普查阶段

矿区普查阶段比较系统地开展了万分之一岩石测量和原生晕找盲矿专题研究。

1 / 10,000 rock survey and blind ore prospecting with primary halos were carried out during reconnaissance stage .

由于草甸发育，颗粒物质迁移受到抑止，水系碎屑沉积物仅出现在2~3级水系。因此，在普查阶段可能会漏掉许多矿化信息；

Stream detrital sediments appear only in Grade 2 ~ 3 drainage , and hence much mineralization information might be lost at the reconnaissance stage ;

水地球化学方法一般适用于区域普查阶段。

The hydrogeochemical method is usually applicable to general survey of region .

对三个勘查区探矿权最佳评估方法提出建议，并主要就预查阶段、普查阶段的评估方法进行了总结。

The premium assessing method in these three exploration areas are recommended .

我国近海含油气盆地的勘探现状是油气普查阶段基本完成，但勘探程度差别较大。

The present situation of China offshore petroliferous basins is that oil gas reconnaissance has been basically accomplished , but there exists large differences in exploration degree .

在大面积地震勘探普查阶段缺少井下地球物理参数的条件下，应用地震波速度参数自身的基本规律及其岩性之间的内在联系来揭示包括砂泥岩百分含量在内的岩相分布是非常必要的。

In the course of seismic reconnaissance over a wide area where down-hole geophysical parameters have not been obtained , it is necessary to investigate lithofacies distribution including the percentage content of sand-shale from the basic rule of seismic velocity parameters and its inherent relationship with lithology .

在使用中，根据实际情况选用偶极-偶极或单极-偶极测量装置，其中偶极-偶极测量装置主要用于普查阶段，单极-偶极装置采用常规高密度电法的布极方式，主要用于详查阶段。

In practice , dipole-dipole or pole-dipole measurement devices are selected according to the specific conditions with the dipole-dipole device mainly used in reconnaissance and the pole-dipole device , which adopts the pole arrangement of the conventional high density electric method , and is mainly used in detailed investigation .

On Rational Classification of Reconnaissance Prospecting Stages for Solid Mineral Resources

近年来中国大陆矿产资源评价，逐渐由单一的地质经济评价、静态评价、普查勘探阶段评价向综合评价、动态评价、普查勘探和开发生产一体化评价转变。

In recent years , the focus of the assessment in China has been shifted from an economically static evaluation during exploration to the synthesized dynamic evaluation for exploration , development and markets as a whole .
