Petrogenetic processes in the ultramafic, alkaline and carbonatitic magmatism in the Kola Alkaline Province: a review [PDF]
, 2005 Igneous rocks of the Devonian Kola Alkaline Carbonatite Province (KACP) in NW Russia and eastern Finland can be classified into four groups: (a) primitive mantle-derived silica-undersaturated silicate magmas; (b) evolved alkaline and nepheline syenites; (

Oikos, EarlyView.Biodiversity dynamics in heterogeneous landscapes is the result of a complex interplay between movement processes of organisms within and between habitat patches, and niche filtering processes due to spatially varying environmental conditions. Disentangling the relative influences of these different processes on community assembly and dynamics is a ...

Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina [PDF]
, 2017 The North Patagonian Massif is an Argentinean plateau that has an average height of 1200 m and stands from 500 to 700 m above the neighboring areas. During Paleogene, it suffered a sudden uplift of more than 1200 m without noticeable internal deformation;

People and Nature, EarlyView.Abstract Afromontane ecosystems, characterised by mosaics of fire‐adapted grassy ecosystems and fire‐sensitive forests, are biodiversity hotspots facing escalating pressures from non‐native species, climate and land‐use change. Madagascar's Central Highlands is one such hotspot, hosting woodlands dominated by endemic Uapaca bojeri (tapia) which are ...

Development of natural underground ore mining technologies in energy distributed massifs [PDF]
, 2019 The object of research is the technology and facilities for underground mining of ores in the disrupted massifs. One of the most problematic places is the formation of man-made voids; which influence the occurrence and redistribution of stress-strain ...

The Age and Origin of Block Deposits in the Victorian Alps, Australia
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in
