“…The Mo ¨ssbauer spectra of moon-white Ru porcelain glaze of the Yuan dynasty were also reported. 303,304 They showed the existence of three iron components, Fe 2z , Fe 3z , and a magnetically split component of Fe 3 O 4 with a total of 60% of Fe 2z 303,304 When the glaze is fired in a reducing atmosphere, it undergoes nitrification at about 950uC and recrystallisation above 1000uC. Based on the value of the quadrupole splitting and the intensity of the Fe 2z component, the original firing conditions were deduced to be 1150¡50uC in a reducing atmosphere.…”

A comprehensive review is presented of the recent contributions Mo ¨ssbauer spectroscopy has made in materials science and engineering. After a brief introduction to the basic methodology, examples of the application of 57 Fe and 119 Sn Mo ¨ssbauer spectroscopy in both transmission and back-scattering mode are presented and discussed. Recent technological and software developments of this technique are also included. Coverage is further extended to recent, pertinent developments in space research and also in biological science and technology where Mo ¨ssbauer techniques are very widely used. Efforts have also been made to cover applications to archaeological samples where Mo ¨ssbauer spectroscopy is an important analytical tool.

“…Marine, volcanic-rich sediments are composed of chemically weathered clay minerals and physically weathered finegrained rock-forming minerals (Chen et al 1994). The mineralogical and geochemical signatures of these sedimentary successions have been successfully used to infer constraints on the paleoenvironmental evaluation of some sedimentary basins (Bhatia & Crook 1986).…”

Abstract:The Hazar-Maden Basin sediments were deposited along the southern branch of the Neotethys Ocean margin during Late Maastrichtian-Middle Eocene times. X-ray powder diffraction (XRD), ICP-AES, ICP-MS and scanning electron microscopy (SEM) were performed on samples of the Upper Maastrichtian-Middle Eocene Hazar Group and the Middle Eocene Maden Complex from the Hazar-Maden Basin to investigate the main effects of depositional environmental parameters in three sections belonging to deeper marine (slope), proximal arc volcanic (Mastarhill and Yukar1bag sections) and shallow platform marine (Sebken section) settings. Marine sediments contain clay minerals (smectite, smectite/chlorite, chlorite, illite, interstratified illite/smectite, illite/chlorite, palygorskite), clinoptilolite, quartz, feldspar, calcite, dolomite, opal-CT and hematite. The clays are dominated by iron-rich smectites. La, Zr and Th concentrations are high in the shallow marginal Sebken section where the terrestrial detrital contribution is significant, while Sc and Co are more dominant in the deeper marine (slope) Yukar1bag section, which is represented by basic-type volcanism and a higher contribution of hydrothermal phases. In a chondrite-normalized REE diagram, the negative Eu anomaly in samples from Sebken, the section which was deposited in a shallow marine environment, is less significant than that of the other two sections indicating the presence of a high terrestrial contribution in that part of the basin. A decrease in LREE N /HREE N and La N /Yb N , La N /Sm N ratios from Sebken to Mastarhill and the Yukar1bag sections indicates deepening of the basin and an increasing contribution of volcanism in that direction.
