1燕山造山带后石湖山碱性环状杂岩体的成因与形成过程显示文摘后石湖山杂岩体是与垮塌破火山口有关的碱性环状杂岩体,主要由呈环形分布的碱性火山岩、环状岩墙(斑状石英正长岩)、嵌套的中心复式岩株(晶洞碱长花岗岩和斑状碱长花岗岩)和锥状岩席(石英正长斑岩和花岗斑岩)组成.LA-ICPMS锆石U-Pb年代学分析表明,斑状石英正长岩环状岩墙、石英正长斑岩和花岗斑岩锥状岩席的侵位年龄分别为119±3Ma、121±2Ma和121±2Ma.该环状杂岩体火山岩与侵入岩的形成年龄相近,体现了它作为火山-侵入杂岩体的特征.斑状石英正长岩富碱(Na2O+K2O=10.0%~10.5%),K2O含量较高(5.21%~5.42%),具正的Eu异常(Eu/Eu*=1.05~1.40).碱长花岗岩和斑岩均具有富碱、高FeOtot/MgO、Ga/Al、Zr、Nb和REE值(Eu除外),以及低Al2O3、CaO、MgO、Ba、Sr和Eu含量的特征,都属于A型花岗岩质岩石.其中斑岩为铝质A型花岗岩,具有高的初始岩浆温度(880~901℃).所有A型花岗质岩石均具有较富集的Nd同位素组成,εNd(t)值变化于-13.9~-12.2之间.斑状石英正长岩是下地壳中-基性麻粒岩和片麻岩部分熔融产生的熔体与幔源玄武质岩浆混合,后又发生单斜辉石分离结晶的产物;碱长花岗岩源于上地壳长英质岩石部分熔融产生的熔体与幔源玄武质岩浆混合,随后经历长石的分离结晶作用而成;斑岩是受幔源岩浆底侵加热的上地壳长英质岩石的部分熔融产生的熔体,并经历了长石的分离结晶作用而产生.该环状杂岩体的形成过程可以概括为:(1)火山爆炸性喷发形成大量的碱性火山熔岩和火山碎屑岩;(2)地下岩浆房空虚导致压力下降,其顶板围岩失稳而沿火山口周围近直立的环状断裂垮塌,形成塌陷的破火山口.与此同时,下覆岩浆房的岩浆被动挤入环状断裂而形成斑状石英正长岩环状岩墙;(3)浅部地壳的长英质岩浆房过压,促使其高温过碱质A型花岗质岩浆上升侵位形成了中心的斑状碱长花岗岩岩株,这些岩浆的上涌导致上覆围岩产生倾角中-陡的、内倾的锥状裂隙,为石英正长斑岩锥状岩席侵位提供了空间;(4)浅部岩浆房复活,高温过碱质A型花岗质岩浆再度上升侵位形成被嵌套的晶洞碱长花岗岩岩株.同样,这种岩浆的再度上侵导致上覆围岩产生了倾角较陡而内倾的锥状裂隙,为花岗斑岩锥状岩席提供了侵位空间.后石湖山碱性环状杂岩体的形成是华北东部早白垩世与克拉通破坏相关的伸展构造体制下的产物,这种构造体制可能与古太平洋板块的俯冲作用有关.文霞 马昌前 桑隆康 Roger Mason 佘振兵 熊富浩 2013地球科学(中国地质大学学报)2013,38,4:6
2Occurrence, thermal evolution and primary migration processes derived from studies of organic matter in the Lucaogou source rock at the southern margin of the Junggar Basin, NW China显示文摘The Lucaogou Formation carbonate-rich oil shale source rock is exposed at the southern margin of the Junggar Basin, Xinjiang, NW China. We have sampled it in detail and conducted microstructural, mineralogical and geochemical studies, including thin section petrography, UV fluorescence petrography, X-ray diffraction, vitrinite reflectance, bitumen reflectance, fluid inclusion analysis and Raman spectroscopy. Organic matter is disseminated through the carbonate-bearing siltstone source rocks and concentrated in numerous bedding parallel stylolites and in two sets of carbonate veins, one along bedding parallel fractures and the other cross-cutting stylolites and bedding. The research about maturity of organic matter finds vitrinite reflectance values increase from the dispersed kerogen (0.64%) to the stylolites (the one of oriented vitrinite is 0.72% and the one of migrated bitumen is 2.38%); Homogenization temperatures of fluid inclusions in veins containing hydrocarbon fluid inclusions show an increase from 178.5℃ in the bedding parallel veins to 222℃ in the cross-cutting veins, confirmed by Raman spectroscopy. These results support a model of progressive heating accompanied by fluid loss during later stages of thermal maturation of source rock and the onset of primary migration. Obviously, the occurrence of organic matter is the trace of hydrocarbon primary migration, and the bedding lamination surfaces and cross-cutting fissures are the principal pathways of hydrocarbon-bearing fluids migration. Bedding lamination surfaces evolved into stylolites along the earliest primary migration pathways, followed by bedding parallel and cross-cutting fissures.JIAO YangQuan WU LiQun HE MouChun ROGER Mason WANG MinFang XU ZhiCheng 2007Science China Earth Sciences2007,50,z2:4

4继承发扬优良传统 精心打造精品课程——中国地质大学“岩石学”课程发展历程显示文摘本文回顾了中国地质大学“岩石学”课程自著名的岩石学家、教育家池际尚院士开创至今的59年光辉历程,包括“岩石学”课程开创和奠基(1950~1966),“文化大革命”的破坏及其后的复苏(1966~1980)、“岩石学”课程全面发展(1981~1996)和面向21世纪“岩石学”课程的新变革、新发展(1997~)等四个阶段。重点叙述了第四阶段在全球化时代背景下,继续继承和发扬重教学、重实践、重改革的优良传统,进一步精心打造“岩石学”精品课程的变革和发展。桑隆康 马昌前 郑建平 肖龙 周汉文 朱云海 张宁 余淳梅 佘振兵 Roger Mason 2009中国地质教育2009,18,2:4
5用接触变质作用标志初步判别北京房山岩体的岩浆侵位机制显示文摘近同心状房山岩体接触变质晕中变斑晶-基质关系与变质作用P-T轨迹样式的结合可以区分岩浆底劈式侵位与气球膨胀式侵位机制.例如,该房山岩体南侧接触变质晕中的下马岭组泥质变质岩的变斑晶-基质关系显示强烈的面状压扁应变变形,其变质作用P-T轨迹具等压加热趋势,综合前人成果估算该岩体4个依次侵位的岩石单元的最终就位岩浆结晶深度彼此近于一致,倾向于认为该岩体的岩浆侵位机制为气球膨胀式.陈能松 陈冰寒 Roger Mason 杨婷婷 夏彬 刘嵘 王国庆 徐冉 2018地球科学2018,43,1:4
