Experimental Studies Of Fe-Mg Carbonates And Their Role In Petrogenesis
Experimental Studies Of Fe-Mg Carbonates And Their Role In Petrogenesis
Andrea M. Koziol
The occurrence of carbonate minerals in rocks and sediments is a mark of the interaction of the biosphere, hydrosphere, and atmosphere with the lithosphere. The studies described in this proposal will help geologists understand the conditions of formation of banded iron formations, carbonatites, and magnesite-bearing eclogites, among other parageneses.
The objectives of this study are to determine siderite (FeCO3), magnesite (MgCO3), and CO2 thermodynamic properties and the mixing relations of siderite-magnesite solid solutions. Selected carbonate univariant equilibria, experimentally reversed over a wide range of pressure and temperature, will provide this information. The equilibria siderite + hematite = magnetite + CO2, …

Eastern New England is now recognized to consist of a number of exotic terranes joined to ancestral North America along large faults. However, the timing of the accretion of these terranes is in a state of flux. This project will gather thermometric and barometric data from both sides of these terrane bounding faults and together with existing age determinations will assess the possibility of major Alleghenian motion, not previously recognized. Results have the potential to provide a major re-interpretation of the timing of terrane accretion in New England.

This award will provide half of the funds needed for the acquisition of an electron microprobe. This new electron microscope will primarily serve the needs of the Geology faculty and graduate students in the Department of Geological Sciences at The University of Indiana. The University of Indiana is committed to provide the additional funds to make this acquisition possible. Seven Geology Department faculty and their students have been identified as primary users. Six other faculty expect to be less frequent or occasional users. This large group of faculty and their students pursue research in diverse areas (e.g. thermodynamic links between …
