The Kiruna mining district, Sweden, known for the type locality of Kiruna-type iron oxide–apatite (IOA) deposits, also hosts several Cu-mineralized deposits including oxide–copper–gold (IOCG), exhalative stratiform Cu-(Fe-Zn), and structurally controlled to stratabound Cu ± Au. However relationship between IOA Cu-systems has not been contextualized within regional tectonic evolution. A broader ...
کانسار مسگرماب در50 کیلومتری شمالشرق شهرستان قائن، در قالب برگه زمین شناسی 1:100.000 آبیز و زون شرقایران واقع شده است. سنگهای آتشفشانیکانسار مسگرماب به سن پالئوسن بالایی- ائوسن، شامل تناوبی ازگدازهها (آندزیت، تراکیآندریت، آندزیت-بازالت و بازالت) و موادآذرآواری (انواع توف وآگلومرا) هستند. این سنگها، بر اساس دادههای ژئوشیمیایی عناصر اصلی وکمیاب، شباهت زیادی بهگدازههای کالکآلکال...
Carbonate-hosted Mn deposits are widespread in North Africa with most of the ores being hosted by Mesozoic dolomitic formations Moroccan Atlasic system. The Bou Arfa Mn(-Fe) deposit described herein is located eastern High Atlas, close to Front, and has accounted for production ~2 Mt ore grading from 33 82% Mn. mineralization occurs within Sinemurian flat-lying dolostones as stratabound karst-f...
In 1975, Social Security beneficiaries were given the option of having their monthly benefit payments sent directly to their banks through an electronic funds transfer system. Since then, beneficiaries have been enrolling in this program in rapidly increasing numbers. At the end of 1976, fewer than 5 million beneficiaries--14 percent of the total--were enrolled in the program. By the end of 198...

The Toodoggone-McConnell Project was inititated in 1996 to map and evaluate a tract of Early Jurassic plutons and surrounding arc volcanic successions of Paleozoic to Jurassic age for base and precious metal mineralization. Bedrock mapping during the first year of the program focussed on a region south of the Finlay River and east of Thutade Lake, documenting local geology near known copper-gol...
We present a study on the Dongguashan quartz diorite stock which is largest Early Cretaceous intrusion associated with skarn-porphyry polymetallic ore deposit in Tongling Ore Cluster, Middle-Lower Yangtze Metallogenic Belt East China. The show massive texture without obvious foliation, and intrusive contact was locally observed inside of stock. anisotropy magnetic susceptibility (AMS) results t...
