Most of my career has been concerned with mineral resources in one form or another. This general subject was covered in a previous issue of Geochemical Perspectives (Arndt et al., 2017) so I will not repeat that overview treatment here. Instead I focus on my experience with a particular type of ore deposit, skarn deposits, and the unique geochemical laboratory that they represent. In simplest terms, a skarn deposit forms at the contact between an igneous intrusion and reactive wall rocks, commonly limestone. The strong temperature and compositional gradients between the hot magma and the cooler wall rocks...

3.矽胶矿床的成因与勘探

我的职业生涯大部分时间都以某种形式关注矿产资源。上一期《地球化学展望》（Arndt et al。，2017）涵盖了该一般主题，因此在此我不再赘述。相反，我专注于我对特定类型的矿床，矽卡岩矿床以及它们所代表的独特地球化学实验室的经验。用最简单的话说，矽卡岩沉积物形成在火成岩侵入体与反应性围岩（通常为石灰石）之间的接触处。热岩浆和较冷的围岩之间的强温度和成分梯度...
