2) ore-forming age
成矿年龄
1.
Researches on 47 ore-forming ages of uranium deposits and more than 200 ore lead isotopic samples in the North China Platform suggest that the oldest uranium deposits in China were all formed about(1800±100)Ma ago in spite of their different ore-forming envi.
通过多年来对这些地区所积累的47件晶质铀矿U-Pb同位素数据的整理处理,指出中国最古老铀矿床(矿点)尽管其成矿地域、成矿类型、成矿地质背景不同,但成矿年龄基本相同,在(1800±100)Ma左右成矿,铀成矿作用发生在早前寒武纪末吕梁造山期,而矿床可能主要在燕山运动期受到叠加改造。
3) metallogenic age
成矿年龄
1.

兰坪盆地金顶超大型铅锌矿床由于受样品和测年技术的制约,目前尚没有获得可靠的成矿年龄数据;矿区地质和矿床特征分析揭示成矿作用发生于沉积成岩和推覆体形成之后。
2.
The authors sum up the geological characteristics,ore-forming fluid features and metallogenic age of Liwu copper-rich deposit detailedly,and further discuss its genesis ba.
矿体呈似层状、透镜状,产状稳定,矿石矿物主要为黄铜矿、磁黄铁矿、闪锌矿等硫化物,总结该矿床的地质、成矿流体特征和成矿年龄,进一步探讨矿床的成因,对于该区的找矿工作具有指导和现实意义。
4) rock-and ore-forming ages
成岩成矿年龄
5) adult age
成年年龄
1.
The legal adult age in our country is 18.
我国法定成年年龄是18岁。
2.
The author discusses the definition and standard of adult,makes overall research on the relationship between behavior capacity and adult age,analyzes the necessity of enhancing adult age on the basis of our country\'s present situation,and finally puts forwards some advice on the adult system.
通过对成年含义及确定成年标准的论述,对行为能力与成年年龄之间的关系作了多方面的考察,并从理论上以及我国现阶段国情的基础上分析提高成年年龄的必要性,从而结合现行立法,提出有关成年制度的设想和建议。
6) age of ore deposit
矿床年龄
补充资料：地球间隔年龄
分子式：
CAS号：
性质：又称地球形成间隔年龄。在元素合成作用结束以后，从太阳星云到固体地球形成这一时间间隔。利用碘-氙法和钚-氙法可以计算出这一间隔年龄。目前得到的最佳值为100×106年。
