  In the process of fishing for concealed go ld-bearing breccia pipe in the sub volcanic complex in Qibaoshan area in Shandong Province, after detailed making tectonic-pet rogenic metallogenic texture model of the sub volcanic complex and fluid geneous-tectonic-metallogenic texture model o f the know n or e-bearing brecciapipe, pr edict ing and optimize looking for mineral deposits barn areas, we took advanced geochemistry and geophysical means to test and survey, and not only determined precise posit ion of the concealed ore-bearing brecciapipe, and still delineate and circle it s shape and size finally. This will raise prognostic precision of concealed mineral deposit,depress exploratory risk.

  Jiapigou Haigou gold mineralization zone is a structural magma active zone in eastern part of the northern margin of North China plate. The gold deposits were located in the turn or intersecting of large regional structures, gold ore bodies were located in brittle structures, occurred in the early stage structures or formed in Mesozoic era. Wall rocks of gold ore bodies formed in different era are diversified. The Argon age of gold bearing quartz vein is approximately 102 Ma. All of the above studies show that the location era of Jiapigou Haigou gold mineralization zone is Mesozoic.

  Mofang gou Gold Mine of Pingyi county,Shandong Province,is a type of impregnation gold deposit which emplaced in bedded limestone. The studies of ore-control factors of gold deposit show that the occurrences of gold bodies are controlled by the special layer( thick marl).The form of gold deposit related to activities of monopod phrymagma. The faults are ore-bearing hydrothemal channels of gold deposit on the basis of building up metallogenic model, we proposed the directions of the prospecting ore, these prognostic area had been confirmed to have gold ore bodies.

  Various kinds of liquid chromatography technology at present in application of analyles of surlphur bearing species, and the ionsex collusion and exchange of HS^- , S₂O₃^2-, SO₃^2-,S^2-x , etc, in LSSS and MLSSS under the conditions of diffterent media and different degree of acidity are studies, the application range of chromatography to reversionions is also studied.The polymethacrylare is used as the carrier for the first time on whiter quatemary ammonium functional group is induced as the ionexchange suppreesion column to measure sulturand it scompoundsuv spectrum with wavelength 210 nm is in use as the detector and the buffering agent NaHCO₂N a2CO 3 (pH= 10) the mobile phase. The methodis proved rap id and sensitive and with high selectivity at the same time, it is a separation and analyses technology of multicomponent system. It is realized that the above teehnique is an effective method for detecting multions bearing sulfurin aqueous solut ion s simultaneously.
