地球化学探矿是一門新的找矿方法。它是利用成矿元素及其伴生元素在矿床周围的岩石、疏松物質、水和植物中生成的分散晕和分散流来寻找矿床。它將成为綜合地質测量、普查和勘探工作不可缺乏的組成部份,并可以显著地提高这些工作的效果。兩年来我們通过实际工作的摸索,取得了一些初步經驗,也收到了一定的效果。但是由于对地球化学探矿的基本原理和应用条件不够了解,有的在技术措施及方法擺佈上还不够十分恰当,以致减低了它的实际效用,特別是还存在許多急待研究解决的技术問題。因此,共同学习了解化探的基本原理,掌握其应用条件,交流实际經驗,提高化探工作質量,乃是化探、地質及其他有关技术人员的共同任务。为此,请欧阳宗圻同志將地球化学探矿方法的基本理論,着重从岩石化学方法方面做比较系統的介紹。其內容大体包括:緒論,金属元素在地壳中的分佈,原生暈,机械分散暈,复杂暈,分散流,工作方法,水化学方法和生物地球化学方法等部份。对于一些理論性的問題及有关公式不做詳細的探討。对某些目前尚在爭論的学术問題只簡要提及,亦不做詳細論述。該文將由本刊自本期起連續刊載发表,大家有什么意見和要求,請及时函告本刊。
Geochemical prospecting is a new prospecting method. It is the use of mineralization elements and their associated elements in the rock around the deposit, loose material, water and plants generated scattered halo and dispersed flow to find the deposit. It will be an integral part of integrated geological surveying, census and exploration efforts and will significantly enhance the effectiveness of these efforts. In the past two years, we have made some preliminary experiences and obtained some results through our exploration of practical work. However, due to the lack of understanding of the basic principles and application conditions of geochemical prospecting, some of them are not sufficiently appropriate in technical measures and methods to reduce their actual utility. In particular, there are still many technical problems that need to be studied and solved urgently. Therefore, it is a common task of geochemical exploration, geology and other related technical personnel to learn together about the basic principles of geochemical exploration, to grasp its application conditions, to exchange practical experience and to improve the quality of geochemical exploration. For this reason, Comrade Ouyang Zongli requested that the basic theory of the geochemical prospecting method be focused on a more systematic introduction from the petrochemical method. The contents include: introduction, distribution of metal elements in the crust, primary halo, mechanical dispersion halo, complex halo, dispersive flow, working methods, hydrochemical methods and biogeochemical methods. For some theoretical issues and the formula does not do a detailed discussion. Some academic issues that are still under debate are briefly mentioned or discussed in detail. This article will be published in this issue from the issue of this issue, we have any comments and requests, please write to the timely publication.
