I-Jasper iwuhlobo lwetshe eliyigugu elakhiwe nge-microcrystalline asebenza ngebhethri futhi yaziwa ngamaphethini ayo amahle futhi ahlukahlukene. Lawa maphethini akhiwa njengoba kwakhiwa ijaspi, enamaminerali ahlukahlukene nokungcola okuthonya umbala nomklamo womkhiqizo wokugcina.
Ngokombono we-geology, i-jasper ihlukaniswa njengetshe le-sedimentary, okusho ukuthi yakha kusuka ku-sediment efakwe futhi yahlanganiswa ngokuhamba kwesikhathi. Ivame ukutholakala ezitsheni ze-sedimentary futhi idalwe ngenqubo yokwenza i-silica, lapho uketshezi olucebile nge-silica lugeleza phakathi kwenhlabathi bese lubuyisela izinto zangempela nge-quartz.
Esinye sezici ezithakazelisa kakhulu zejaspi ububanzi bemibala namaphethini engabonisa. Amanye amatshe ejaspi aqinile ngombala, kanti amanye anebhande eliyinkimbinkimbi or amaphethini ajikelezayo. Imibala ehlukahlukene yejaspi ingenxa yokuba khona kwamaminerali ahlukahlukene nokungcola, okufana ne-iron oxide noma ubumba.
Ngokuya nge-mineralogy, i-jasper ibhekwa njengenhlobonhlobo ye-quartz futhi yenziwe ngamakristalu e-quartz amancane, ahlanganiswe eduze. Lawa makristalu anikeza ijaspi ubulukhuni nokuqina kwayo, okwenza kube ukukhetha okudumile ukusetshenziswa ebucwebeni nasezintweni zokuhlobisa.
I-Jasper ibilokhu yaziswa abantu izinkulungwane zeminyaka, nobufakazi bokusetshenziswa kwayo kusukela empucukweni yasendulo. Isetshenziswe ngezindlela ezihlukahlukene, kuhlanganise njengetshe eliyigugu, impahla yokuhlobisa, ngisho nanjengethuluzi. Namuhla, i-jasper isaqhubeka iyisinqumo esithandwayo sokusetshenziselwa ubucwebe nezinto zokuhlobisa, futhi ifunwa kakhulu ngabaqoqi nabashisekayo.
Sengiphetha, i-jasper iyitshe eliyigugu elithakazelisayo elakhiwa ngenqubo ye-silicification futhi libonakala ngamaphethini alo amahle futhi ahlukahlukene. Ngokombono we-geology, iyidwala le-sedimentary elakhiwe i-microcrystalline quartz futhi laziwa ngokuqina nokuguquguquka. Kungakhathaliseki ukuthi uchwepheshe we-mineralogist noma ungumuntu nje owazisa ubuhle bezinto zemvelo, i-jasper iyitshe eliyigugu okufanele lihlolwe.
