首先说一说,我为什么选这个题目。硫、磷、钾矿床是所(指“化学矿山地质研究所”)里研究的主要对象,在这里讨论一下硫、磷、钾矿床的关系是合适的。硫、磷、钾矿床的种类很多,这里主要讲其中一部分在时空分布上关系比较密切的硫、磷、钾沉积矿床。还要说明一下,我下面讲的这几个问题,都是比较大的问题,意见也不成熟,我个人认为是需要深入探讨的。一、硫、磷、钾沉积矿床的相互关系硫、磷、钾矿床,各自都有很多类型。比如说磷矿床,从内生的、外生的到变质的都有。这里要讲的主要是沉积的,以及原始是沉积的后来又受到交代、变质的。钾盐矿
First let me explain why I chose this topic. Sulfur, phosphorous and potassium deposits are the main objects of the study (referred to as “Institute of Chemical Geology and Mineral Geology”). It is appropriate here to discuss the relationship between the sulfur, phosphorous and potassium deposits. There are many types of sulfur, phosphorus and potassium deposits. Here, we mainly focus on the sulfur, phosphorus and potassium sedimentary deposits in which some of them are closely related in their temporal and spatial distribution. Let me also explain that the issues that I have mentioned below are relatively large problems and my opinions are not mature enough. I personally think that it is necessary to conduct an in-depth discussion. First, the sulfur, phosphorus and potassium deposits Relationship between sulfur, phosphorus and potassium deposits, each has many types. For example, phosphate deposits, from endogenous, exogenous to metamorphic have. The main thing to talk about here is sedimentary, as well as the original sediment was later metiscovered, metamorphic. Potash salt mine
