摘要
在矿床研究与矿床勘查中,矿体形貌包涵有重要而丰富的成因信息。基于矿体形貌与成矿构造之间的成生联系,本文将矿体形貌划分为4种几何类型:一维矿体形貌、二维矿体形貌、三维矿体形貌及复维矿体形貌,并将矿体形貌划分为5种成因类型:构造型矿体形貌、流体型矿体形貌、构造-流体型矿体形貌、岩溶型矿体形貌及沉积型矿体形貌。提出了矿体力性、矿体力向、矿体力度、矿体韵度、矿体时空的概念,讨论了它们与矿体形貌之间的联系。举例分析如何根据矿体形貌、矿体力性、矿体力向、矿体力度、矿体韵度、矿体时空等参数,最大限度确定矿体的构造成因,客观评价矿床的经济价值,并进行有效的成矿预测。基于此,提出了矿体形貌学的概念,认为矿体形貌学是研究矿体形貌分类、演变、内部结构构造,以及矿体形貌间的空间结构、时间结构、力学成因的一门边缘科学,是矿床预测中一种新的思维方法。
There is important and abundant genetic information in orebody form deposit studies and exploration.Based on the genetic information between orebody morphologies and metallogenic structures,the orebody morphologies are classified into four geometric types： one-dimensional orebody morphology,two-dimensional orebody morphology,three-dimensional orebody morphology and composite-dimensional orebody morphology,and five genetic types： tecto-type orebody morphology,fluid-type orebody morphology,tecto-fluid type orebody morphology,karst-type orebody morphology and deposition-type orebody morphology.Some new concepts,such as orebody force feature,orebody force direction,orebody force intensity,orebody mineralizing intensity and orebody time-space,are proposed,and discussed.The examples are explained to determine ore genesis,to give an objective evaluation of economic value of deposits,and to develop effective metallogenic prognosis.The concept of orebody morphology is put forward.It is suggested that orebody morphology is the science for classification,evolution and inner structure construction of orebody morphologies,and spatial structure,time structure among orebody morphologies and their mechanism.It is a new thinking method of deposit prediction.
