Catodoluminescència del pigment de dins d'un tub d'una bombeta de baix consum degut al xoc amb electrons accelerats. Cal remarcar que quan funciona una bombeta de baix consum el fòsfor emet llum per fluorescència, degut a la radiació UV emesa pel mercuri de dins del tub i no per catodoluminescència.https://infominer.minercat.com/wp-content/uploads/2019/09/fig6.jpgFig6Figura 6.

El xoc dels electrons accelerats des del càtode cap a l'ànode (la moneda, al centre de la imatge) amb les parets del tub produeix una llum verdosa. Els electrons que han passat a través del forat de la moneda xoquen amb la mostra i li provoquen la luminescència taronja.https://infominer.minercat.com/wp-content/uploads/2019/09/fig-3-1.jpgFig 3 (1)Figura 3.

El pleocroisme dèbil de la clinoclasa és una propietat interessant  que permet diferenciar aquest arsenat de coure de color blau d'altres minerals similars. L'índex de refracció en les tres direccions del cristall és força diferent (va de 1,73 a 1,91) i això fa que quan gira la platina, a més del pleocroisme, es pugui observar un canvi molt accentuat en el relleu (a la dreta el relleu del cristall és molt més accentuat que a l'esquerra)https://infominer.minercat.com/wp-content/uploads/2018/11/fig-9-composicio-jarosita.jpgFig 9. composicio jarositaFigura 9.

Espectre Raman de la crosta blava al voltant dels forats del coure de la canalització. Clarament es tracta d'un sulfat hidratat i l'espectre coincideix molt bé amb el del sulfat de coure pentahidratat (calcantita). Amb LIBS es va confirmar que l'únic metall present és el coure. La crosta verda al voltant dels forats no s'ha analitzat.https://infominer.minercat.com/wp-content/uploads/2018/08/corrosio-coure.jpgcorrosio coureFigura 1. Corrosió d'una canalització pluvial de coure. El tub s'ha perforat i al voltant de cada forat hi ha una aurèola verda prima i una crosta blau clara més gruixuda. L'aigua de la pluja ha lixiviat una part d'aquesta crosta blava, que era molt més gruixuda quan es va estudiar la seva composició.2018-08-16T21:29:23+00:00monthlyhttps://infominer.minercat.com/2018/07/15/taula-dintercanvi-de-minerals-de-canyelles/https://infominer.minercat.com/wp-content/uploads/2018/07/p6020073.jpgP6020073https://infominer.minercat.com/wp-content/uploads/2018/07/p6020034.jpgP6020034https://infominer.minercat.com/wp-content/uploads/2018/07/p6020016.jpgP6020016https://infominer.minercat.com/wp-content/uploads/2018/07/foto-10-e1531652844244.jpgFoto 10https://infominer.minercat.com/wp-content/uploads/2018/07/foto-1.jpgFoto 1https://infominer.minercat.com/wp-content/uploads/2018/07/p6020002-1.jpgP6020002 (1)https://infominer.minercat.com/wp-content/uploads/2018/07/foto-7.jpgFoto 7https://infominer.minercat.com/wp-content/uploads/2018/07/foto-9.jpgFoto 9https://infominer.minercat.com/wp-content/uploads/2018/07/donbassita.jpgModified by CombineZPDonbassita de Sallent de Gállegohttps://infominer.minercat.com/wp-content/uploads/2018/07/cechita-ulldemolins.jpgCechita UlldemolinsCechita de Ulldemolins2018-07-15T19:13:47+00:00monthlyhttps://infominer.minercat.com/2018/07/07/revetlla-de-sant-joan-al-gmc/https://infominer.minercat.com/wp-content/uploads/2018/07/img_5648.jpgIMG_5648https://infominer.minercat.com/wp-content/uploads/2018/07/img_5653.jpgIMG_5653https://infominer.minercat.com/wp-content/uploads/2018/07/img_5658.jpgIMG_5658https://infominer.minercat.com/wp-content/uploads/2018/07/img_5659.jpgIMG_5659https://infominer.minercat.com/wp-content/uploads/2018/07/img_5611.jpgIMG_5611https://infominer.minercat.com/wp-content/uploads/2018/07/img_5631.jpgIMG_5631https://infominer.minercat.com/wp-content/uploads/2018/07/img_5636.jpgIMG_56362018-07-09T11:00:18+00:00monthlyhttps://infominer.minercat.com/2018/06/28/cronica-dun-comic-sulfuros/https://infominer.minercat.com/wp-content/uploads/2018/06/conill4.jpgConill4Sumari de Mineralogistes de Catalunya on es pot veure un abstract de l’article sobre el jaciment de Conil, escrit per l’Emilio Sastre l’any 1985https://infominer.minercat.com/wp-content/uploads/2018/06/conill3.jpgConill3Coberta del volum 3, número 1, de l’any VII de Mineralogistes de Catalunyahttps://infominer.minercat.com/wp-content/uploads/2018/06/conill2.jpgConill2Cita del número de Mineralogistes de Catalunya al còmichttps://infominer.minercat.com/wp-content/uploads/2018/06/conill1.jpgConill1Coberta del còmic ‘Historia del azufre de Conil’.2018-09-10T05:43:09+00:00monthlyhttps://infominer.minercat.com/2018/06/22/iii-trobada-interpirenaica-de-micromineralogia-i-sistematica-mineral/https://infominer.minercat.com/wp-content/uploads/2018/06/campro141.jpgcampro14https://infominer.minercat.com/wp-content/uploads/2018/06/p5260092.jpgP5260092https://infominer.minercat.com/wp-content/uploads/2018/06/p5260100.jpgP5260100https://infominer.minercat.com/wp-content/uploads/2018/06/t_p5260058_161.jpgOLYMPUS DIGITAL CAMERAOLYMPUS DIGITAL CAMERAhttps://infominer.minercat.com/wp-content/uploads/2018/06/campro13.jpgcampro13https://infominer.minercat.com/wp-content/uploads/2018/06/campro15.jpgcampro15https://infominer.minercat.com/wp-content/uploads/2018/06/campro14.jpgcampro14https://infominer.minercat.com/wp-content/uploads/2018/06/campro12.jpgcampro12https://infominer.minercat.com/wp-content/uploads/2018/06/whatsa14.jpgwhatsa14https://infominer.minercat.com/wp-content/uploads/2018/06/premis10.jpgpremis102018-06-22T14:32:25+00:00monthlyhttps://infominer.minercat.com/2018/06/10/un-rift-valley-en-miniatura-a-la-segarra-la-fossa-de-ferran-pujalt/https://infominer.minercat.com/wp-content/uploads/2018/06/imgp3743-imgp37461.jpgIMGP3743 - IMGP3746https://infominer.minercat.com/wp-content/uploads/2018/06/imgp3743-imgp3746.jpgIMGP3743 - IMGP3746https://infominer.minercat.com/wp-content/uploads/2018/06/issacparada5-e1528477543105.pngIssacParada5Fig. 8.
