the Pre-Cambrian crystalline basement.
笔者认为,区域内铅锌(银)成矿与前寒武纪基底变质岩关系密切,矿体产于特定的地层层位和岩性建造(大理岩、含碳碎屑岩)内,并受一定构造部位的控制,华力西期岩浆活动对成矿具有改造变富作用,矿床成因类型属沉积变质-热液改造型层控矿床。
5) pre-Late Jurassic
晚侏罗纪前
6) Precambrian-Cambrian
前寒武-寒武纪

酒力醺然入四支，华胥税驾不应迟。
残年已觉衰难强，万事无如睡不知。
幸有琴书供枕藉，安能冠带更支持。
红炉过尽灰如雪，独守青灯坐画诗。
