The invention discloses a method for completely dehydroxylating hydrous minerals at normal temperature, the method comprises the following steps: putting the hydrous minerals to be treated into a sample cavity of a Capton plastic sealing pad, putting the sample cavity into a rotary diamond anvil cell device, gradually pressurizing, and rotating a diamond anvil cell; the technology provides unique technical support for simulating early-stage low-temperature high-pressure diving mechanical environments such as ocean-ocean diving, ocean-land diving and land-land diving, and is an effective tool for in-situ research on a high-pressure shear action dehydroxylation mechanism of hydrous minerals in the diving process of the cold plate. 本发明公开了一种常温下含水矿物完全脱羟基的方法，将待处理的含水矿物置于Capton塑料封垫的样品腔中，置于旋转式金刚石对顶砧装置中，逐步加压，并旋转金刚石压砧。该技术为模拟洋-洋俯冲、洋-陆俯冲和陆-陆俯冲等的早期低温高压俯冲力学环境提供独特技术支持，是原位研究冷板片俯冲过程中含水矿物高压剪切作用脱羟基机制的有效工具。
