Chemical Changes in Retrograde Mylonites as a Function of Metamorphic Grade and Deformation Behavior of the Major Rock-Forming Minerals

流体在形变的大陆地壳深处的行为是当前的兴趣。这项研究将检查北卡罗莱纳和弗吉尼亚蓝岭省的逆行绿片岩到低角闪石品位的糜棱岩，那里的初步数据表明变质品位和大块岩石化学变化之间存在反比关系。这项工作涉及矿物组合、氧同位素和矿物化学的表征。研究结果将对理解大陆地壳深处热液流体的行为具有重要意义。

9316954 O'Hara The behavior of fluids at depth in deforming continental crust is of current interest. This study will examine retrograde greenschist to lower amphibolite grade mylonites in the Blue Ridge province of North Carolina and Virginia where preliminary data suggest an inverse relationship between metamorphic grade and bulk- rock chemical change. The work involve characterization of mineral assemblages, oxygen isotopes and mineral chemistries. Results will have important implications for understanding the behavior of hydrothermal fluids at depth in the continental crust.
