Rietveld方法的R.A.Young程序的改进及其在矿物学中的应用

Ｒｉｅｔｅｖｌｄ方法是采用粉末衍射进行晶体结构修正及解析的一种方法。Ｒｉｅｔｖｅｌｄ方法的代表软件是Ｒ．Ａ．Ｙｏｕｎｇ程序。该程序给用户使用的主要困难是由于其输入控制文件（ＩＣＦ），是一个严格格式化的文本文件，其次是在运行时受到常规内存的限制。本文介绍了用ＭｉｃｒｏｓｏｆｔＣ７．０及ＭｉｃｒｏｓｏｆｔＳＤＫ３．１对Ｒ．Ａ．Ｙｏｕｎｇ程序的改进，（１）用对话框输入各种控制参数，形成初始化文件（ＩＮＩ），然后再将其转换为输入控制文件（ＩＣＦ）；（２）用Ｗｉｎｄｏｗｓ多文档界面（ＭＤＩ）实现图形显示，编辑和存储；（３）设计一软件接口，使在Ｗｉｎｄｏｗｓ下启动Ｒ．Ａ．Ｙｏｕｎｇ计算程序；（４）用ＦＯＲＴＲＡＮＰｏｗｅｒＳｔａｔｉｏｎ编译器对Ｒ．Ａ．Ｙｏｕｎｇ程序源代码进行重新编译，使其不受常规内存限制。用改进后的Ｒ．Ａ．Ｙｏｕｎｇ程序，对绿辉石的结构进行了修正

Définition d'une limite multicritère ; stratigraphie du passage Campanien–Maastrichtien du site géologique de Tercis (Landes,SW France)Definition of a multi-criteria boundary; stratigraphy of the Campanian–Maastrichtian interval of the geological site at Tercis (Landes,SW France)

Lithostratigraphy, physicochemical stratigraphy, biostratigraphy, and geochronology of the 77–70 Ma old series bracketing the Campanian–Maastrichtian boundary have been investigated by 70 experts. For the first time, direct relationships between macro- and microfossils have been established, as well as direct and indirect relationships between chemo-physical and biostratigraphical tools. A combination of criteria for selecting the boundary level, duration estimates, uncertainties on durations and on the location of biohorizons have been considered; new chronostratigraphic units are proposed. The geological site at Tercis is accepted by the Commission on Stratigraphy as the international reference for the stratigraphy of the studied interval. To cite this article: G.S. Odin, C. R.

Quaternary stresses revealed by calcite twinning inversion: insights from observations in the Savonnières underground quarry (eastern France)

Calcite samples were extracted both from the rock matrix and the superficial coating of a karstified fault plane of an underground quarry, located in the eastern border of the Paris basin. The karstification is dated as Quaternary. Analysis of mechanical calcite twinning reveals that only the calcite matrix has also undergone a compression trending WNW that can be attributed to the Mio-Pliocene alpine collision. Both coating and matrix have undergone a strike-slip regime with σ₁ roughly trending north–south, that could correspond to the regional present-day state of stress, a strike-slip compression rather trending NNW, modified by local phenomena.
