چکیده

توده گرانیتوئیدی ممزار در استان کرمان قرار دارد و از نظر ساختاری در بخش جنوب­شرقی کمان ماگمایی ارومیه­دختر رخنمون یافته است. بر­اساس بررسی­های سنگ­نگاری، این توده از چهار واحد­سنگی دیوریت، تونالیت، گرانودیوریت و مونزوگرانیت تشکیل شده است. این سنگ­ها بیشتر از کانی­های پلاژیوکلاز (آندزین)، فلدسپار قلیایی (ارتوکلاز)، کوارتز، آمفیبول (مگنزیوهورنبلند)، بیوتیت و کلینوپیروکسن تشکیل شده­اند. بررسی­ شیمی دو کانی پلاژیوکلاز و آمفیبول نشان می­دهد که ترکیب پلاژیوکلاز با An 33-47 از نوع آندزین و آمفیبول از نوع مگنزیوهورنبلند (کلسیمی) است که با ماهیت I بودن ماگما همخوانی دارد. بیوتیت­ها نیز دارای نسبت Fe/(Fe+Mg)>0.33 بوده و از منیزیم غنی هستند.  بر اساس نمودار TiO2 نسبت بهAl2O3،  ترکیب آمفیبول­ها نمایانگر دخالت ماگمای گوشته­ای و ترکیبات پوسته­ای در تشکیل آن­هاست. به کار گیری دما- فشارسنج­های مختلف چون مقدار آلومینیوم در هورنبلند و زوج کانی پلاژیوکلاز- هورنبلند نشانگر میانگین فشار حدود 14/1 کیلوبار و دمای 660 تا 730 درجه سانتی­گراد برای توده نفوذی است. شیمی کانی­های بیوتیت و آمفیبول بیانگر آن است که این توده گرانیتوئیدی آهکی قلیایی بوده و در در عمق کمتر از 8 کیلومتری سطح زمین تشکیل شده است.

چکیده [English]

The Mamzar granitoid pluton is located in the Kerman Province and structurally in southeast of Urumieh-Dokhtar magmatic zone. Based on petrographic studies, the granitoid consist of four rock type of diorite, tonalite, granodiorite and monzogranite. They are mainly composed of plagioclase (andesine), alkali-feldspar (orthoclase), quartz, amphibole (magnesiohornblende), biotite and clinopyroxene. Mineral chemistry of plagioclase indicate that their composition are andesine with An33-47 and the amphibole (calcic) have magnesiohornblende compositions that is feature of I-type granite. The biotites with Fe/ (Fe+Mg)>0.33 are magnesio-biotites. Based on TiO2 versus Al2O3 diagram, composition of amphiboles indicate crust and mantle mixing in the formation of the Mamzar granitoid magma. Application of different barometers and thermometers such as Al-in-hornblende, plagioclase-amphibole pair exhibit an average pressure of 1.14 kbar and temperatures of 660-730 °C for the intrusion. The mineral chemistry of the biotites and amphiboles indicate that this granitoid pluton is calc-alkaline and formed at the depth of less than 8 km.
