چکیده مقاله :
کانسار باریت حور، واقع در واحدهای رسوبی ماسه‌سنگی و شیلی، به عنوان یک کانسار هیدروترمال رگه‌ای در محیط قاره‌ای شکل گرفته است. این پژوهش با هدف بررسی زمین‌شیمی و کانی‌شناسی این کانسار و تعیین منشأ و شرایط تشکیل آن انجام شد. توزیع عناصر نادر خاکی (REEs) در نمونه‌های باریت نشان‌دهنده غنی‌شدگی از عناصر نادر خاکی سبک (LREE) نسبت به عناصر نادر خاکی سنگین (HREE) و وجود آنومالی‌های مثبت Ce و منفی Eu است که به شرایط اکسایش-کاهش خاصی در محیط تشکیل اشاره دارد. مقادیر پایین ΣREEs و نسبت‌های LREE/HREE در باریت‌های کانسار حور نیز دلالت بر منشأ هیدروترمالی این کانسار دارند. علاوه بر این، شواهد ساختاری و بافتی، از جمله حضور رگه‌های چند مرحله‌ای و خردشدگی بلورها، تأیید می‌کنند که کانی‌سازی باریت در این منطقه تحت تأثیر فرآیندهای تکتونیکی و سیالات هیدروترمالی صورت گرفته است. نتایج این پژوهش نشان می‌دهد که کانسار باریت حور مشابه با ذخایر گرمابی در محیط‌های قاره‌ای بوده و منشأ آن از سیالات هیدروترمالی است که در شرایط تکتونیکی فعال به رگه‌ها و رگچه‌های باریت منجر شده است.
The Hour Barite deposit, located within sedimentary units of sandstone and shale, has formed as a hydrothermal vein-type deposit in a continental environment. This study aims to investigate the geochemistry and mineralogy of this deposit, as well as to determine its origin and formation conditions. The distribution of rare earth elements (REEs) in the barite samples indicates enrichment of light rare earth elements (LREEs) relative to heavy rare earth elements (HREEs), along with the presence of positive Ce and negative Eu anomalies, which suggest specific oxidation-reduction conditions in the formation environment. The low ΣREEs values and LREE/HREE ratios in the Hour deposit's barites further indicate a hydrothermal origin for this deposit. Additionally, structural and textural evidence, including the presence of multi-phase veins and crystal fragmentation, confirm that barite mineralization in this area was influenced by tectonic processes and hydrothermal fluids. The results of this study suggest that the Hour Barite deposit is similar to other hydrothermal deposits in continental environments, with its origin attributed to hydrothermal fluids that, under active tectonic conditions, led to the formation of barite veins and vein
