Experimental Divalent Element Partitioning between Anorthite and Cai Melt
Introduction: A quantitative description of crystal-liquid trace element partitioning is critical to understanding the igneous differentiation history of the terrestrial planets. Anorthitic plagioclase is the type mineral of terrestrial planet crusts, and for the Moon, specifically, quantitative understanding of trace element partitioning in anorthite is key to testing models of the lunar magma...
متن کاملApatite-Melt Volatile Partitioning Under Lunar Conditions
Introduction: The volatile component of apatite [Ca5(PO4)3(F,Cl,OH)] makes it a popular choice for studying the abundance and distribution of indigenous lunar volatiles [e.g. 1-5]. The thermodynamic behavior of volatile partitioning into apatite is, however, poorly constrained. Limited experimental studies of apatite/melt partitioning have focused on terrestrial systems [6], chlorine-brine syst...
متن کاملTheTemperature and Pressure Dependence of Nickel Partitioning between Olivine and Silicate Melt
We measured Ni partitioning between olivine and melt, D Ni , in experiments on mid-ocean ridge basalt (MORB) encapsulated in olivine at pressures from 1atm to 3·0 GPa and temperatures from 1400 to 15508C.We present a series of experiments where the temperature (T) at each pressure (P) was selected so that the liquid composition remained approximately constant over the entire P^T range.This appr...
متن کاملExperimental study of trace element partitioning between lunar orthopyroxene and anhydrous silicate melt: effects of lithium and iron
Orthopyroxene (Opx) was present during a significant portion of crystallisation of the lunar magma ocean, but its influence on co-existing melt trace element contents is not well quantified. We performed high-pressure (P, 1.1 to 3.2 GPa), high-temperature (T, 1400 to 1600 °C) experiments on synthetic Fe-rich compositions at reducing conditions relevant to the lunar mantle to constrain trace ele...
متن کاملa comparative study of the relationship between self-, peer-, and teacher-assessments in productive skills
تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...
