随着地质工作的不断深入,摆在地质作工者面前的任务是,不仅要确定矿物和岩石的种类、分布和矿床的类型,而且要知道这些矿物、岩石和矿床是在什么样的条件下和怎样形成的.这就要求我们查清形成它们的物理化学条件.相图是研究各种物理化学条件下矿物相变化的一种重要方法,目前,愈来愈多的矿物、岩石和矿床学家正在用这种方法研究岩石和矿床的形成条件. 构筑相图的方法主要有三种.(1)实验方法:这是最基本的方法,但所需设备比较复杂,费用较高,控制条件要求严格,并且实验所需时间也
As geologic work continues to deepen, the task before geologists is not only to determine the type and distribution of minerals and rocks and the type of deposit, but also to know under what conditions do the minerals, rocks and deposits Which requires us to find out the physicochemical conditions that formed them.The phase diagram is an important method to study the phase change of minerals under various physicochemical conditions. At present, more and more minerals, rocks and mineral deposits Home is using this method to study rock and deposit formation conditions.There are mainly three ways to build phase diagram: (1) experimental method: This is the most basic method, but the required equipment is more complex, the cost is higher, the control conditions Strict, and the time required for the experiment also
