解釋
火山煙流-
High - mg volcanic rocks approach the primitive mantle compositions, and their magmatic source is close to the composition of bse, derives from the lower mantle and formed by this type - mantle rocks " fractional melting highly ( > 25 % ). high - mg volcanic magma, formed in the axis of the emei mantle plume, underwent the crystallization differentiation of olivines and some pyroxenes ; some olivines reflect fair cumulus crystallization
高鎂火山巖接近於原始巖漿的組成，巖漿源區與地球平均成分bse的成分特徵相近，起源深度為下地幔，為該地幔巖較高程度的部分熔融（ 25 ）而形成的。高鎂火山巖處于地幔柱的軸部，經歷了橄欖石及一定程度的輝石分異結晶，並且橄欖石顯示出一定的堆晶作用。 -
The most powerful plume in nature is volcanic plume, which is formed by ejection of mixture of pyroclasts and volcanic gases in to the air from volcanic vent
世界上中最壯現的羽流現象是由爆炸性火山噴發的各種火山氣體、細粒的火山噴發碎屑物所組成的火山噴發柱，也就是我們俗稱的火山蘑菇雲。 -
The strength and type of volcanic plume is not only influenced by the physical character of pyroclasts and volcanic gases but also influenced by the environmental conditions and forces
火山噴發柱的強弱和類型受火山噴發柱流體物理性質、動力狀況力和周圍環境條件的制約。 -
Beginning with the minerogenetic theory of mantle plume, the basic geological conditions of this type deposit can be summarized through studying typical copper - nickel sulfide deposits which have close bearing on continental flood basalt. in contrast with high - mg volcanic magmatic activity, it can be found that some intrusive rock bodies have ni - minerogenetic geology condiction. xilaping rocks in binchuan - chenghai region has some basic geological condiction and reflects some extent minerogenetic. all these testify this region has very larger potentiality of finding copper - nickel sulfide deposits
通過對研究區內與峨眉山玄武巖活動有關的高鎂火山巖進行研究對比，發現區內與峨眉山玄武巖同期形成某些侵入巖體具有成鎳礦（化）的地質條件。研究區內的昔臘坪巖體除了具有這些基本地質條件外，還顯示不同程度的礦化，說明該地區作為尋找鎳礦的靶區是有很大的潛力。
