What is an Ore Deposit Model
什么是矿床模型

·It is a synthesis of available information on the deposit type, including the most informative and reliable characteristics recognized on a variety of scales.

矿床模型就是把某一矿床的各种有用的信息综合起来，包括不同尺度上识别出的最全面而可靠的特征。

·Ore deposit models change as our knowledge advances.

矿床模型随着我们所掌握知识的增加而改变。

Ore deposits are complex and involve many different characteristics

矿床是复杂多变的，涉及很多不同的要素特征:

·Tectonic setting  大地构造背景

·Host environment  赋存环境

·Host rocks  围岩

·Shape and form of orebody   矿体的形状和形式

·Textures of ore  矿石结构

·Mineralogy of ore   矿石的矿物学特征

·Chemistry of ore  矿石的化学特征

·Age of host rocks and ore  围岩和矿石的年龄

·Source and composition of fluids  流体的来源及成分

·Chemical and mineralogical zoning  化学和矿物学分带

·Hydrothermal alteration mineralogy and zoning热液蚀变的矿物学及分带

·Structural setting and controls  构造背景和控制条件

·Post-depositional modification (deformation, metamorphism, weathering)

成矿后的改变 (变形,变质,风化)

· Geophysical character of ore and host rocks (density, magnetism, chargeability, conductivity)

矿体和围岩的地球物理特点 （密度，磁性，荷电率，导电率）

Ore deposit models bring the key characteristics together in a brief and understandable way
