The l:200,000-scale map of the near-surface mineral resources of the Federal Republic of Germany

For those who deal with aspects of regional planning that are affected by the extraction of near-surface mineral resources, a simple map that shows the distribution of these resources accompanied by explanatory notes is essential; a preliminary 1:1 million-scale map was published in 1982. The Geological Surveys of the Federal States of Germany, in conjunction with the Federal Institute for Geosciences and Natural Resources, are compiling a series of maps that will cover the country at a scale of 1:200,000. When completed by the end of the next decade, this set of maps will consist of 57 sheets, each of which will be accompanied by explanatory notes. By the end of 1995, 17 sheets had been published BGR reports on the status of a Federal mineral-resource mapping program.     

南极长城站地区粘土矿物的空间分布规律与成因探讨

对南极长城站地区粘土矿物的空间分布与某些元素的地球化学行为之间的相关关系给予了较为详细的研究，并从地球化学方面探讨了粘土矿物的成因。研究表明，Ｃａ和Ｍｇ元素是高岭石生成的主要控制因子，高岭石的空间分布是两者共同作用的结果。Ｓｉ、Ｃａ、Ｍｇ和Ｆｅ元素的地球化学行为与蒙脱石在空间上的含量变化有明显的相关关系。Ｓｉ元素对蒙脱石的生成起到了较大的作用。     

黄土高原黄土、红色粘土与古湖盆沉积物关系

本文通过磁性地层学、古生物地层学、沉积学的对比研究，讨论了中国黄土高原地区黄土，红色粘土与该区重要古湖盆之一，古三门湖堆积物之间关系，并分析气候环境对它们的影响。主要结论如下：１）红色粘土与上覆黄土可以是连续沉积，并呈相渐变关系。２）中国黄土与三门组记录了布容正极性带与松山负极性带。Ｂ／Ｍ界限位于Ｌ８，Ｊ亚带位于标志层Ｌ９与Ｌ１５之间，大约Ｓ１０－Ｓ１３之间，Ｏ亚带位于Ｓ２２－Ｓ３３，或三门组之中。Ｍ／Ｇａ界限对应于黄土与红土界限。并基本对应于三门组与游河组界限。３）红色粘土（三趾马红粘土）并非仅仅是中新世保德期沉积物。它包括上新统与中新统，上新世静乐组记录了高斯正极性带，吉尔伯特负极性带，中新世蓝田组记录了Ｅｐｏｃｈ５。４）古三门湖堆积包括早更新世早期三门组（１．２０—２．５０Ｍａ，松山负极性带），上新世晚期游河组（２．５０—３．５０Ｍａ，高斯正极性带），更早期的三门湖沉积未出露。三门组与午域黄土为同期异相沉积，记录了松山负极性带，游河组则与该区上部红色粘土（静乐组上段）为同期异相沉积，记录了高斯正极性带

不透明矿物所含单个低盐度流体包裹体液相组分SAM/AES实验研究:Ⅰ.原理与方法

针对与矿石矿物共存透明脉石矿物所含流体包裹体并不完全代表成矿流体，红外显微技术及EPMA、SEM等常规表面分析手段无法满足不透明矿石矿物所含单个低盐度流体包裹体研究的实际困难，本文首次成功地应用具同步扫描成象功能、电子束斑空间分辨率较高、信噪比较好的PHI595SAM／AES这一当代高灵敏表面分析技术，按单矿物分选→二次去离子水反复超声清洗→外真空热爆→在金属铟片上压制成样的实验流程对新疆阿尔泰多拉纳萨依金矿床含金黄铁矿所含单个低盐度流体包裹体的液相组成进行了静态定点分析，实验取得了满意结果。

Magmatic arc metamorphism: petrology and temperature history of metabasic rocks in the Coastal Cordillera of northern Chile

We investigated the metamorphic cooling history of underplated magmatic rocks at midcrustal depth. Granulites and amphibolites occur within the Jurassic magmatic belt of the Coast Range south of Antofagasta in northern Chile between 23°25' and 24°20' S. The protoliths of the metamorphic rocks are basic intrusions of Early Mesozoic age. They are part of the magmatically formed crust, and the essentially dry magmas were emplaced in an extensional regime. The granulites (clinopyroxene–orthopyroxene–plagioclase) show all stages of fabric development from magmatic to granoblastic fabrics. Pyroxene compositions were reset at temperatures around 800°  C independent of the stage of textural equilibration. The granulites were partially amphibolitized at upper amphibolite facies temperatures of 600–700°  C. Following cooling, a possible reheating to greenschist facies temperatures around 500°  C is indicated by prograde zoning in magnetite–ilmenite pairs. Mineral assemblages are not suitable for barometry, but a conservative estimation of the garnet-in reaction at given whole-rock compositions suggests maximum pressures in the granulite facies of around 5 kbar, and similar pressures are indicated by phengite barometry for the greenschist facies. The P–T  path of granulite–amphibolite metamorphism is one of slow cooling from magmatic temperatures with heterogeneous deformation. The thinning of the pre-Andean (Precambrian–Triassic) crust was apparently compensated by the magmatic underplating and this special tectonomagmatic setting caused the prolonged residence of the accreted rocks at midcrustal levels.
