Ubungakanani bomhlaba obusasazwayo bubumba ukuhanjiswa kwamanzi, ukuxinana, kunye nolwakhiwo lwemingxuma. Amagophe okugcinwa kwamanzi ayatshintsha njengoko iinxalenye zesanti, i-silt, kunye nodongwe zahlukile; umhlaba onesihlabathi ukhupha amanzi ngokukhawuleza, unika ukufuma okuncinci, ngelixa umhlaba wodongwe ugcina amanzi kodwa uthintela ukungena komoya. Umhlaba omdaka unika ukufumaneka kwamanzi okulinganayo, uxhasa ukukhula kweengcambu kunye nokufunxwa kwezondlo. Ukungafani kwe-granulometric kuchaphazela amandla okutshintshiselana kwe-cation kunye ne-micro-porosity, kulawula ukuhamba kwezondlo. Kwezolimo, ubungakanani beencam zomhlaba buchaphazela ngokuthe ngqo ukuchuma kwaye buchaphazela amaqhinga okulungisa. Iindidi zobungakanani beencam zimisela ukulula kokwakhiwa, zichaphazela amandla okuthwala kunye nokufunxwa kwamanzi.

Ukubaluleka kweRubidium Element kuMhlaba
Uxinaniso lweRubidium lubonisa ukuvela komhlaba kunye nokwakheka kweeminerali. Njengophawu lokulandelela, irubidium ihambelana nefeldspar kunye ne-mica, ezininzi kumatye e-siliceous. Ukusasazwa kwayo kubonisa ukuba izinto ezizalayo zinamandla; umhlaba we-siliceous uhlala ubonisa amanqanaba aphezulu e-rubidium, nto leyo enceda ukwahluka kokwakheka. Ubukho beRubidium buxhasa izifundo zemvelaphi kunye nokulandelela okusingqongileyo kuhlalutyo lomhlaba. Ukuhlelwa kokwakheka komhlaba ngokobukhulu beesuntswana, kudityaniswe nemephu yerubidium, kuphucula ukuchongwa kwezinto ezizalayo zomhlaba kwaye kwazisa uhlalutyo lokwakheka kwezinto ezisisiseko kusetyenziswa izixhobo ze-XRF.
I-Rubidium njengoMboniso woBukhulu beeNgcawu zoMhlaba
I-Rubidium idla ngokugxininisa kwi-feldspar kunye neeminerali ze-mica, ezilawula izinto ezizalayo ze-siliceous. Umhlaba we-siliceous ubonisa uxinano lwe-rubidium luqala kwi-20 ukuya kwi-150 mg/kg, kunye nokuguquguquka okukhulu kwendawo okunxulunyaniswa nobunzulu bemozulu kunye neeprofayili zezimbiwa. Kumhlaba we-limestone, amanqanaba e-rubidium awadluli kwi-50 mg/kg, ebonisa ubukho obuncinci beeminerali ze-felsic kunye nemvelaphi ye-geochemical ehambelanayo. Utshintsho kwi-rubidium luhambelana ngokucacileyo nomgangatho wotshintsho lwezimbiwa kunye nezinto ezizalayo zomhlaba, ezixhasa ukusetyenziswa kwayo njengophawu oluqinileyo lombhalo.
Indlela Amanqanaba eRubidium Aqikelela Ngayo I-Granulometry Yomhlaba
Uxinaniso lweRubidium luhambelana ngokuthe ngqo namaqhezu obungakanani beesuntswana kumhlaba wesilika. Amaqhezu amancinci afana nodongwe kunye nesilika agcina irubidium ephezulu ngenxa yendawo yomphezulu weeminerali kunye nomxholo we-mica, kunye namaqhezu odongwe adla ngokudlula i-100 mg/kg kumhlaba wesilika. Amaqhezu entlabathi eqinileyo abonisa irubidium ephantsi, ngakumbi kumhlaba ovela kwilitye lekalika. Ukulinganiswa kwe-XRF, kuqinisekiswe yiILonnmeter I-EDXRF, kuvumela ukulinganiswa okukhawulezileyo kuyo yonke i-spectrum yobukhulu bengqolowa, okwenza kube lula ukuhlelwa kobume bomhlaba kunye nokumaphu ngokusebenzisa imisebenzi ye-geostatistical eqinileyo. Uhlalutyo olubanzi lwedatha luqinisa ixabiso le-rubidium kwiimodeli eziqikelelayo zokusasazwa kobungakanani bezinto zomhlaba kwizifundo zezolimo nezendalo.
Ukujongana nobukhulu beenxalenye zomhlaba kunye nezinto eziphilayo eziguquguqukayo
Ubungakanani bamasuntswana kunye notshintsho lomxholo wendalo kunempembelelo encinci ekulinganisweni kwe-XRF rubidium. Izifundo zakutshanje zibonisa ukuba ukungalingani komlinganiselo akunamsebenzi kwimihlaba enobukhulu beenkozo phakathi kwe-20 µm kunye ne-2 mm kunye nomxholo wendalo ongaphantsi kwe-12%. Ukulinganisa ngokuchasene nomhlaba osetyenzisiweyo kuphucula ngakumbi ukuchaneka, kuxhasa ukuhlelwa kwezinto zomhlaba ezithembekileyo kunye novavanyo lokuthungwa.
