The composition and origin of Earth’s early crust remains hotly debated. Here we use partition coefficients to invert the trace element composition of 4.3-3.3 Gyr Jack Hills zircons to calculate the composition of the melts from which they crystallised. These were conducted using a new aliquot of zircons and ages were obtained using standard SHRIMP methodology, with trace elements determined by standard LA-ICP-MS techniques.
地球早期地壳的组成和起源仍然争论不休。在这里，我们使用分配系数来反演4.3-3.3 Gyr Jack Hills锆石的微量元素组成，以计算它们结晶的熔体的组成。采用新的锆石等分法测定锆石年龄，采用标准SHRIMP法测定锆石年龄，采用标准LA-ICP-MS法测定微量元素。
