Taihangshan orogen, called as tectonomagmatic belt, is thought to be a part of Mesozoic circum Pacific magmatic arc. On the basis of the studying of intrusive rocks of Taihang Mountains in Yanshanian, we compare the petrochemical and geochemical characteristics and their generation information from intrusives of different periods and regions in details. We suggest the idea of “Taihangshan style orogen” and its generation model. It is suggested that Taihangshan orogen is a new orogenic type, which is controlled by the long distance effect of the subduction between the plate boundaries of Europe Asian and Pacific Ocean, marked by extensive magmatic activity, and characterized by the two way thickening of the crust along the depth dimension.

黑龙江省黑河地区广泛发育侏罗—白垩纪火山岩,但是该火山岩的岩石组合、成因和所表征的大地构造环境目前有很大的争议。本文对该套火山岩开展详细的岩石学、岩石地球化学等研究。该火山岩形成于早白垩世,主要以安山岩-英安岩-流纹岩为主,包含英安岩、安山岩、粗面岩、流纹岩、安粗岩、玄武安山岩、粗面英安岩、钾玄岩、歪长粗安岩,因此属于弧火山岩的组合。该区火山岩主要为亚碱性系列,岩石Na_2O/K_2O比值一般>1.2。A/CNK在1附近,为准铝质-过铝质岩石。SiO_2-TFeO/MgO图上既有钙碱性系列(包括低铁钙碱性系列),又有拉斑系列。SiO_2-K_2O图上主要为中钾钙碱-高钾钙碱系列。SiO_2-(Na_2O+K_2O-CaO)图上主要为钙碱系列、碱钙系列和碱性系列,在SiO_2-MgO图中主要落入实验玄武岩的局部熔融范围和镁安山岩系列范围。痕量元素蛛网图显示富集大离子亲石元素,K、La、Zr、Hf、Tb、Tm为峰,亏损Nb、Ta、Ti、Y、Yb等高场强元素。稀土元素球粒陨石标准化配分模式为缓右倾型的模式,轻稀土相对富集,重稀土内部分馏不明显,具有微弱负Eu异常。大部分岩石具有高Sr低Y的特征,其中一些岩石具有adakite岩的特征。上述特征均指示弧火山岩的特征。结合构造环境判别认为该火山岩形成于与洋俯冲有关的环境,推测岩浆可能的源区为俯冲的洋壳、上覆的地幔楔、兴安弧的下地壳。

大型超大型金属矿床形成的深部物质组成和壳幔结构一直是地学研究中被关注的焦点和难点问题。胶东地区发育很多(燕山期)的大型超大型的金矿,是我国著名的金矿集区。本文基于板块构造理论,通过揭示区域火成岩、致矿火成岩组合及其特征,探讨金矿发育时的深部物质组成和壳幔结构。区域上成矿前的侵入岩组合为含少量英云闪长岩+奥长花岗岩(TT)的花岗闪长岩+花岗岩(G1G2)组合;区域上发育的青山群为含有高镁安山岩(HMA)和镁安山岩(MA)的玄武安山岩安山岩英安岩流纹岩以及粗安岩玄粗岩粗面岩组合;矿集区的致矿火成岩组合为含有高Mg闪长岩类(HMgδ)+Mg闪长岩类(Mgδ)的宽谱系岩墙群(WSDS),岩性从基性到酸性均有。上述火成岩组合,以及TTG1、HMA与MA系列火山岩、HMgδ和Mgδ的存在,指示弧火成岩的组合,其各种岩石地球化学特征亦具有弧的特征,因此,上述火成岩及金矿形成于洋俯冲环境,具有俯冲带的壳幔结构和物质组成。各种不同的火成岩指示其可能分别来源于俯冲带不同部位的局部熔融,指示洋壳、上覆地幔楔以及上覆陆壳具有异常热的壳幔结构,即热的洋壳、热的上覆地幔(软流圈)、热的陆壳。致矿火成岩事件、成矿事件均在大规模的壳源(或壳幔)侵入岩浆活动之后。

To the Editor:Patients with severe persistent asthma experience greater morbidity with more impairment in quality of life despite higher use of health care resources and being treated with existing asthma treatments such as inhaled corticosteroids and b-agonists,and sometimes oral corticosteroid(OCS)***-2(T2)high asthma has been identified as a phenotype that responds to targeted T2 biologic therapies such as anti-IgE,anti-interleukin(IL)5,or anti-IL5Ra and anti-IL4Ra monoclonal antibodies,which are currently available in Europe and North America,and are currently introduced in the rest of the world.[1]
