For the multifractal method, there is still no standard being set up to determine the threshold anomaly of metallogenic prognosis by the soil elements. This paper presents a calculation method using the cumulative frequency of elemental contentsnumber of deposits. The anomaly area obtained by this method can well identify the most of known deposits. Meanwhile, by this method some blank abnormal areas which are worthwhile to do further anomaly inspection have been identified.

多维分形方法下土壤元素成矿预测的异常下限值确定尚无标准，文中采用元素含量矿床数目累积频率的计算方法，基于该方法提取的成矿异常区域较好地识别出了绝大多数已知矿床，同时识别出了值得作进一步异常查证的空白异常区域。

In the ores there exist a low-temperature mineral assemblage of arsenopyrite, stibnite, jamesonite, silver fahlerz,berthierite, and electrum, which is consistent with the measurement result of the ore temperature. It can be seen that one the outstanding features of the Sawaya''erdun gold deposit is low-temperature metallogenesis.

Based on the pressure curve experiment, the physical characteristic of ore-bearing rocks of the Luoba lead-zinc deposit in the Qinling Xicheng deposit field shows small porosity, low permeability and bad link ostiole in the ore-bearing rocks series. The feature indicates that the physical characteristic of ore bearing is unfavorable for forming the Luoba lead-zinc deposit.

采用压汞分析技术对秦岭多金属成矿带西成矿田洛坝铅锌矿床含矿层各岩系的物性特征进行了研究，结果表明含矿层各岩系物性特征具有孔隙度小、渗透率低、孔喉连通性差的特点，这一特征对洛坝大型矿床的形成是极为不利的。

The annual average temperature is 32.4～33.1℃ in the process of the formation of the suberustal, which is counted by oxyhydrogen isotope.

这类风化壳矿床成矿过程所涉及的主要问题是：风化环境及风化源岩。1 成矿古纬度山西铝土矿形成时的古纬度主要是通过对铝土矿或铝土岩的古地磁测试来认知的。

The remote sensing differential information processing technique, the X fluorescence survey of stream sediments and the subaerial base rock gama survey technique were jointly applied in the Puziwan gold deposit, Shanxi to study the gold metallogenic fluid field .

综合运用遥感微差信息处理技术、水系沉积物X荧光测量和地表基岩伽玛能谱测量方法研究了山西堡子湾金矿的成矿流体场，发现主要的矿化蚀变带呈NW向展布，与含矿的NEE向角砾岩带斜交，表明成矿后受到一定程度的改造。

In the North Ordos basin the sandstone-type uranium deposits developing in the system of sandstone beds of sedimentary facies of braided river course in Midde Jurassic Series,at the same time it happen some show of ore:the alteration zone of chloritization,bleaching decoloration and carbouation of epigenetic alteration,which show of ore are immediate and indirect for uranium mineralizing process.

摘 要：发育于内蒙古鄂尔多斯盆地北部中侏罗统直罗组辫状河相杂砂岩体内的砂岩型铀矿，有一系列较为特殊的与放射性铀成矿有直接或间接关系的成矿地质现象：绿色化蚀变带、漂白退色化带、二次胶结钙化砂岩团块及钙化砂岩断续层与&钙化木&后生蚀变现象；在与铀矿化和与油气的关系认识上存在一定分歧。

Based on sum-up and epurate from the first- and second-round national mineral assessment, new developing in minerogenetic series theory, minerogenetic dynamic theory and multi-information prognosis theory have been used to support and improve the methods for this round national resources strategy planning and prospecting. Working flow scheme and requests have been described in this paper.

通过对中国以往一轮、二轮区划预测方法、全国矿产资源总量预测方法及国外最新预测方法的分析和总结，结合近年来预测理论的新发展，确定了全国重要矿产总量预测的理论基础是成矿系列理论、现代成矿动力学理论和综合信息矿产预测理论，采用的预测思路是矿床模型综合地质信息预测方法。

The lead-zinc-silver mineralization zone at the north side of the Gangdise porphyry copper belt is an important component part of the Gangdise metallogenic belt and has great ore potential.

位于冈底斯斑岩铜矿带北侧的铅锌银矿化带是冈底斯成矿带的重要组成部分，具有巨大的成矿潜力。

The thermoelectricity of pyrite shows certain regularities of evolution in both time and space. From early to later stages of gold mineralization, the frequency of P type of pyrite and their thermoelectricity decreased gradually.

2黄铁矿的热电性在时间域上的演化具有一定规律性，从早期成矿阶段到主成矿阶段，P型的出现频率逐渐降低或热电系数值逐渐减小。

Temperature of gold mineralisation came from higher temperature (310～390℃)to middle temperature (200～290℃) early late-stage of mineralisation.

金矿的开始成矿于温度较高(310～390℃)的中阶段，并可能延续至中温(200～290℃)的成矿晚阶段早期。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
