查询词典 ultrabasic

Due to very Complex geological structure in metallic ore areas, seismic method in base-ore metal exploration is a complicated question and this paper discusses the experiment and application effects of detecting hidden ultrabasic body and ore control structure with seismic method in deep coverage area combined with the experiment of jinchang Copper-Nickel polymetallic Deposit in Gansu province.

The authors believe that the diversification of rock zonation and lithology of these high pressure rocks can be attributed to the metasomatism that took place between deep melt and ultrabasic rocks in the subduction zone, and thus propose a hypothesis of subduction melt metasomatism to explain jadeite formation.

笔者认为俯冲带中形成的深部熔体与超基性岩之间的交代变质是导致岩石分带和岩性多样化的根本原因，提出了俯冲带熔体交代成因说，认为俯冲带、深部流体和超基性岩体是形成翡翠及其过渡品种的3个必要条件，并因此指出在人工合成过程中引入流体相很可能是降低实验条件的苛刻程度、从而合成出真正具有商业意义的翡翠的途径。

The regions which good quality jadeites should be determined by the four constraints as fellows: 1. In the subduction or collision zone; 2. In the ultrabasic rock bodies especia1ly in duniue bodies; 3. HP～UHP metamorphism zone; 4. Long duration deformation and metamorphism after rock forming.

优质翡翠的成矿预测与找矿靶区的确定应是符合以下四个条件的地区，即：a俯冲带或碰撞带内；b超基性岩体主要是纯榄橄岩体内；c高压与超高压区；d后期发生过长期的动力变质变形作用。

The ophiolite hosted in Danzhou Group of Proterozoic Erathem is not broken oceanic crust induced by tectonic intrusion but the result of lensoid type deformation partitioning of early basic and ultrabasic sheet in Longsheng, Guangxi.

广西龙胜地区的蛇绿岩并非是构造侵位于元古界丹洲群中的异地洋壳碎片，而是早期岩浆侵位的基性超基性岩席在原地遭受变形分解作用的透镜体型产物。

The shapes, occurences, rock types, mineral components and Petrochemical components of three ultrabasic rock groups all have different characteristics and show certain regularities. K-Ar and Sin-Nd iso...

各岩群的形态、产状、岩石类型、矿物成份、化学成份各有特点，表现出一定的规律性。K－Ar及Sm－Nd同位素年龄表明，这些超基性告形成于中元古宙、海西期及印支期。

The Ni orebodies occur in the laterite weathering crust of the upper part of ultrabasic rocks,which are controlled evidently by landform and belong to the oxidizing deposit of Ni silicate of laterite type in genesis.

镍矿体产于超基性岩上部的红土风化壳中，受地形控制明显，成因类型为红土型硅酸镍氧化矿，以褐铁矿型和腐岩型为主，矿石质量和可利用性均较好。

The two volcanic materials are similar but are also different ①the partition mode of rare-earth element is similar to that of the basalt.②the increase content of the rare-earth element content in transitional layer shows that it enrichs in this segment due to the volcano events. Moreover, the comparability of the partition mode shows that the volcano-genic materials and the basalt are of the same source.③low Eu anomaly different from the high Eu anomaly of medium-acidic tuff in Meishan section, that show that their formation is different④there are plentiful basalt detritus.⑤there are enrichment of the Ti element.⑥the lower content of siderophile element of Ni and Co, especially in the transitional layer, show that there were not extraterrestrial events and big scale basic or ultrabasic volcano eruption events in this area. These characteristics show that the sedimentary source of Xuanwei Formation and Kayitou Formation is basalt.

1稀土元素配分模式与玄武岩类似；(2)稀土元素含量在异常层的增加反映了火山事件导致了它在该段地层中的富集，而配分模式的相似性反映了火山物质来源与玄武岩具有同源性；(3)低"Eu"异常区别于煤山剖面的中酸性凝灰岩高"Eu"异常模式，说明界线粘土岩成因也不同于煤山剖面的界线粘土；(4)大量的玄武岩岩屑；(5)Ti元素的富集；(6)亲铁元素Ni和Co含量较低，特别是在界线异常层含量降低，表明本区在界线处可能并不存在地外事件和大规模基性、超基性火山喷发事件，这些特征反映本区宣威组和卡以头组物质来源主要为玄武岩。
