I-Jade: I-Intersection of Geology and Culture

I-Jade iyigugu eliyigugu eliye laziswa izinkulungwane zeminyaka ngamasiko emhlabeni jikelele. Kusukela ebukhosini basendulo baseShayina kuya empucukweni yamaMaya eMesoamerica, i-jade ibe nokubaluleka okukhethekile emikhubeni yamasiko nengokomoya yemiphakathi eminingi. Kodwa ngale kokubaluleka kwayo ngokomlando nangokwesiko, i-jade nayo iyisihloko esithakazelisa izazi zokwakheka komhlaba okufanele zifundwe. Kulokhu okuthunyelwe, sizohlola ukuhlangana kokwakheka komhlaba namasiko njengoba kuhlobene naleli tshe eliyingqayizivele nelibalulekile.

I-Jade yigama elisetshenziselwa ukuchaza izinhlobo ezimbili zamaminerali: i-nephrite ne-jadeite. I-Nephrite iwuhlobo lwe-amphibole mineral, kuyilapho i-jadeite iyiminerali ye-pyroxene. Womabili amaminerali aqinile ngendlela emangalisayo futhi ahlala isikhathi eside, okwenza afanelekele ukusetshenziswa kumathuluzi, izikhali, nezinto zokuhlobisa. I-Nephrite ngokuvamile iluhlaza okotshani or umbala omhlophe, kuyilapho i-jadeite ingahluka ukusuka komhlophe kuye koluhlaza, kanye neminye imibala enjengobomvana, onsomi, nobomvu.

Ngokwe-geologically, i-jade yakheka emadwaleni e-metamorphic, okungamatshe ashintshwe ukushisa, ukucindezela, kanye nezinqubo zamakhemikhali. Lawa matshe angatholakala ezindaweni eziningana emhlabeni jikelele, kuhlanganise eSiberia, eCanada, eNew Zealand naseMyanmar. Nokho, i-jade eyigugu futhi efunwa kakhulu ivela esifundazweni saseKachin eMyanmar, lapho kutholakala khona i-jadeite yezinga eliphezulu.

Njengoba sibona, i-geology idlala indima ebaluleke kakhulu ukuqeqeshwa kanye nokusatshalaliswa kwe-jade. Kodwa-ke, kubalulekile futhi ukucabangela ukubaluleka kwamasiko kwaleli tshe eliyigugu. Ngokwesibonelo, eChina, i-jade iye yaziswa izinkulungwane zeminyaka futhi ibhekwa njengophawu lwengcebo nesimo. AmaShayina asendulo ayekholelwa ukuthi i-jade inamandla okwelapha futhi ingakhuthaza inhlanhla nokuphila isikhathi eside. E-Mesoamerica, impucuko yamaMaya nayo yazisa i-jade futhi yayifaka ezintweni zabo eziningi zemikhosi nezinto zobuciko.

Ngakho-ke, singabona ukuthi indaba ye-jade iwukuxhumana okuthakazelisayo phakathi kwe-geology namasiko. I-Geology ihlinzeka ngesisekelo esibonakalayo sokwakheka nokusabalalisa itshe eliyigugu, kuyilapho isiko siligxilisa ngokubaluleka okungokomoya nomlando. Ngezindlela eziningi, i-jade isebenza njengesikhumbuzo sokuhlangana kwesayensi nolwazi lomuntu.

I-Jade isalokhu iyitshe eliyigugu kumasiko amaningi, lokhu kubonisa ukuthi i-geology ayibalulekile kanjani nje ukwazi ukwakheka kwezinto kodwa futhi nokuqonda ukuthi isetshenziswe kanjani ngokuhamba kwesikhathi. Ukuqonda ukuphambana kwe-geology namasiko maqondana ne-jade kungajulisa ukwazisa kwethu kokubili itshe eliyigugu ngokwalo kanye nemiphakathi eliye yalazisa iminyaka eminingi kangaka.
