地质勘探

According to gold deposit minerogenetic process,there are many kinds of altered mineral associated silicolites,pyrites and multiple metal sulfides.

根据金矿床成矿过程中有各类蚀变体—硅化体、黄铁矿化和多金属硫化物伴生，针对测区存在覆盖层厚和高压线密集的客观环境，勘查金矿时选择CSAMT和TDIP单极-偶极测深进行构造及硫化物空间位置的圈定，在勘探区应用地球物理方法取得了较好地质效果。

In thispaper,the results obtained in the high resolution seismic explo ration and the economic benefits in recent years are introduced,with the emphasis on the resolvable geologicalproblems.

本文介绍了几年来采区地震勘探所取得的成果、所产生的经济效益，对所能解决的地质问题也作了重点介绍，并对所存在的问题及发展方向提出了看法。

Focusing on them, author has been investigating in open country and collecting, arraging and analyzing material for one and a half year. After having done the study on the new deep prediction, author presents new opinion on the base of part of precious geological opinion .1, Xiaohe deposit direction and turn are mainly controlled by the second structure rochet vault in the back of Bigsnown mountain. It is conjectured that the axis extent with the current direction to the 180# exploring line and turn to northwest-southeast direction. During the extension, the deposit body would extend from deep to low instead from low to deep. The turning place was level corresponding to the core of rocket vault.2, There are a chain of radiate blind regmagenesis controlled by the rocket vault.

笔者针对这两个问题，通过一年半的野外实地调查和室内资料收集整理分析，在进行了新的深部找矿研究工作之后，在认同前人部分地质观点(即小河～石门坎矿带的连续是存在的)的基础之上，又提出了新的观点，即： 1、小河矿床矿体的走向及转向位置主要受大雪山背斜的次级构造火箭山穹隆控制，推测其轴线将沿现在的走向，延伸至180#勘探线附近发生转向，轴线方向逐渐转为北西——南东方向，同时矿体从由浅至深逐渐变为由深至浅的延伸状态。

In seismic exploration, subsurface salt dome , as a high-velocity geologic body, brought about a series of problems to ordinary processing in time domain and interpretation, for example, false image of subsalt structure and abnormal stack velocity field.

在地震勘探中，地下盐丘作为一个高速地质体会给常规时间域处理和解释带来一系列的问题，如盐下构造的假象和叠加速度场异常等。

The magnetic methods have been successfully employed not only in the search for magnetite ore, but also in locating buried hills, geological faults, intrusions of igneous rocks, salt dome s associated with oil fields, concealed meteorites and buried pipe-lines.

磁法勘探不仅在找寻磁铁矿的方面卓有成效，而且在确定埋藏山丘，地质断裂，岩浆侵入体，储油的盐穹，埋藏的陨石以及埋没的地下管道等方面也很成功。

Carlin is where gold mining began for Newmont. In 1961, Newmont geologists began probing the high desert area around the Tuscarora Mountains in search of finely disseminated gold - gold that could be seen only in a microscope and, thus, had eluded earlier prospectors.

历史概述 Carlin是纽蒙特金矿的发源地。1961年，纽蒙特的地质人员开始在Tuscarora山四周的高沙漠地带寻找细颗粒浸染型金—一种极为细小，只有用显微镜才能看见的金子，所以以往的勘探人员都未能发现。1963年夏季通过钻孔和化验划定了一个 300万盎司的矿床，即使当时的金价每盎司只有35美元，该矿山也具有开采价值。

The foreign side is Westralian resources ventures Co. the domestic party is the brigade 407 of Hunan Geology ＆ Exploration Bureau. Established in July,05, to develop mining prospects in Guanzhuang,Yuanling county with an initial specific focus on gold.

外方为西澳大利亚资源有限公司，中方为湖南省地质矿产勘查开发局407队，我司成立于2005年7月，从事沅陵官庄地区的金矿资源勘探以及采矿、选矿，合作经营期限30年。

Cophasal axes on seismic sections play an important role in geologic stratification, fault interpretation, detection of cavities and other anomalous bodies in geophysical prospecting.

地球物理勘探中，地震剖面中的同相轴对地质分层、断层解释、有无形成空洞以及其它异常体的检测中作用重要。

It indicates that crevasse channel is a kind of very narrow and shallow short range small channel with a fixed path which is formed among wide ranged channels by the major channel after the avulsion crevasse in a fluvial and deltic sedimentary.

对以往研究较少，并在油田勘探阶段及开发初、中期地质研究中被遗漏或忽视的决口水道的成因、沉积特征与模式、空间分布及在油田开发中的意义进行了研究与探讨。

With the increasing of transmiting current and reducing of the minimal discriminable voltage, the influence of geological interference becomes more evident, so it is very necessary to introduce feasible mathematical methods to direct and inverse calculation of TEM, such as ANN, GA. Via an experiment on a known-profile in a copper mine, it is validated that the flexibility of the system and feasibility of the interpretation software.

数据采集软件、后期处理解释软件的编制及解释精度问题由于发送电流的加大和最小可测电压的提高，在加大了勘探深度的同时，地质噪声和各种效应的影响将更加明显，从而对解释软件也提出了更高的要求，传统的数据处理解释软件不能满足要求了，因此有必要引入成熟的数学方法：如神经网络等，增加一维、二维的解释精度与速度，并对于特殊三维体作正演计算。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
