摘　　要：西成铅锌矿带作为我国重要矿产富集区,其成矿流体演化研究是理解成矿机制的关键。包裹体测温测压作为重要研究手段,然而传统设备与方法在操作流程、测量精度及范围上存在显著不足,制约了研究的深入开展。本研究采用模块化、组合式结构重新设计测温测压设备,优化温度和压力控制测量系统,并针对该矿带早期、中期、晚期矿化阶段进行精准试样采集。试验结果显示,测温测压设备温度精度为±0.5℃,压力精度高达±0.1MPa,远高于传统包裹体设备。As an important mineral enrichment area in China,the study of the evolution of ore-forming fluids in the Xicheng Lead-Zinc Ore Belt is the key to understanding the ore-forming mechanism.Inclusion thermometry and pressure measurement is an important research method.However,traditional equipment and methods have significant deficiencies in the operation process,measurement accuracy and range,which restricts the in-depth development of the research.In this study,the thermometry and pressure measurement equipment is redesigned with a modular and combined structure,and the temperature and pressure control and measurement systems are optimized.Precise sample collection is carried out for the early,middle and late mineralization stages of this ore belt.The test results show that the temperature accuracy of the thermometry and pressure measurement equipment is ±0.5℃,and the pressure accuracy is as high as ±0.1MPa,which is much higher than that of traditional inclusion equipment.
