The paper studies accessory Cr-spinels from deep drill holes crossing the Nude-Poaz massif, which is a part of Monchegorsk mafic-ultramafic layered complex (2.5 Ga, Kola Peninsula, Russia). occur as two morphological types that differ in their chemical composition, i.e., first type are more aluminous, while second ferruginous and titaniferous. massif characterized by Fe-Ti trend known for intru...

Abstract Drilling related to development of the platinum-group element deposit J-M Reef Stillwater Complex returned samples a rare chromitite seam between anorthosite and norite in discordant anorthositic body. Plagioclase core An concentrations are marginally higher modestly reversely zoned on side (average Ancore = 83·8; average – Anrim –1·1) as compared with 82·5; +1·0). The anorthosites als...

Monchegorsk is an intrusion complex of basic and ultrabasic rocks the Paleoproterozoic age. This formed during active magmatic mobility that took place in NE Scandinavia 2.5 Ga years ago. These were subject intensive exploration exploitation at beginning 20th century, latter carrying on through to 21st century. contributed creation some different forms post-industrail mining infrastructure area...

BACKGROUND AND OBJECTIVES: This study aims down to evaluate the ability of chloride magnesium- aluminium- layered double hydroxides (4:1) for nitrate adsorption from the soil solution in successive cropping periods. METHODS: The study was conductedunder long-term cropping periods, including first crop): bell pepper; second crop: mentheae; third crop: cher...
