When O and radiogenic isotopic measurements are employed as tracers to evaluate magma-country rock interaction it is essential to provide evidence that open system processes have not perturbed the isotopic systematics.

用氧同位素和放射性同位素示踪岩浆和围岩相互作用时，必须在开放体系没有扰动同位素系统情况下进行。

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。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
