Kungani iCave of the Crystals noma iGiant Crystal Cave ivaliwe emphakathini?
Context:I-Cave of the Crystals noma i-Giant Crystal Cave (Spanish) ngumhume oxhumene neMayini yaseNaica ekujuleni kwamamitha angama-300 (980 ft), eNaica, Chihuahua, eMexico. Kuthatha isimo segumbi ngaphakathi kwedwala le-limestone lomnikazi wemayini, futhi licishe libe ngamamitha ayi-109 (358 ft) ubude nomthamo wamamitha ayi-cubic ayi-5,000 kuya ku-6,000 (180,000 kuya ku-210,000 cu ft).  Leli kamelo liqukethe amakristalu amakhulu e-selenite (i-gypsum, i-CaSO4 · 2 H2O), amanye amakristalu emvelo amakhulu kunawo wonke ake atholakala. Okukhulu kunakho konke kungamamitha angu-11,40 (37,4 ft), nomthamo ongamamitha ayi-cubic angu-5 (180 cu ft), nobunzima obulinganiselwa kumathani ayi-12. Lapho lingenawo amanzi, umhume ushisa kakhulu, izinga lokushisa lomoya lifinyelela ku-58 ° C (136 ° F) kanye nomswakama wamaphesenti angu-90 kuya kwangu-99. Lokhu kungaqhathaniswa namarekhodi okushisa eSigodini Sokufa, kodwa kunomoya omanzi kakhulu. Ngenxa yalezi zizathu, lo mgodi awukacwaningwa. Ngaphandle kokuvikelwa okufanele, abantu bangabekezelela ukuchayeka cishe imizuzu eyishumi ngesikhathi.  Umhume watholakala ngo-April 2000 ngabazalwane uJuan noPedro Sánchez ngesikhathi bebhora emayini. Ngo-October 2015, lo mgodi wawusubuye wagcwala futhi umhume waphinde wagcwala amanzi anothe ngamaminerali adingekayo ukuze amakristalu akhule.  Iqembu lososayensi beProjekthi yaseNaica belilokhu lizihlola lezi zimfudu.
Izimo emhumeni azizinhle, ukushisa okukhulu nomswakama, amakristalu abukhali agobhozayo ayingozi kubantu.
