4 ree geochemistry of fluorite, siderite, quartz, magnetite, calcite in ores mainly controlled by ore - forming fluids, in contrasting to those of the metamorphic minerals which controlled by crystal structure. the ore - forming fluids of initial stage show larger lree / hree fractionation than that of later stage. a narrow range of 6 ~ 4s valus for early stage chalcopyrite ( - 0. 3 to 2. 8 ) suggested that s originated from the mantle and the 6 13c and 8 18o valus of siderite range from - 11. 17 to - 15. 37 % and from 8 ~ 9. 1, respectively, it indicates that the c and o of ore - forming fluids were derived from the magma or organogenous sediment

The results indicated that with the change of water and sand condition and the altitude of tongguan and the development of the industry and agriculture in recent decades, the water environment of wei river had changed largely, which were shown as follow : annual runoff and seasonal flood decreased sharply ; water stream of large discharge decreased and the range of runoff decreased greatly ; sediment load per year decreased generally, sediment concentration of water increased, and the sand silting up was serious ; water channel swung and shrank, and water regime deteriorated ; frequencies of big floods decreased obviously, and hyper concentrated flood increased obviously ; water levels of the same runoff rose universally, and the frequencies of the floods increased and aggravated ; water pollution was very serious
結果表明，近期隨著水沙條件、潼關高程等的變化及工農業的發展，渭河的水環境發生了巨大變化，表現在年水量及汛期水量銳減；大流量級水流出現次數減少，水量減少幅度大；年輸沙量總體減少，河水含沙量增大，泥沙淤積嚴重；河道向擺動型發展，河道萎縮，河勢惡化；大洪水發生的次數顯著減少，高含沙小洪水明顯增多；同流量洪水位普遍抬高，洪災發生次數增加，洪災加重；水質污染極為嚴重。 -

The features of these sequences arerbefore sequence i deposited during the rapid subsidence of the depression, the range of the sediment is limited. sequence ii is the first series of source and reservoir rocks of the depression. there are regional unconformity at the bottom of the sequence iii. the rock type are variety. this sequence is evaluated as good source rock, sequence iv is associated with the first section of duhongmu formation, thick mudstone at the bottom and the thick single sandston are the main rock type. this sequence are evaluated as good source rock and reservoir. sequence v associated with the second and the third section of duhongmu. which is mainly mudstone and can be regional capping rocks
層序對應于阿爾善組二段，為深色泥巖與砂礫巖不等厚互層，是本區的第一套烴源巖和儲集層，可以作為本區儲層。層序對應騰格爾組，此時凹陷擴張，沉積層底部具有區域性的沖刷面，巖性變化大，是較好的生油層。層序對應都紅木組一段，下部泥巖發育，單砂層較厚，是主要的生油層和儲層。 -
