Through observation, description, slice identification of cores and chemical analysis of whole rock, it is determined that the central volcanic rocks of the eastern depression are classified as four major types, i. e. basalt, trachyte, tuff and cataclasite of sedimentary volcanic rocks, in which trachyte is of basic series and potassium rock type
通過巖心觀察、描述，巖心薄片鑒定，全巖化學分析等資料，確定東部凹陷中段火山巖巖石類型分為4大類：玄武巖、粗面巖、凝灰巖和沉火山碎屑巖類，其中粗面巖類屬于堿性系列、鉀巖類型。 -
These deposits, which can be obviously divided into basic and acid volcanic types, are present in the carboniferous bi - model volcanic series and occur along two horizons, i. e., the lower carboniferous mafic volcanic rock and the upper carboniferous felsic volcanic rock
這些礦床產在石炭系雙峰式火山巖系之內，沿著下石炭統基性火山巖和上石炭統酸性火山巖兩個層位產出，分別以玄武巖和流紋巖為容礦主巖，可以明顯地分成基性火山巖型和酸性火山巖型兩種類型。 -

大興安嶺北段早石炭世洋島型玄武巖的確立及成因意義 -
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。
