		mineralogical studies on a new meteorite, which was found in 
		August 2012 near the village of Csátalja, Hungary (46°0'21-N; 
		18°59'27'E). The Csátalja meteorite is classified as a H4-5 
		ordinary chondrite with shock stage S2 and a degree of 
		weathering W1 and the total mass is 15 kg. The Csátalja 
		meteorite is characterized by well-defined chondrules composed 
		either of olivine or pyroxene. X-ray diffractogram shows the 
		primary phases olivine, pyroxene, kamacite, and albite. Metal 
		particles were extracted from the bulk powdered samples exhibit 
		only kamacite and small amounts of the intergrowth 
		taenite/kamacite. Raman spectra of forsterite indicate that 
		Csátalja meteorite suffered from relatively low shock pressure 
		regime. The texture of chondrules varies from nonporphyritic 
		(e.g., barred olivine, radial pyroxene) to porphyritic ones 
		(e.g., granular olivine as well as olivine pyroxene). The 
		meteorite name has not yet approved by the Nomenclature 
		Committee of the Meteoritical Society.},

	abstract = {This study demonstrates that the unpolarized attenuated total reflectance Fourier transform infrared spectroscopy (ATR FTIR) is a practical and quick tool to distinguish different types of sediments in landslide-affected areas, and potentially other types of physical environments too. Identification and quantification of minerals by ATR FTIR is implemented on a set of powdered natural sediments from a loess landslide (Kulcs, Hungary). A protocol including sample preparation, analytical conditions and evaluation of sediment ATR spectra is outlined in order to identify and estimate major minerals in sediments. The comparison of the defined FTIR parameters against qualitative and quantitative results of X-ray diffraction and thermal analysis was used to validate the use of ATR FTIR spectroscopy for the considered sediments. The infrared band areas and their ratios (water/carbonates; silicates/carbonates; kaolinite) appear to be the most sensitive parameters to identify strongly weathered sediments such as paleosols and red clays which most likely facilitate sliding and could form sliding zones. The effect of grain size and orientation of anisotropic minerals on the wave number and intensity of some major absorption bands is also discussed.},
