<p>در چهار کیلومتری جنوب شرقی لاهیجان تشکیلات دولومیتی و آهک، همخوان با سازندهای سلطانیه و پالئوزونیک، در اثر نفوذ و تزریق توده گرانیتی به مرمر دانه درشت گرانوبلاستی تبدیل ...</p>
<p>Do lomites and limestones o f simmilar age as Soltanieh and<br>
paleozoic forma tio ns have been tr ansformed to coa rse grained<br>
granoblas tic marbles due to in tru sion of granitic masses, located 4 km<br>
southeast of Lahijan, Iran, and barite mine ralization have also occurred.<br>
Ore mine ra ls are mos tly co ncentr a ted along th e rracture zones in<br>
do lo mites and mining activeities in the past was foc used on these<br>
fractures and breccia zones. Studies of polished sections under the ore<br>
microscope have shown that the major o re mine rals occurring in veins<br>
contain magne tit e, pyr ite,pyrot ite chalcopyrite, hematite, goetite, and<br>
C'I ~ M g- Fc s ili ca t e~ such as phlogo pite, talk, act inolite, thremolite,<br>
diopsidc and chlorite. Magnetite is the major iron mine ral in skarn. This<br>
mineral and pyro tit c are considered to be primary and the remaining<br>
minerals are considered as second ary. Barite veins with eas t~wes t trends<br>
formed by hydrothe rmal activi ties are o bserved in dolomiti and schists<br>
ri ght next to the intru sio ns, a round villages such as Di zin and<br>
Sarches hmeh. Conside ring the min eralogy, texture and stru cture or<br>
these ve in s, it is probab le that they a re crys tallized in fractures at<br>
temperatures below 500</p>
