求翻译：在主量元素随SiO2含量变化的相关图（图4-6）上,TFe2O3、MgO随SiO2的升高而降低，指示了橄榄岩和斜方辉石的分离结晶作用,而CaO的降低则说明了单斜辉石的分离结晶作用，Eu异常的缺失说明斜长石对分离结晶过程的影响不大。是什么意思？

The major elements (Figure 4-6) with the sio2 content tfe2o3, mgo with sio2 increased lower indicates the peridotite and oblique Fang Hui stone fractional crystallization of the cao's lower then the clinopyroxene fractional crystallization of the eu 'unusual lack of plagioclase fractional crystalliz

In the main element SiO2 content changes with the associated graph (figure 4-6, and 2 O TFe MgO along with 3, 2 SiO increases, indicating the olive party rock and stone-fruit, the separation of the lower CaO is a single-crystalline role separation of the stone, Eu exception is the missing note of fe

In the host quantity element along with the SiO2 content change related chart (Figure 4-6) on, TFe2O3, MgO reduced along with the SiO2 ascension, has instructed the peridotite and the enstenite fractional crystallization, but CaO reduced explained the clinoenstenite fractional crystallization, the E

Change of major elements in SiO2 content (Figure 4-6), TFe2O3, MgO along with raising and lowering of the SiO2, indicating a separation and crystallization of peridotite and oblique Fang Huishi, CaO reduced description of the separation of clinopyroxenes crystallization, Eu anomaly missing descripti
