THE COMPARTMENTALIZATION OF MINERALS SEQUENCE OF MINERAL DEPOSITS IN SHAANXI PROVINCE

Based on systematical summarization, the major mineral deposits occurring in Shaanxi province have been firstly compartmentalized into 4 serial compositions of mineral deposits, including 22 serial types of mineral sequences, 42 mineral sequences and some sub sequences. The dominant mineral sequences of gold deposits in Shaanxi province include the gold and polymetallic mineral sequences that are related to the Yanshanian metamorphic magmatic hydrothermalism, the mineral sequences relevant to metamorphic hydrothermal liquid in the juncture of the Shang Dan Plates, alluvial pluvial placer gold sequences in present rivers, the mineral sequences relevant to hydrothermal filtration and the gold mineral sequences relevant to alkali carbonates in active orogenic belt; the major mineral sequences of silver deposits are the siderite silver polymetal sequences in flysch formation; the major mineral sequences of copper deposits are related with the iron copper deposits in the Proterozoic medium acid rocks; the iron copper gold tungsten fluorite mineral sequences relevant to medium acid granitoid of the Caledonian and Indo Sinian epoch; the copper zinc deposits relevant to marine medium basic volcanic rocks; the copper zinc pyrite mineral sequences relevant to the Precambrian metamorphosed volcanic rocks; the major mineral sequences of molybdenum deposits appear as molybdenum iron copper deposits relevant to medium acid small rock masses (phorphyry); the mineral sequences of lead zinc deposits were related to submarine hydrothermal eruption sedimentation, to hydrothermal filftration and submarine eruption and sedimentation hydrothermal reformation; the mineral sequences of mercury antimony deposits were related to hydrothermal filtration; the mineral sequences of barite deposits are vanadium molybdenum barite phosphorite pyrite stone coal deposits related to the Cambrian Ordovician systems and the barite uranium stone coal deposits in the Lower Silurian System; the major mineral sequences of coal deposits are the coal oil shale deposits in large scale inner continental basins and the coal aluminum pyrite clayrock kaolinite deposits relevant to continental oceanic alternating sediments; the major mineral sequences of rock salt deposits occur in the rock salt (soda) deposits in the Ordovician System.
