Based on the study of correlativity of ol - opx - cpx contents in north china and south china , it shows that some peridotite xenoliths from hannuoba , pingquan , nvshan , puning , qiongbei , and niutoushan area may represent the older mantle material compositions , and some peridotite xenolith from ximeng , penglai , linqu , quzhou , mingxi , and liuhe area may represent the younger mantle material compositions 通過對華北、華南兩區橄欖巖包體中的o1與opx及cpx的相關關系的分析研究認為，華北漢諾壩和平泉地區，以及華南女山、普寧、瓊北、牛頭山等地區的部分橄欖巖包體，代表了老地幔；錫盟、蓬萊、臨朐及衢州、明溪、六合等地區的部分橄欖巖包體代表了較新地幔。

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 該混雜巖帶所包含的主要巖性單位包括：蛇紋巖(變輝橄巖) 、橄欖輝石巖、層狀輝長巖、輝長巖、輝綠巖席、枕狀、塊狀、杏仁狀玄武巖，與之共生的沉積巖為紫紅色硅質巖、深灰色硅質巖、薄層灰巖等。

Especially interesting is the serpentinous peridotite in this belt occurred as lense blocks of various sizes , and superimposed with other geological masses with faults , and in combine to constitute the mixture . system in the belt . five tectonic stage can be discerned in this area : ( 1 ) south - north ward overthrust ; ( 2 ) sinistral strike - slip ( 3 ) dextral strike - slip ( 4 ) south - north ward overthrust ( 5 ) northeast , northwest late stage fault 本區上述的結構構造特征先后經歷了五期構造作用，依次為： ( 1 )南北向逆沖推覆； ( 2 )左行走滑； ( 3 )右行走滑； ( 4 )南北向擠壓推覆； ( 5 )北東向、北西向晚期斷裂；

According to the sr - nd isotopic characteristics of peridotite xenoliths and their host basalts , it indicates that xenoliths in hannuoba , puning area may represent source area of the host basalt because of the xenoliths and host rocks being in the same plot ; however , the xenoliths is not directly related to their host rocks of the others area for the xenoliths plot out of the range of their host basaltic rocks . thermal dynamics calculation shows that the peridotite xenoliths are formed in the condition of pressure of 9 . 45 - 25kb and temperature of 945 - 1281 橄欖巖包體及其寄主玄武巖的sr - nd同位素研究表明，漢諾壩與普寧地區部分包體樣品投點落在其寄主玄武巖nd和sr同位素的分布范圍內，表明橄欖巖包體代表了寄主玄武巖的源區，而其它大部分地區的包體其寄主玄武巖范圍之外，表明寄主玄武巖和橄欖巖包體無成因聯系，橄欖巖包體只是偶然包體。

Based on the studies of petrotexture , structural deformation and the relevant metamorphism , this paper indicates that this peridotite massif is the product of ultramafic magma cumulated at the crust - mantle transtion zone and has undergone the early stage of plastic deformation under the condition of granulite facies （ 800 ） and late ductile shearing at amphibolite and greenschist facies in relevance to uplifting 本文通過巖體的結構、構造變形及相應的變質作用研究，提出了該橄欖巖體是由超基性巖漿在殼幔過渡帶結晶而成，并經歷了與圍巖一致的麻粒巖相（ 800 ）條件下的早期塑性變形以及角閃巖相和綠片巖相退化變質條件下與逆沖上升有關的韌性剪切變形。

Under the cooperation of lifts and mantle fluids , the melting point of mantle peridotite fell , and then , extensive melting took place in the enriched mantle , which resulted in the appearance of abundant mafic dikes , ultramafic dikes and contemporaneous volcanic rocks in shandong province 綜合堿性超基性脈巖和已知的青山組的火山巖、基性脈巖年齡數據，認為山東地區中生代地殼拉張至少存在四次：即約80ma 、 100ma 、 120ma和140ma 。

These studies , therefore , suggest that the songsugou peridotite is not a tectonic massif of the upper mantle but a ultramafic magmatic rock body crystallized in deep crust and tectonically emplaced in the upper crust 從而證明了松樹溝橄欖巖體并不是上地幔巖石的殘片，而是由巖漿在深部地殼環境下結晶而成并以固態構造侵位于地殼的上部。

The ophiolite massifs are composed of mantle peridotite that is mainly harzburgite and dunite , and lacked of crust magmatite within the typical ophiolite suite 摘要該蛇綠巖帶的巖體由地幔橄欖巖組成，主要巖石類型是方輝橄欖巖和純橄欖巖，缺少典型蛇綠巖剖面中的洋殼單元。

The songsugou peridotite in shangnan , shaanxi province is an important but petrogenetically debated ultramafic massif in the qinling orogenic belt 陜西商南縣松樹溝橄欖巖體是秦嶺造山帶中具重要意義和爭議較大的巖體。
