We thank the staff of State Key Laboratory of Geological Processes and Mineral Resources, China University of Geosciences, Wuhan and Wuhan Sample Solution Analytical Technology Co for helping with bulk-rock major elementand trace element analyses, zircon U-Pb age and Hf determinations, and whole-...
Chemical zoning within mineral grains can be leveraged to determine the maximum length of time the grains could have remained at magmatic temperatures without being compositionally homogenized by element diffusion16. This study constrains the highest temperature portion of the Mg-suite cooling path by ...
g The cross-sectional TEM image of a sample of C8-BTBT + PS wires (top panel) and the EDX analysis of sulfur element (bottom panel). The interface between the C8-BTBT and PS layers is indicated with blue arrows. h X-ray diffraction spectra taken from patterned C8-BTBT + PS...
indicating that the measured concentrations are well explained by the source contribution estimates. Theχ2value is the weighted sum of squares of the differences between the measured and calculated element concentrations. Ideally, there should be no difference, resulting inχ2of 0. A largeχ2(>4.0...
There are 38 isotopes of zinc, ranging in atomic weights from Zn-54 to Zn-83.Just four of these are stable, and those four, plus one naturally radioactive isotope (Zn-70) that has a very long half-life (5×10+14years), make up the element’s existence onEarth. Their proportional ...
