摘要
系统介绍了地气流的特征与组成。国内外大量的野外与室内研究成果证明了地气流的普存性。在正常的条件下，与矿化有关的金属微粒以某种方式随气相从地壳深部迁移到地表。这种元素迁移机制是对传统的地球化学迁移机制的补充与完善，并成为发展隐伏区地球化学找矿方法（如地气法、偏提取技术和元素分子形式法）的理论基础。
The characteristics and composition of the geogas streaming are discussed.The experiment in the laboratory and field observation home and abroad show that the geogas exists in everywhere.In the normal condition,metal particulate which is related to mineralization can be transported by the gas in certain way from the depth to the surface.This new mechanism is complementary and perfect to the theory of element geochemical migration and becomes the basis to develop the new geochemical methods,such as geogas ,partial extraction and molecular form of element(MFE)for the buried deposits.
