  1. On the basis of the study on the petrology, trace element, and isotopic geochemistry, the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting. one is the basanite - alkaline basalt - olivine tholeiite magma series, which are generated by partial melting from spinel iherzolite ; the other is nephelinite magma - alkaline picritic basalt magma, which are generated by partial melting of the garnet iherzolite

    巖石化學、微量元素、同位素地球化學證據都表明，華北、華南地區的火山巖根據源巖和局部熔融程度的不同，可以分為兩個原生巖漿系列：一個是源巖為尖晶石二輝橄欖巖，隨著局部熔融程度的增加，形成的碧玄巖巖漿-堿性玄武巖巖漿-橄欖拉斑玄武巖巖漿；另一個是源巖為石榴石二輝橄欖巖，隨著局部熔融程度的增加形成的霞石巖巖漿-堿性苦橄玄武巖系列。
  2. Cu - ni sulfided mine complex locate in baimazai of jinping county is sub alkali iron - super iron, it ' s zoning is clear and it ' s ni - cu - co melting first and enrichment, its rare earth is rich in right lean light rare earth, but eu in olive rock is serious to be bad, gd - tb is tittles negative abnormity. above - mentioned show that the mineral is cone from mantle, and didn " t mix with crustal substance, and continent tholeiite magma turning into continent tholeiite emplacement after by surging

    金平白馬寨銅鎳硫化礦床雜巖體分帶明顯、屬亞堿性鐵質-超鐵質巖、具ni - cu - co三元素先熔離，后富集的規律、稀土配分為右傾斜輕稀土富集型，但橄欖巖銪虧損顯著， gd - tb微小負異常，顯示成礦物質來源地幔，與地殼物質無混染和大陸拉斑玄武巖漿上涌后變為大洋拉斑玄武巖漿侵位特點。
  3. Given their oib - type trace element pattern and depleted sr - nd isotop ic composition, the datong alkali basalts are interpreted to be generated within the asthenospheric mantle but at a shallow depth compared to the yangyuan alkali basalts. the datong tholeiitic basalts exhibit low snd values ( 1 - 4 ). their sr - pb and nd - pb isotopic correlations are consistent with a mixing between the depleted mantle and emi - like component

    大同地區第四紀時期同時產出堿性和拉斑玄武巖，堿性玄武巖也主要來自於軟流圈地幔，巖漿起源深度小於陽原樣品；拉斑玄武巖具有較低的nd （ nd = 1 - 4 ） ， pb - nd以及pb - sr同位素相關關系暗示其可能是dm和型富集地幔（ emi ）組分之間混合的結果，反映了軟流圈和巖石圈地幔之間的相互作用，巖漿起源較淺。
  4. Two ree distributed pattern, lree - depleted and flat, which display a specific character of typical mid - ocean ridge tholeiite, indicate that primary magma may be derived from near primary or a typical large ion lithophile element ( lile ) - depleted mantle

    巖石稀土元素配分模式可分為lree平坦型和lree虧損型兩類，指示了其原始巖漿起源於近原始或典型的大離子元素虧損型的地幔，為典型的大洋中脊拉斑玄武巖的特徵。
