<p dir="RTL">کانسار اهن جلال آباد زرند یکی از هفت کانسار مهم در ایران مرکزی است که ذخیره 4/200 میلیون تن سنگ آهن با عیر متوسط 2/44% آهن ، 83/0% گوگرد و 7/0 فسفر برآورده شده است. در این کانسار دو نوع توده معدنی قابل تشخیص...</p>
<p>The Jalal Abad iron ore deposit is one of the seven<br>
most important iron ore deposilS in the central Iran. with a<br>
probable are reserve of 200.4 million tons of iron ore in which<br>
the average grades are estimated as 44.28% Fe, 0.83% Sand<br>
0.07%P. In the Jalal Abad deposit two types of orebodies are<br>
identified: the orebodies which are concordant with respect to<br>
the sedimentarY most rocks (Jalal Abad I). and the orebodies<br>
which are discordant with respect to their carbonate host. rocks<br>
(Jalal Abad II). In this deposit the primary ore minerals are<br>
magnetile and hematite. Hematite is also formed from the<br>
oxidation of magnetite. It is proposed that the deposit was<br>
rormed in two stages as describled below.<br>
1) The principal orebodies were 'formed contemporaneous with<br>
the sedimentation. from the exbalites and precipitates associated<br>
with volcanic activity within an intracontinental sources. This<br>
pan of the deposit is named Jalal Abad l.<br>
2) After formation of the Jalal Abad orebodies. due to<br>
emplacement or the igneous rocks within the ore zone, the<br>
meteoric and/or connate water contained in the Jalal Abad J:<br>
then iron was redeposited from the upwelling iron bearing<br>
solution as replace,m ent orebo<1ies within the carbonate rocks. 1n<br>
this manner JalaJ Abad II orebodies were formed.</p>
