آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

Anomalously silver-rich vein-hosted mineralisation in disseminated-style gold deposits, Jiaodong gold district, China

IOCG Deposits: A Cordilleran Perspective

During the latter part of the Phanerozoic, numerous iron oxide(-Cu-Au) (IOCG) systems formed in parts of the Cordillera of North and South America. They occur in diverse tectonic and magmatic settings with considerable variety in deposit associations and characteristics. Although there are general patterns, there is no simple, all-encompassing descriptive model; a comparison with the diversity ...

Mineralogical and chemical characteristics of five nontronites and Fe-rich smectites

Nontronites are the ferric members of dioctahedral smectites, most of which are structural counterparts of beidellite (Brindley, 1980). The existence of a cont inuous b e i d e l l i t e n o n t r o n i t e series was suggested on the basis of chemical analyses by Ross & Hendricks (1945). However, a nontronite with montmorillonitic structure has been described by KSster (1982). Minor amounts of...
