Average physical structure of cratonic lithosphere, from thermodynamic inversion of global surface-wave data [0.03%]
基于全球表面波数据的克拉通地幔热结构统计平均模型研究

Seismic and mantle-xenolith data both show that cratons have the thickest, coldest lithosphere of the Earth's tectonic environments. Yet, the quantitative depth distributions of temperature, seismic velocity and mass density (herein referre...
New geochemical and Sr-Nd-Hf isotopic constraints on the genesis of kimberlites and ultramafic lamprophyres from the Adelaide Fold Belt and Gawler Craton, South Australia [0.03%]
南澳大利亚阿德莱德褶皱带和盖勒尔克拉通金伯利岩和超镁铁质闪长岩的地球化学及Sr-Nd-Hf同位素制约因素

Hayden Dalton et al.
This study investigates the geochemical and isotopic characteristics of Jurassic kimberlites and ultramafic lamprophyres (UMLs) from four clusters within the Adelaide Fold Belt (AFB) and two within the Gawler Craton in South Australia. Petr...
Are the [6]-coordinated sites in tourmaline in certain cases partially vacant? [0.03%]
Tourmaline的[6]配位站点在某些情况下部分空置吗？
Andreas Ertl
Andreas Ertl
Tourmaline has two different [6]-coordinated sites, the Y site and the Z site. Vacancies were reported from both sites. Based on high-quality chemical and single-crystal structural data it usually needs increasing proportions of short-range...

"Multi-method-approach" has now been for many years the buzzword in marble provenance analysis. Nevertheless a true combination of the results of different analytical methods is rarely applied in the sense of the combined simultaneous use o...
The parisite-(Ce) enigma: challenges in the identification of fluorcarbonate minerals [0.03%]
含氟碳盐矿物巴黎石-(Ce)鉴定之谜

The sustained transportation of particles in a suspension commonly results in particle attrition leading to grain size reduction and shape modification. Particle attrition is a well-studied phenomenon that has mainly focussed on sediments p...
Structural investigations of the two polymorphs of synthetic Fe-cordierite and Raman spectroscopy of hexagonal Fe-cordierite [0.03%]
合成Fe-硅线石两种多晶型体的结构研究及六方Fe-硅线石的拉曼光谱研究
Udo Haefeker,Reinhard Kaindl,Peter Tropper et al.
Udo Haefeker et al.
The crystal structures of synthetic hexagonal and orthorhombic Fe-cordierite polymorphs with the space groups P6/mcc and Cccm were refined from single-crystal X-ray diffraction data to R1, hex = 3.14 % and R1, ortho = 4.48 %. The substituti...

Christoph Lenz et al.
In this paper, possibilities and limits of the application of REE3+ luminescence (especially the Nd3+4F3/2 → 4I9/2 emission) as structural probe are evaluated. Important factors controlling the Nd3+ luminescence signal are discussed, inclu...
Cu- and Mn-bearing tourmalines from Brazil and Mozambique: crystal structures, chemistry and correlations [0.03%]
含铜和锰的碧玺晶体结构、化学及关联性：来自巴西和莫桑比克的例子
Andreas Ertl,Gerald Giester,Ulrich Schüssler et al.
Andreas Ertl et al.
Cu- and Mn-bearing tourmalines from Brazil and Mozambique were characterised chemically (EMPA and LA-ICP-MS) and by X-ray single-crystal structure refinement. All these samples are rich in Al, Li and F (fluor-elbaite) and contain significan...
Magma hybridization in the Western Tatra Mts. granitoid intrusion (S-Poland, Western Carpathians) [0.03%]

In the Variscan Western Tatra granites hybridization phenomena such as mixing and mingling can be observed at the contact of mafic precursors of dioritic composition and more felsic granitic host rocks. The textural evidence of hybridizatio...
