چکیده

در این پژوهش، رخداد کانی سپیولیت برای نخستین بار از سنگ­های فرامافیک توالی افیولیتی شمال نائین گزارش می­شود. سپیولیت کانی رسی آبدار با ساختار الیافی است که به­واسطه ویژگی­های منحصر به فرد خود در صنایع مختلف کاربرد دارد. تشکیل سپیولیت، پیامد واکنش­های متعددی است که در سنگ­های فرامافیک توالی افیولیتی شمال نائین رخ داده است. این فرایند طی سه مرحله اصلی انجام شده است. ابتدا سیالات گرمابی با تاثیر بر سنگ­های فرامافیک، آنها را به سرپانتینیت تبدیل کرده­اند. هجوم سیالات دارای CO2-H2O در امتداد سطوح ضعف سرپانتینیت­های برشی و خرد شده، باعث انحلال سرپانتینیت و کربناته شدن آن شده­اند. طی کربناته شدن سرپانتینیت­ها، واکنش بین سنگ­های فرابازی با محلول­های گرمابی سبب تشکیل محلولی غنی از Mg  و/یا  Si در دمای پائین شده و سرانجام، کانی سپیولیت در نتیجه فعالیت سیالات گرمابی غنی از CO2،H2O و SiO2 شکل گرفته است.

چکیده [English]

This is the first report on sepiolite occurrences from ultramafics of Nain ophiolitic sequence. Sepiolite is a hydrous clay mineral with fibrous structure that is very important for industrial applications due to properties. Formation of sepiolite is related to several reactions in ultramafics of Nain ophiolite. This process is carried out in three main stages. At first, the hydrothermal fluids have been affected on ultramafic rocks so they altered to serpentinite. The influx of CO2-H2O bearing fluids along shear zones in serpentinized and brecciated ultrabasics caused dissolution and carbonatization of serpentinites. During the carbonation of serpentinite, reaction between ultrabasics with hydrothermal fluids have led to formation of Mg and/or SiO2 bearing solutions at low temperatures, and finally, sepiolite resulted from interaction of  CO2, H2O rich hydrothermal fluids.
