中文摘要:矿产预测类型是以“矿床式”为基础,从预测的角度对矿产资源的一种分类,是沟通成矿规律与成矿预测方法的桥梁。文章在《重要矿产预测类型划分方案》所划分8大类和15个亚类的基础上,根据新的勘查和研究成果,结合金成矿条件,对中国6大行政区域的金矿预测类型进行补充和调整,并以预测区容矿建造为依据,从时间全位的视角将中国金矿预测类型划分出80个矿床式。文章认为以“全位成矿”理念为指导,以“矿床式”为基本单位的金矿成矿预测分类方案,能够推动找矿思路从“由果及果”转变为“由因推果”。金矿预测过程中通过紧抓“深、浅、远、近”4个条件,即成矿物质的初始来源深、成矿岩体就位浅、流体运移距离远、风化剥蚀搬运近,有助于开拓找矿思路。在特定区域开展中大比例尺金矿的成矿预测时,既可以根据已知矿床的矿床式开展就矿找矿,也可以根据成矿条件结合相邻地区已知金矿的成矿规律来发现新的矿床。 |

Abstract:Mineral prediction type is a kind of mineral resources classification from the perspective of prediction, which is based on the "deposit model", and it is a bridge between the metallogenic regularity and the methods of metallogenic prediction. This paper divides gold deposit prediction types into 80 deposit models by gold metallogenic conditions in 6 administrative regions of China from the view of holistic time, they are according to the lately achievement of prospecting and research, and base on the 8 categories and 15 subcategories in The Classification Scheme for Prediction Types of Major Mineral Resource. Taking the "deposit model" as basic unit, the classification scheme of gold mineralization prediction could convert the prospecting thought from "from the effect to the effect" to "from the cause to the effect", under the guidance of "holistic mineralization". It is helpful to expand the prospecting thinking by the following four conditions of "deep, shallow, far and near" in the process of gold ore prediction, that the initial source of ore-forming materials is from deep earth, the emplacement of ore-forming magma-tic rocks is shallow, the distance of fluid migration is far, and the transport distance of the weathering and denudation is near. It is possible to conduct on-site ore exploration based on the known deposit types, and to discover new deposits based on the mineralization conditions and the mineralization patterns of knowned gold deposits in adjacent areas, when conducting mineralization prediction for medium to large scale gold deposits in specific regions. |
