Diogo Rosa's research while affiliated with Geological Survey of Denmark and Greenland and other places

... In Europe, the Geological Survey Organisations (GSOs) contribute by compiling, gathering and storing the most up to date information, as well as long-term data series, on raw materials at national and regional levels. Supported by the EC, the GSOs have joined forces to compile, harmonize and share data on raw materials occurrences and mines, as well as updating the European Minerals Yearbook with data on production, trade, resources and reserves Jørgensen et al. 2022). The outcomes are illustrated as interactive maps at the European Geological Data Infrastructure (EGDI). ...

... The Rinkian belt is located north of the Nagssugtoqidian orogen in West Greenland and is exposed across 5° of latitude between Disko Bugt and Melville Bugt (Fig. 1A) (Grocott and Pulvertaft, 1990). It has a basement of Archean orthogneiss, with volumetrically minor amphibolite and paragneiss, overlain by late Neoarchean metasedimentary rocks of the Qeqertarssuaq Formation and Paleoproterozoic metasedimentary and metavolcanic rocks of the Karrat Group and the Anap nunȃ Group (Escher and Burri, 1967;Escher and Pulvertaft, 1976;Pulvertaft, 1967, 1987;Garde and Steenfeldt, 1999;Watt, 2019;Thrane, 2021;Guarnieri and Baker, 2022;Guarnieri et al., 2022aGuarnieri et al., , 2022bGuarnieri et al., , 2022c. The belt is divided into a north Rinkian fold-thrust belt (FTB) and a south Rinkian FTB by a large hypersthene granite-the Prøven Igneous Complex (PIC) (Fig. 1A) (Grocott and Pulvertaft, 1990;Thrane et al., 2005). ...

... Supracrustal rocks in central West Greenland belong to the Karrat Group that initiated after c. 2000 Ma in an intra-cratonic rift basin with basal quartzites overlaying Archean gneiss of the Rae Craton (Guarnieri et al. 2022a;Guarnieri et al. in press). The rift basin evolved to a back-arc basin with associated sub-alkalline volcanism (Guarnieri et al. 2022b), concomitant with the emplacement of arc-related granitoids of the Prøven Igneous Complex between 1900 and 1850 Ma) (Thrane et al. 2005;Guarnieri et al. 2022c;Kokfelt et al. 2023). The arc-continent collision initiates the east-ward structuring of the Rinkian Orogen as back-arc fold and thrust system antithetic to northeastward oceanic subduction. ...

... These datasets have significant potential for the mining industry as they allow for the integrated representation, analysis, and interpretation of geometric and spectral features. As recently shown in several studies, the hypercloud approach can effectively support exploration and mining activities (e.g., Booysen et al., 2022;Guarnieri et al., 2022;Kirsch et al., 2018;Lorenz et al., 2018;Murphy et al., 2015;Thiele et al., 2021). ...

... Although there are several (ongoing) attempts to promote benchmarking and open science in the remote sensing field by developing exhaustive lists of available datasets [1,2], evaluation servers (e.g., DASE 1 ), cloud services (e.g., Amazon Web Services 2 , Microsoft's Planetary Computer 3 , Radiant Earth's MLHub 4 ), and benchmark datasets (e.g., [3,4,5,6]), novel applications within the fields of geomorphology, and geology remain sparse and unclear. Also, generally applicable reference data in remote sensing and geosciences for evaluating machine learning approaches are still not available in sufficient quantity and quality [7,8]. ...

... Despite the importance of oxidized brines in the genesis of sedimenthosted deposits, reviews of the secular distribution of sediment-hosted Zn systems by Leach et al. (2010) and Rosa et al. (2023) revealed only a few deposits which are regarded to have formed within the 2.45-1.85 Ga range in Earth history; the period during which the atmosphere and shallow oceans evolved from anoxic to mildly oxygenated conditions (GOE, Holland, 2006). ...

... Modern high-tech production and science-intensive technologies are largely based on the use of rare metals generally recognized as critical minerals [1][2][3][4][5][6]. Progress in the modern global economy is impossible without critical metals. ...

... Blue pentagons show outcropping mineral occurrences in dolomitic marbles and yellow pentagons correspond to surface projection of subsurface orebodies of the Black Angel deposit (including its satellite Nunngarut orebodies). Location of Fig. 9 is also shown (Rosa et al. 2018). The Rinkian Orogen is related to subduction and calc-alkaline magmatism between 1900 and 1850 Ma (Guarnieri et al. 2022c). ...

... Note that the term "SEDEX" is only used in this report for citations to historical publications, the CD term is the preferred term for clastic-dominated (CD) Zn-Pb deposits as per the usage described in Leach et al. 2010. Other workers classify the Black Angel deposit as an epigenetic Mississippi Valley-type (MVT) deposit (Carmichael 1988;Kolb et al. 2016;Rosa et al. 2017;Partin et al. 2021). Horn et al. (2019) disputed a MVT and SEDEX classification and favored a metamorphic Kipushi-style model. ...
