- 柴北緣加里東造山帶中既產(chǎn)有VHMS型Cu_S礦床(如青龍灘礦床),也產(chǎn)有SEDEX型Pb_Zn礦床(如錫鐵山礦床),兩者的成礦地質(zhì)構造背景和形成年齡不相同。SEDEX Pb-Zn deposits such as the Xitieshan Pb-Zn deposit and VHMS Cu-S deposits such as the Qinglongtan Cu-S deposit occur in this Caledonian orogenic belt, but their geological settings and formation ages are different.

- 作者以連續的兩篇文章綜述了柴北緣地區的加里東造山帶中產(chǎn)出的兩類(lèi)不同的塊狀硫化物礦床,這就是噴流沉積(SEDEX)型Pb_Zn礦床和火山巖容礦的塊狀硫化物(VHMS)型Cu_S礦床。Two types of massive sulfide deposits occur in the Caledonian orogenic belt along the northern margin of Qaidam basin, i. e. sedimentary exhalative (SEDEX) Pb-Zn deposits such as the Xitieshan Pb-Zn deposit and volcanics-hosted sulfide (VHMS) Cu-S deposits like the Qinglongtan Cu-S deposit.

- 對產(chǎn)W-Sn、TR、Nb-Ta系列巖體能進(jìn)行二級判別,同時(shí)能判別殼源型花崗質(zhì)侵出巖的產(chǎn)礦性,以及區分加里東期交代花崗巖及混熔過(guò)渡型Cu花崗若。For the W-Sn, TR, Nb-Ta-forming granitoid series,a second-step discrimination can also be used. Besides, this linear equation is available for discriminating the ore-forming character of the crust-type granitic intrusion, and also for distinguishing the metasomatism-type granitoid of Caledonian age, and the Cu-forming granitoid of tran sitional mixmelting-type.
