Guided by theory and method of unit - superunit mapping in the granite area , study the lithology , lithochemistry , trace elements , and rare earth elements , er . of the wuzengsu gabbro body , and subdivide the body into four units 摘要借鉴花岗岩区单元超单元填图理论方法，通过对乌增苏辉长岩体岩石学、岩石化学、微量元素、稀土元素等特征的研究，将岩体划分为四个单元。
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 对矿区各类侵入岩重新厘定了它们的岩性特征，如矿区东南部原闪长岩重新确定为辉长岩，确定nnw向分布的脉岩为闪斜煌斑岩，且认为后者和朱拉扎嗄金矿的形成有一定的关系。
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 基性脉岩主要包括辉长岩、辉绿岩(主要分布在鲁西地区)和煌斑岩(以斜闪煌斑岩为主，同时含部分拉辉煌斑岩和角闪煌斑岩) (主要分布在鲁东地区) ，都为富集岩石圈地幔部分熔融的产物。
Geochronological , geochemical and sr - nd isotopic data are reported for the alkaline igneous rocks ( syenites and zhaibei aluminous a - type granite ) and chebu gabbro in southern jiangxi province . shrimp zircon u - pb dating results indicate that the quannan syenite , zhaibei a - type granite and chebu gabbro formed during the early yanshanian period 对赣南燕山早期的富碱火成岩(正长岩和寨背铝质a型花岗岩)和车步辉长岩进行了详细的年代学、元素和sr - nd地球化学研究。
The alkaline basalts in southern hunan are suggested to have formed by small degrees of decompression melting of the asthenosphere mantle during the initial extension . the transitional ( the chebu gabbro ) and tholeiitic basaltic magmas were generated by relatively larger degrees of partial melting of the mantle 在裂谷初期，软流圈地幔的小比例部分熔融形成碱性玄武岩(湘南) ，在裂谷拉张作用比较强、地幔部分熔融比例比较大时形成赣南和湘南的过渡型(车步辉长岩)及拉斑质玄武岩。
Electrical conductivities of quartz , olivine , dunite , iherzolite , pyroxenite , and megaaugite were measured by virtue of the new system ; whereas , the electrical conductivity of gabbro was measured by means of the old one . an interesting outgrowth of the present study is the measurement of the complex impedance of a series of quartz plates with different orientations 石英(人造水晶) 、橄榄石、纯橄榄岩、辉石岩、二辉橄榄岩、巨晶辉石的电导率测量是在新的测量系统下获得的，而辉长岩的电导率测量是基于lcr仪为测量仪器的测试系统下获得的。
Qimanyuter ophiolite melange crops out 1 - 3 km in width and extends ew - nee about 50 km , parallels to the kunlun mountains . qimanyuter ophiolite melange is composed mainly of serpentinite ( metapyrolite ) , peridotite , bedded gabbro , grbbro , diabase sheet and pillow - like and massif basalt as well . associated sedimentary rocks with this ophiolite melange include silicalite , dark gray silicalite and thin - bedded limestone 该混杂岩带所包含的主要岩性单位包括：蛇纹岩(变辉橄岩) 、橄榄辉石岩、层状辉长岩、辉长岩、辉绿岩席、枕状、块状、杏仁状玄武岩，与之共生的沉积岩为紫红色硅质岩、深灰色硅质岩、薄层灰岩等。
