中文拼音 [xiádànhuà]
霞石化
英文
nephelinization-
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。By now in gansu province, there are more than 80 locations of danxia landforms, some of which have become well - known scenic tourism areas such as mount maiji, mount lianfeng, mount jifeng and so on. gansu province has had many cultural resources, which endows danxia landforms with rich cultural connotations.

文摘:介紹了中國霞石正長巖的分佈、產出的大地構造環境、巖體的巖石組合、巖石的地球化學和造巖礦物組合特徵。Analysis f k and na in nepheline were curried out with higher precision and repeatability by means of adding fluohydric acid during sample melting to remove sio2, adjusting the ratio of k and na in the solution to reduce the mutual interference of the two elements, and adding cesium chloride to eliminate ionization interference
摘要本方法用於測定霞石中的鉀、鈉，主要通過在溶樣時加入氫氟酸除去二氧化矽，調整溶液中鉀、鈉的含量，消除互相之間的干擾，加入氯化銫消除電離因素的干擾，提高了分析結果的準確性和重現性，使測定結果更接近化學分析值。Analysis of k and na in nepheline were curried out with higher precision and repeatability by means of adding fluohydric acid during sample melting to remove sio2, adjusting the ratio of k and na in the solution to reduce the mutual interference of the two elements, and adding cesium chloride to eliminate ionization interference
