Large numbers of natural gas inclusions were found in the calcite vein filled in the structure joint and the fractures in the area of Triassic outcrop near the south margin of Mizi big natural gas field in the Eastern Ordos Basin.

The characteristics of stable isotopes and gas-liquid inclusions of the Shanmen Ag deposit,Jilin Province;

From fluid inclusion study of quartz vein,the equality temperature is 200 ℃～300 ℃,which indicates that Xigou ore deposit belongs to mesotherm hydrothermal deposit.

The experiments show the technique, which doesn t affect the searching of the fluid inclusions in ore, is suited to analyze the compositions of fluid inclusions, such as H2O, CH4,N2, CO2 and so on.

The study of petroleum inclusions,which has been made great progress in last 20 years,has played very important role in the evaluation of potential petroleum system.

Studies of petroleum inclusion properties are systemic and require combination of various methods,such as microscope fluorescence,Laser Raman Spectroscopy,quantitative grain fluorescence and group inclusion composition analyses.

Shuangdong anticline is a destructed paleo-oil structure,the widely distributed oil seeps,asphalts and petroleum inclusions in limestones of Tieling Formation indicated extensive petroleum migration here during the geological history.
