蚕庄金矿上庄矿区控矿构造特征及构造模拟

上庄矿区的主要控矿断裂具有多期活动的特点，主断裂、次级断裂及节理的多种组合方式控制了矿体的产出。运用断裂面波形模拟方法得出了控矿主断裂在成矿期的断裂面波形图，并以此对上庄矿区的深部矿体进行了预测。     

泌阳凹陷北部斜坡带构造特征及油气圈闭有效性

泌阳凹陷北部斜坡带断裂极为发育，主要发育NE向和NWW向两组正断层。NE向断层断距大，延伸距离远；NWW向断层断距相对较小，延伸较短。斜坡带由于构造破碎，断层发育，圈闭类型多为断块、断鼻及断层 岩性复合型圈闭。因此，对北部斜坡带断层的展布和交切规律的研究，是识别该区圈闭的关键。     

山东蒙阴县埠洼金矿与韧性剪切带的关系

埠洼金矿受NW向台上-盘东沟韧性剪切带的控制，矿体产于剪切带中南部的英云质超糜岩中，矿体呈右行侧列式分布，成矿体用与韧性剪切变形变质导致的动力分异作用密切相关，赋矿空间为韧-脆性剪切作用形成的扩容带，是在韧性剪切基础上形成的金矿床。

安徽铜陵地区蚀变流体填图方法的探讨

蚀变流体填图是一项区域流体地质调查研究工作 ,也是一项具有战略意义的、综合性的基础地质研究工作。区域大面积的流体填图工作的理论依据、思路方法、填图要素、技术要求和规范等还没有一套成熟的方法体系。在实施中国地质调查局和国土资源部科学技术司的“铜陵地区蚀变流体填图”项目中 ,探讨了流体填图的理论依据、思路方法、研究内容和填图要素 ,对填图单位制定了 3级填图单元等级体制 ,即流体系统流体子系统流体单元。在铜陵地区划分出 4个流体系统 ,7个流体子系统和 18个流体单元。     

~(40)Ar/~(39)Ar Dating of Deformation Events and Reconstruction of Exhumation of Ultrahigh-Pressure Metamorphic Rocks in Donghai, East China

Recent investigations reveal that the ultrahigh-pressure metamorphic (UHPM) rocks in the Donghai region of East China underwent ductile and transitional ductile-brittle structural events during their exhumation. The earlier ductile deformation took place under the condition of amphibolite facies and the later transitional ductile-brittle deformation under the condition of greenschist facies. The hanging walls moved southeastward during both of these two events. The 40Ar/39Ar dating of muscovites from muscovite-plagioclase schists in the Haizhou phosphorous mine, which are structurally overlain by UHPM rocks, yields a plateau age of 218.0±2.9 Ma and isochron age of 219.8Ma, indicating that the earlier event of the ampibolite-facies deformation probably took place about 220 Ma ago. The 40Ar/39Ar dating of oriented amphiboles parallel to the movement direction of the hanging wall on a decollement plane yields a plateau age of 213.1±0.3 Ma and isochron age of 213.4±4.1 Ma, probably representing the age o     

Cascaded Evolution of Mantle Plumes and Metallogenesis of Core- and Mantle-derived Elements

Mineral deposits are unevenly distributed in the Earth's crust, which is closely related to the formation and evolution of the Earth. In the early history of the Earth, controlled by the gravitational contraction and thermal expansion, lighter elements, such as radioactive, halogen-family, rare and rare earth elements and alkali metals, migrated upwards; whereas heavier elements, such as iron-family and platinum-family elements, base metals and noble metals, had a tendency of sinking to the Earth's core, so that the elements iron, nickel, gold and silver are mainly concentrated in the Earth's core. However, during the formation of the stratified structure of the Earth, the existence of temperature, pressure and viscosity differences inside and outside the Earth resulted in vertical material movement manifested mainly by cascaded evolution of mantle plumes in the Earth. The stratifications and vertical movement of the Earth were interdependent and constituted the motive force of the mantle-core movement.
