摘要
沉积岩流体包裹体具有个体小、数量少、气液比小的特点,测试过程中存在选样盲目性大,岩样切面和岩片厚度难以确定,岩片卸载和清洗方法不易操作,包裹体寻找和观察及其成分分析方法选择不当等诸多问题。文章提出了选样基本原则,制定了岩样切面和岩片厚度标准,改进了岩片卸载和清洗方法,丰富了包裹体观察技巧,并指出应依据包裹体的主矿物和成分选择测试方法,从而提高沉积岩流体包裹体测试效率和准确性。
<abstract>ny problems existed during testing, such as blindness in sampling, difficulty to determine cutting face of sample and slice thickness, difficulty to operate rock slice uninstalling and cleaning method, improper means of inclusion searching and observing and component analyzing due to small bulk, a few quantities and small gas-liquid ratio of the fluid inclusion in sedimentary rocks. Basic principle in sampling was put forward; the standards of cutting face of the sample and slice thickness were laid down; the methods of rock slice unloading and cleaning were improved; the means of observing inclusion was enriched ; and testing method selected according to the host mineral and its components of the inclusion was pointed out. All above raise the efficiency and accuracy of testing the fluid inclusion of sedimentary rocks.
