查询词典 radiogenic

Modified/Improved Rift heat flow modeling to account for radiogenic heat component loss during rifting. The traditional models over-predict heat flow and maturity in such basins.

改进的裂谷盆地热模式，可考虑裂谷过程中岩石圈厚度减薄引起的放射性生热的的损失，传统的模式中预测的热流和有机成熟度过高。

Each document about the individual meteorites contains all existing information such as petrography, whole rock and mineral chemistry, radiogenic, cosmogenic and stable isotope data and weathering.

该站点详细的介绍了火星陨石及其各自的具体特点，这些以PDF格式保存的档案文件包含了岩石记述学、岩石和矿物化学、射电数据、宇宙测年数据、稳定同位素数据等。

Terrestrial heat flow ; Crustal thickness ; Rock radiogenic heat ; Mantle heat flow.

大地热流；地壳厚度；岩石放射性生热；地慢热流

The radiogenic lead of coal fly ash is obviously higher than that of gasoline and diesel oil, which can serve as the discrimination criterion to distinguish the aerosol lead sources.

铅同位素含量数据表明成都市近地表大气尘的铅污染是复合污染源所致，其中，相对清洁区污染以建筑扬尘为主，中度污染区是汽车尾气和扬尘的叠加作用，重污染区是燃煤飞灰汽车尾气和工业污染源的综合表征。

This paper deals with the basic geothermal Characteristics and deep thermal settings in Yunnan Area by means of systematic borehole geotemperature logging, terrestrial heat flow measurements, radiogenic heat production determination and calculation of frictional heating in faults.

本文通过云南地区系统的钻孔地温测量、大地热流测试、放射性热源分布研究以及断层摩擦剪切生热的定量计算，阐明了云南地区地热基本特征与深部热背景。

Being very important, radiogenic components of helium (3He from 3H, 4He from U/Th)have been extensively used for groundwater dating.

中文摘要：放射性衰变产生的氦组分（3H衰变质产生3He，U/Th衰变产生4He）广泛地用水地下水测年。

The volcanic rocks and ores characterized by high concentrations of radiogenic lead indicate that the deposit formed on mature island-arc environment, and most of the ore lead was derived from the same environment as the associated volcanic rocks.

火山岩、矿石以富放射性成因铅为特征，反映成矿环境为成熟的岛弧环境，矿石铅与火山岩铅应属于同一来源。

SHRIMP analyses give 206Pb/238U ages ranging from 335～424 Ma for the zircons, showing a certain degree of radiogenic lead loss; so the age of 424±5 Ma reflects the minimum age of the metamorphic zircons.

SHRIMP分析表明，锆石206Pb/238U 年龄为335～424 Ma，有放射性成因铅丢失现象，因此可以推断424±5 Ma代表高压变质事件的最小年龄。

Low-temperature hydrothermal processes can mask evidence of high-temperature processes in the oxygen isotope system, and in radiogenic systems such as Re/Os and Pb where involved elements may be mobile under hydrothermal conditions, or host phases may close to exchange and uptake at different temperatures.

在氧同位素体系和放射性同位素体系(如Re/Os、Pb同位素体系)中，元素在热液条件下活动性强或主相没有发生同位素交换与吸收，都会导致低温热液过程掩盖高温过程。

The Wandashan massif, in which occurred HIMU-type OIBs with highly radiogenic Pb isotope compositions from the Raohe area, is a foreign terrane accreted to the CAOB.

其中在完达山地体的饶河地区出露了一套异常高Pb同位素比值的HIMU型洋岛玄武岩，代表了中生代的新增生外来地体。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.
