The mining/quarrying industry is a sector of industry where the role of LCA has been poorly investigated. Given the unique features of mining LCAs, a common methodology was implemented within the Sustainable Aggregates Resource Management (SARMa) Project (www.sarmaproject.eu) in order to boost adoption of LCA in the aggregate industry in South Eastern Europe. A key issue is the integration of three inter-dependent life cycles: Project, Asset and Product. The proposed methodology emphasises the importance of resource efficiency and recycling in the context of a Sustainable Supply Mix of aggregates for the construction industry.

Two basic views of terra rossa formation were distinguished, related to either a residual or detrital origin. More recently it has been suggested that it could derive from isovolumetric reaction between the parent carbonate rock and airborne material. The results have shown that only cutters can collect enough insoluble residue to become detectable after a period of existence within a steady lowering surface, must be either mixtures of diverse origins, or possibly completely allogenic.

Stable isotopes of carbon were used to trace organic and inorganic carbon cycles and biogeochemical processes, especially methanogenesis within different geologic substrates of the Pliocene lignite-bearing Velenje Basin in northern Slovenia. Lithotypes of lignite, coalbed gases, calcified woods (xylites), carbonate-rich sediments, and groundwaters were investigated. Carbon isotope (δ13C) values of the different lignite lithotypes ranged from −28.1 to −23.‰, with the variability likely a function of the original isotopic heterogeneity of the source plant materials and subsequent biogeochemical processes (i.e. gelification, fusinitization, mineralization of organic matter) during the early stage of biomass accumulation and diagenesis.

In this article authors presented results of joint cooperation between Geological survey of Slovenia and University of Pretoria, Republic of South Africa. In this research we tried to identify different sources of atmospheric dust on the highly industrialised area of Witbank by using indirect measurement method – street dust analysis. We measured world-record high content of selected metals. Three dominant influential factors were determined. Coal mining and connected electrical power production influence to the distribution of Al, Sr and Li. Traffic emits Cu, Pb, Sb and Sn, and metal smelting Fe, Co, Mn and V. According to spatial distribution we determined the range of dominant point-emitters (smelter) which are approximated to 20 km.

Contemporaneous alkali basaltic volcanism and fluvial sedimentation resulted in the formation of various mixed lithofacies that served in reconstruction of evolutionary history of the Grad Volcanic Field, from the initial maar to the late-stage tuff-ring.
