Ohaksang

Ohaksang, jinsi kuhin tahshinist, ki asosan az kalsit SaSOz va bazan az aragonit iborat ast. Tarkibash aksariat omekhtahoi dolomit, kvars, mineralhoi gildor, oksidho, gidrooksidhoi ohan, mangan, inchunin markazit, fosfatho, gaj, moddahoi organiki va gayra dorad. Tarkibi khimiyavii Ohaksangi toza ba tarkibi kalsit (56% SaO va 44% SOg) nazdik ast. Agar Ohaksang 4—17%’ MgO doshta boshad, onro Ohaksangi dolomitgashta, 25— 50% zarrahoi gili doshta boshad, mergel menomand.

Buri tabiii 96— 99%* SaSOz doshta niz Ohangsang ast. Dar prosessi metamorfizm Ohaksang ba marmar tabdil meyobad. Ohaksangho vobasta ba andozai donahoi tarkibashon gunogun va az rui sokht kristalli, organogeni, shikastapora va omekhta mesha­vand. Ohaksangho beshtar qabat-qabat mekhoband. Ohaksangi organogeni az cham shu­da mondani boqimondahoi organiki, Ohaksangi khemogeni bo rohi az mahlulho takshon shudani kalsit va Ohaksangi shi­kastapora dar natichai jam va shakh shuda mondani shikastaporahoi ohaksanghoi qadima ba vujud meoyand. Ohaksang dar shakli qabathoi gafs (az sadho to hazorho m) dar tahnishasthoi tamomi sistemahoi geologi (az tokembriy to antropogen) vomekhurad. Dar Tojikiston Ohaksang beshtar dar qatorkuhhoi Qurama, Zarafshon, Hisor va katorkuhhoi Darvozu Pomir vomekhurad.

Dar khojagii khalq Ohaksang aha­miyati kalon dorad. Az on ohak, se­ment tayyor mekunand. Dar sokhtmoni korkhonahoi sanoati, manzilgoh va rohho hamchun sang, shagal, sanghoi ruykashiyu oroishi ba kor meravad. Ohaksangro dar sanoati khimiya (baroi tay­yor kardani soha, karbidi kalsiy, nurii minerali va gayra), metallurgiya (ba sifati flyus), poligrafiya (ba­roi sokhtani sanghoi litografi), sanoati shisha, khurokvori (baroi sofkorii sharbati lablabui qand) va gayra farovon istifoda mebarand.
