斜長斑巖
英文
plagiophyre-
The mafic dikes also formed by the partial melting of enriched mantle, include gabbro, diabase ( distributing mainly in luxi ) and lamprophyres ( camptovogesite, odinite and hornblende lamprophyres ) ( mainly in ludong ). for all the rocks, crustal contamination was absent when magma emplaced. 2
基性脈巖主要包括輝長巖、輝綠巖(主要分佈在魯西地區)和煌斑巖(以斜閃煌斑巖為主,同時含部分拉輝煌斑巖和角閃煌斑巖) (主要分佈在魯東地區) ,都為富集巖石圈地幔部分熔融的產物。The lithologies of intrusive rocks were re - determined, for example, the rock previously named as diorite in southern area was renamed as gabbro, and the dike rock distributed along nnw as spessartite which was related to formation of the zhulazaga gold deposit to some extent
對礦區各類侵入巖重新釐定了它們的巖性特徵,如礦區東南部原閃長巖重新確定為輝長巖,確定nnw向分佈的脈巖為閃斜煌斑巖,且認為後者和朱拉扎嗄金礦的形成有一定的關系。Through the study of the example of shaxi porphyry body in anhui province, the authors first figured out the storage time of plagioclase phenocrysts, then calculated the nucleation rate and growth rate of the crystals and, on such a basis, established the thermal model for cooling of the hypabyssal magmatic system
