The study on the origin of ore deposit, which is one aspect of the ore deposit study, studies the distribution regularity of mineralization and the geological factors of controlling the distribution. It is of great significance on improving the efficiency of prospecting. The origin of ore deposit, which causes the formation of ore deposits and forming process, is from the point of view to study the mineralization distribution. The main problem involved is that the space distribution of mineralization in the earth's crust within a certain area and the period of mineralization because of geological conditions change in the history of the earth's crust. Therefore, the deep mineral information collection, is very important. As a kind of prospecting method can provide the target element information directly, geogas prospecting method has unique advantages in obtaining deep mining information (Guo et al., 2007). Swedish scientists, Kristiansson and Malmqvist (1987), proposed the geogas prospecting method in the early 1980s. Since introduced into China, the method has made great development with Chinese geochemists’ unremitting, systematically researching, its prospecting effectiveness has been gradually recognized (Gao, 2006). This method has the following characteristics: (1) It can analyze metallogenic elements and associated elements, reflect the mineralization type in the deep directly and indicate the underground concealed structures. (2) It is influenced little by covering layer. (3) Its detecting depth is large. Trapping is an important part in geogas prospecting which affects the whole measurement process directly. The choice of capture agent is the key to improve the efficiency of capture. The liquid capture agent is used widely at present (Liu et al., 2003). The nitric acid and aqua regia solution is used as capture agent to compare aqua regia with nitric acid of the capture performance.
