中文摘要：

模拟天然黄铁矿形成条件和基本过程，利用真空管式炉实验设备，通过热硫化法在250-410℃反应，实验考察不同温度条件下黄铁矿的结晶生长情况。运用扫描电镜、X射线粉晶衍射分析等手段，对实验产物形貌、物相结构特点等进行测试分析。结果表明：250-410℃时均可形成黄铁矿，但250-280℃时黄铁矿结晶程度较差；310～340℃时，可生长出部分晶面；360℃时黄铁矿生长成较为完好的晶体；380℃时黄铁矿结晶成立方体、八面体等自形晶；410℃时可形成结晶好、成分单一的黄铁矿。

英文摘要：

Natural conditions and formation process for pyrite were simulated. A laboratory vacuum tube furnace heater was used through the thermal curing process between 250℃ and 410℃. Responses were captured from the experimental study at different temperatures under the conditions of pyrite crystallization growth. Using the methods such as scanning electron microscope and X-ray diffraction analysis, the authors analyzed the pyrite in crystal form and structure. The results show that it is formed between 250℃ and 410℃, but it is low in degree of crystallization between 250℃ and 280℃. The partial crystal faces begin to grow between 310℃ and 340℃, and better crystal planes occur at 360℃. It has euhedral crystals that appear as cubes and octahedrons at 380℃. When it is 410℃, the pyrite crystallizes completely with a single composition.
