AbstractMinerals are the building blocks of clastic sediments and play an important role with respect to the physico-chemical properties of the sediment and the lithostratigraphy of sediments. This paper aims to provide an overview of the mineralogy (including solid organic matter) of sediments as well as suspended matter as found in the Netherlands (and some parts of Belgium). The work is based on a review of the scientific literature published over more than 100 years. Cenozoic sediments are addressed together with suspended matter and recent sediments of the surface water systems because they form a geoscientific continuum from material subject to transport via recently settled to aged material. Most attention is paid to heavy minerals, clay minerals, feldspars, Ca carbonates, reactive Fe minerals (oxides, siderite, sulphides, glauconite) and solid organic matter because they represent the dominant minerals and their properties form a main issue in subsurface and water management. When possible and relevant, the amounts, provenance, relationship with grain size distribution, early diagenesis and palaeohydrological evolution are described. Tables with statistical data about the mineral contents and isotopic composition of carbonates and organic matter are presented as overviews. The review on the mineralogy of Dutch fluvial and marine environments is more extensive than that for the other sedimentary environments because the first two have been studied much more intensively than the others and they also form the larger part of the Dutch deposits. The focus is on the natural background mineralogy of Dutch sediments, but this is hard for recent sediments, largely because the massive hydraulic infrastructure present in the Netherlands has probably also affected the mineralogy and geochemistry of sediments deposited in recent centuries. Many findings are summarised, several of which lead to more general insights for the Dutch situation. Ca carbonates in sediments often have several provenances and thus must be considered as mixtures. Dolomite is commonly present in addition to calcite. The importance of biotite as weatherable mica is unclear. Weathering of heavy minerals plays some role but it is unclear in which way it affects the heavy mineral associations. Clays are usually dominated by illite, smectite and their interstratified variant, while kaolinite is usually below 20% and chlorite below 5%. Vermiculite is a minor constituent in fluvial clays and its illitisation presumably happens during early diagenesis in the marine environment. Opaque Fe hydroxides can be present in addition to Fe oxyhydroxide coatings and both will play a role in redox chemistry as reactive Fe minerals. Feldspars in marine sediments must be present but they have not been properly studied. The genesis of rattle stones and carbonate concretions has not been completely elucidated. The fraction of terrigeneous organic matter in estuarine and coastal marine sediments is substantial. The available data and information are spread irregularly over the country and the reviewed information discussed in this paper is derived from relatively small-scale studies dealing with a limited amount of analysed samples. Much information is available from the Scheldt estuaries in the southwestern part of the Netherlands partly due to the severe contamination of the Western Scheldt in recent decades.

Two localities (Al-Marij and Laik) were selected to investigate the type of Quartz Grains from crustal material formed by evaporation of waters discharged by springs in Hit area, western Iraq, Previous studies on the crustal material (1,2) showed that the water discharged by these springs are associated with Abu-Jir fault system which run parallel to the Euphrates river,Factor analyses of the crustal and soil materials (50 samples analysed for 16 variables)(2) showed five factors; the first factor includes SiO2, Al2O3 and TiO2 with positive factor loading, and CaO, L.O.I. with negative loading and hence lead to the conclusion that the distribution of these variables is a reflection of transported clay material.This study concentrates on the use of SEM to investigate the contribution of Quartz grains found in the crustal material on two selected sites.

New Religion

This article examines the emergence of Zoroastrianism in the Kurdistan Region of Iraq since 2015 as a new religion inspired by Kurdish nationalism, feminism, ecologism and humanism. The author argues that the emergence of Zoroastrianism at this particular time is due to a combination of the rise of the Islamic State in Iraq and the Levant in 2014, legislative change and the importance some Kurdish nationalists historically attached to Zoroastrianism as the suggested original religion of the Kurds. The article outlines the historical context of Zoroastrianism in Kurdistan, and then explores the origins, beliefs and organisational structure of Kurdish Zoroastrianism. Also discussed are the legislative changes enabling the rise of the movement since 2015. This study draws on interviews with Kurdish Zoroastrian leaders as well as with representatives from the World Zoroastrian Organization, the Kurdistan Regional Government’s Ministry of Endowments and Religious Affairs and the Alliance of Iraqi Minorities.ABSTRACT IN KURMANJIJi nû ve pêxistina agir: Baweriya Zerduştî li Kurdistana IraqêEv gotar, li ser peydabûna Zerduştiyê li Herêma Kurdistanê ya Iraqê hûr dibe, ku ji 2015an vir ve wek dînekî nû yê ji netewegeriya kurd, femînîzm, ekolojîzm û humanîzmê îlham wergirtî tê dîtin. Nivîskar îddia dike ku peydabûna Zerduştiyê ya bi taybetî wê demê ji ber hejmareke sedeman e: di 2014an de peydabûn û xurtbûna Dewleta Îslamî li Iraqê û Levantê, guherîna qanûnî û girîngiya nêrîna hin netewegerên kurd ku ji aliyê dîrokî Zerduştiyê wek dînê resen ê kurdan dibînin. Gotar, çarçoveya dîrokî ya Zerduştiyê li Kurdistanê bi kurtî rave dike û paşê li kok, bawerî û avahiya rêxistinî ya Zerduştiya kurdî dikole. Ji hêleke din, nîqaş dike ku guherînên hiqûqî ji 2015an vir ve rê li ber xurtbûna tevgerê vekiriye.
