Two REE distributed pattern, LREE-depleted and flat, which display a specific character of typical mid-ocean ridge tholeiite, indicate that primary magma may be derived from near primary or a typical large ion lithophile element-depleted mantle.

岩石稀土元素配分模式可分为LREE平坦型和LREE亏损型两类，指示了其原始岩浆起源于近原始或典型的大离子元素亏损型的地幔，为典型的大洋中脊拉斑玄武岩的特征。

The ultramafic rocks outcropped at the Altyn region are all harzburgites. Remant grains of primary minerals have melted residual texture and elastic deformation texture under high temperature and pressure. The whole-rock analyses show their low TiO〓 contents (0.01～0.04%), low Al, Ca and high MgO contents and wide Mg〓 range (89.35～95.57). Rare earth patterns have two types, namely tabacco pipe-shped and LREE-shaped, of which the former is often seen. The chondrite-nomalized Yb values of these analyses are all lower than 1. The spinels have low Ti and high Cr content and most spinels have Cr# higher than 60. All of the above characteristics show that the ultramafic rocks in the Altyn fault zone are components of metmorphic peridotites of ophiolite from depleted mantle source and most ophiolites from this zone belong to supra-subduction zone type ophiolite with a few mid-ocean ridge basalt type.

阿尔金露头区的超基性岩全为方辉橄榄岩，残余的新鲜矿物颗粒发育有熔融残余结构和高温高压下塑性变形结构，全岩分析显示样品TiO〓的含量低，为0.01～0.04％，具有低的Al和Ca，MgO含量高，Mg〓为89.35～95.57；稀土配分型式有两种，即烟斗型和LREE亏损型，前者占绝大多数，Yb球粒陨石标准化后的值全都小于1；尖晶石低Ti高Cr，大部分尖晶石的Cr〓大于60，上述特征说明阿尔金超基性岩是蛇绿岩的地幔橄榄岩成员，来自亏损的地幔源区，阿尔金蛇绿岩大多属于俯冲带之上型蛇绿岩，有少量的大洋中脊型蛇绿岩。

Gourd-shaped cavity was due to the wind tunnel cave open at both ends of the North-South pairs to wear again and hoisted mid-air, to the north,"Xianggui corridor", Nantong bridge between mountains and ocean ridge,"Gap Road", the air in this form.

洞形呈葫芦状，由于风洞两端洞体敞开又南北对穿且高悬半空，北接&湘桂走廊&，南通架桥岭与海洋山之间的&峡道&，空气在此形成强烈的对流，故名&风洞&，于是桂林人又把叠彩山称为&风洞山&。

Our results highlight that the mid-ocean ridge seismic belt, circum-pacific seismic belt and continental rift seismic belt all lie in the graben-horst structure and the movement of the horst might be closely related to the seismic activity.

研究发现，大洋中脊地震带、环太平洋地震带和大陆裂谷地震带均位于&两堑夹－垒&楔块系统中，其中一垒的活动，即倒楔的运动与地震带紧密相关。
