Summary
This study quantifies trace element partitioning between minerals like hibonite, melilite, and spinel and silicate melts. These findings are crucial for understanding the early solar system, including chondrites and Calcium-Aluminum-Rich Inclusions (CAI).
Area of Science:
- Cosmochemistry
- Geochemistry
- Planetary Science
Background:
- Chondrites and Calcium-Aluminum-Rich Inclusions (CAI) are fundamental to understanding solar system formation.
- Mineral/melt partitioning data is essential for modeling early planetary processes.
Purpose of the Study:
- To experimentally determine mineral/melt partition coefficients for numerous trace elements.
- To provide new data relevant to the evolution of chondrites and CAI.
Main Methods:
- High-temperature experiments (1350-1550°C) simulating early solar system conditions.
- Analysis of experimental run products using electron microprobe (EMPA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS).
Main Results:
- Experimentally determined partition coefficients for 38 trace elements between hibonite, melilite, spinel, and silicate melts.
- Comprehensive dataset covering a wide range of lithophile and siderophile elements.
Conclusions:
- The generated data offers critical insights into trace element behavior during the formation of early solar system materials.
- This research aids in refining models of chondrite and CAI formation and evolution.

The distribution law or Nernst's distribution law is the law that governs the distribution of a solute between two immiscible solvents. This law, also known as the partition law, states that if a solute is added to the mixture of two immiscible solvents at a constant temperature, the solute is distributed between the two solvents in such a way that the ratio of solute concentrations in the solvents remains constant at equilibrium.

02:37Experimental Determination of Chemical Formula
47.1K
The elemental makeup of a compound defines its chemical identity, and chemical formulas are the most concise way of representing this elemental makeup. When a compound’s formula is unknown, measuring the mass of its constituent elements is often the first step in determining the formula experimentally.

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...

02:39Phase Transitions: Melting and Freezing
15.2K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...
