Аксинитовые соросиликатные силикаты. . Отличное видео
Zamkatimu:
Axinite ndi dzina lodziwika bwino la mitundu inayi ya mchere.
Gulani miyala yamtengo wapatali yachilengedwe m'sitolo yathu ya miyala yamtengo wapatali
mwala wa axinite
Kuchokera ku gulu la silicates, gulu laling'ono la sorosilicates. Onsewa ndi triclinic borosilicates ndi chilinganizo: Ca2(Fe, Mg, Mn) Al2[BO3OH, Si4O12].
Adapezedwa kumapeto kwa zaka za zana la XNUMX ndi a Jean-Godefroy Schreiber. Ku Oisan, katswiri wa zachilengedwe uyu alinso ndi ngongole chifukwa chopeza Stilbit ndi Anatas. Kufotokozera koyamba kukukhudza mchere wa Rome de Lisle. Anatchedwa René-Just Hayuy.
Mawuwa amachokera ku Greek axinè = nkhwangwa. Chifukwa cha mawonekedwe a kristalo. Dzina la mwala limagwirizanitsidwa ndi malo a makhiristo. Zimatengera mawonekedwe ofanana ndi nkhwangwa kumbali ya X. René-Just Haüy.
Mapangidwe a miyala ali ndi [Si4O12]8- ndi BO3 mphete. mphete zimaŵetedwa kufanana wina ndi mzake. Ndipo pafupifupi kufanana ndi (010) ndege. Chitsulo mu octahedral udindo amalumikiza magulu kumeneko. Komanso aluminium mu mgwirizano wa tetrahedral ndi octahedral. Ndipo kudzera mu calcium, yomwe ili pakatikati pa polyhedron yosakhazikika yokhala ndi oxygenates 10.
Chemistry ya miyala yamtengo wapatali ya axinite
Mfundo yofunika kwambiri mu chemistry ya silicate iyi ndi kukhalapo kwa boron wambiri. Kuchuluka kwa calcium kumakhalabe kosasintha. Komabe, chitsulo, monga manganese, chimatha kusintha mosiyanasiyana. Zowoneka bwino za mwala zimagwirizana kwambiri ndi zomwe zili muzinthu zitatuzi.
Mafomu {110}, {-110}, {1-11} apangidwa. Nkhope nthawi zambiri zimakhala ndi nthiti pang'ono. Ndipo amapanga ngodya zakuthwa, zomwe zimapatsa mcherewo mawonekedwe akuthwa.
Mineral metamorphic kukhudzana ndi metasomatism. Amapezeka m'madipoziti a miyala yamchere. Komanso m'miyala yosinthika yosinthika yomwe imakhudzidwa ndi metamorphism ndikuyambitsa boron.
Mu crystalline schists metamorphosed ndi granite.
Titha kuzipeza ndi ma silicates ena olemera a calcium komanso boron. Monga tourmalines, datolite, calcium amphibole, actinolite, zosite, calcite, komanso quartz.
Gulu la miyala ya axinite
- ferroaxinite, Ca2Fe2 + Al2BOSi4O15(OH) wolemera muchitsulo, komanso carnation, bulauni, maula buluu, ngale imvi.
- Magnesioaxinite, Ca2MgAl2BOSi4O15(OH), wolemera mu magnesium, komanso buluu wopepuka mpaka wofiirira, wofiirira mpaka pinki.
- manganaxinite, Ca2Mn2 + Al2BOSi4O15 (OH) wolemera mu manganese, komanso uchi wachikasu, clove bulauni, bulauni mpaka buluu.
- tinzenite, (CaFe2 + Mn2 +) 3Al2BOSi4O15 (OH) chitsulo, komanso manganese wapakatikati, wachikasu, wofiirira wachikasu wobiriwira.
