火山岩

This paper illustrates the potential of cosmogenic neon exposure age in studying the eruption., surface morphology, and erosion history of young volcanic rocks, which are difficult to date using other conventional methods,such as K-Ar or 40Ar/39Ar dating.

本论文阐述了宇宙中氖的暴露时间在火山爆发，表面形态和新形成的火山岩的侵蚀过程研究中的潜力。这些研究用常规的方法，如钾-氩或40氩/39氩测定年代较难进行。

They are almost cotemporary with the volcanic eruptions of Yixian Formation near Yi County in the south of Fuxin Basin.

与阜新盆地南部义县附近的义县组火山岩喷发的时代大致相当。

According to the latest researches, there is a set of MesozoicT_3-J_(1+2 palaeo-foreland basin deposits in the deep-seated Songliao Basin, which are composed of detrital rock, coal and volcanic rock.

根据最新的研究成果，松辽盆地深层存在一套早中生代(T3-J1+2)含煤和火山岩的古前陆盆地沉积。

Dioritic magmatic enclaves have been discovered in the subvolcanic ring dikes for the first time by this study. These enclaves have typical back-vein and quenched margin where there are a lot of needle-like apatites.

首次在相山北部次火山岩岩墙中发现的辉石闪长质岩浆包体，具有典型的反向脉及淬冷边，其淬冷边内含有大量的针状磷灰石。

Therefore , the quenched dioritic enclaves in subvolcanic granodiorite in Xiangshan were formed by the convection of the magma with different composition and temperature and by the heterogeneous mingling between them. These enclaves are genetically quenched enclaves.

因此，相山潜火山岩岩墙中的闪长质岩石包体是不同成分、不同温度的岩浆经对流及不均一岩浆混合作用而形成，在成因类型上属淬冷包体。

Dioritic enclaves were discovered by the authors in thesubvolcanic rock dike of the northern part of the large collapse volcanic basin in Xiangshan, Jiangxi Province. These enclaves have a typical back vein and a quenched margin,and contain a large number of acicular apatites.

在江西相山大型塌陷式火山盆地北部的潜火山岩岩墙中，笔者发现了闪长质的岩石包体，这种包体具典型的反向脉及淬冷边，且淬冷边内含有大量针状磷灰石。

This thesis has emphasized studies on forming mechanism of dioritic quenched enclaves in the subvolcanic dikes and cryptoexplosive breccia at depth of the Zoujiashan uranium deposit, systematically studied the diagenetic ages, geochemical characteristics and Nd, Sr, Pb and Lu-Hf isotopic compositions of the Xiangshan volcanicintrusive complex and mineralization at depth of the Xiangshan ore-field.

本文重点解剖了相山次火山岩中闪长质淬冷包体及邹家山富大铀矿床深部隐爆角砾岩的成因机制；系统研究了相山火山-侵入杂岩的成岩时代及其Nd、Sr、Pb和Lu-Hf同位素组成；同时还对相山火山-侵入杂岩的岩石地球化学特征及相山矿田深部的成矿作用进行了深入研究。

The epicontinental activities resulted in volcanic and magmatic arc granites.

三叠纪陆缘活动形成火山岩和岩浆弧花岗岩。

The epicontinental arc volcanics related to the Permo-Triassic activities suggest the subduction of the Jinshajiang oceanic crust,and the ocean-continent tectonic regime transformation and the northward accretion of continental crust.

与二叠纪和三叠纪活动陆缘有关的陆缘弧火山岩带反映金沙江洋壳发生消减、洋-陆构造体制转换和大陆地壳向北增生的过程。

Compared with those in other regions worldwide, the granites and volcanic rocks in southeast China show distinct characteristics of episodical occurrences, complex genetic types and formation processes, and close affinity with metallogeny.

华南花岗岩－火山岩具幕式多期次产出的特点，成因类型和形成过程错综复杂。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
